Solar Power Innovations Solar Power has been observed as early as the year of 1839 by a French physicist named Alexandre-Edmond Becquerel. He invented the first photovoltaic cell. Since then his studies and works have been perfected on and continue to change the world in which we live for the better. Photovoltaic cells have constantly been evolving ever since. In 1883, Charles Fritts built the first solid state photovoltaic cell using materials such as gold and selenium. With further advances to the system, scientist were able to recreate the cell in a way that could serve as an alternative power source on the satellite named Vanguard that was flown into space in the year of 1958. In the 1970’s there was an oil crisis when Middle Eastern countries proclaimed a trading ban, encouraging oil companies to buy solar firms. Funded research allowed for first, second and third generation cells to be constructed. Currently, the cost of solar energy has exponentially decreased with the falling price of silicon, allowing for many new innovations to take place. Thin solar film is a second generation cell that is being commercially used. The creation of solar thin film allowed us to reduce cost even further as it is printed in rolls which can be incorporated into things like building materials instead of having to have big bulky expensive panels. The film is lightweight, flexible and most importantly, affordable. Over the past few years, the thin solar film has become more efficient

Solar panels utilize photovoltaic power in large quantities, a method that became possible following the discovery of the silicon cell in 1954. A photovoltaic power system was developed for El Paso in 1980. Photovoltaics are
Solar power used to be harnessed only for those with resources, although that changed when Prof. Vivian Alberts created a thin metallic film at the University of Johannesburg. This technology has made solar electricity five times cheaper than the previously used solar cells, making solar power a more
The Sun’s energy out powers all of the energy sources made on Earth. Even though only a fraction of the Sun’s energy makes it to Earth, it is still ten-thousand more times powerful than the energy sources on Earth. However, we are unable to harness such energy because of the many breaches we have to past through to achieve solar energy. As well, solar energy lacks certain aspects causing fossil fuels to be valued more. Although, by creating engineering advancements to improve the efficiency, expenditure, and availability of solar energy, the problem of solar energy usage will be resolved.
In 1954 Bell Laboratories invented the first photovoltaic (or solar) cell, made from the semi-conductor silicon, and other elements. It was the first way to convert sunlight directly into electricity. When the space program was launched in the 60's, it
Solar industry has been paying lots of attention to coating technology in the past 10 years. Solar energy is considered the future of alternative energy sources. It has been recognized as one of the most widely used renewable sources of energy in the few recent years for its non-polluting characteristics which combats the Greenhouse effect on global climate created by the use of fossil fuels, figure 1.6. The generation of solar power is done by converting the solar energy into electricity by using either photo-voltaic (PV) solar cells (direct method) or concentrated solar power (CSP). Photoelectric effect is used by PV cells to convert solar energy into electric energy. With the rapid growth of solar energy harvesting as a clean source of power, the enhancement of solar cell efficiency grabs more attention nowadays.
The greatest energy that can be produced by the sun is electricity. Photovoltaics, or solar cells, capture the sun and convert it into electricity. Solar cells were discovered by the Europeans back in the 1870’s when they used selenium to develop the telegraph. They found that when light hits selenium it would produce and electrical current. Soon enough there were many scientists and engineers working on photovoltaic systems. Silicon and Selenium proved to be the two best elements to conduct electricity when light hits them. Photovoltaic systems (PV cell) work by converting the suns light into electricity. A semi conducting material absorbs the sunlight, that energy knocks electrons loose from their atoms, this allows the electrons to flow through the material to produce electricity. The further development of solar cells can be attributed to the satellite industry. Solar cells were expensive and there was no use for them until satellites came. Because it is impractical to tether satellites it became important to develop solar energy at any cost that would power these satellites. This created a sustainable market for solar power, the first of its kind.
Imagine a world without light, a world filled with so much darkness that it would be nearly impossible to see anything, to use anything or to even function. A world without light would be a world without energy, without being able to use our phones 24/7, a world without all the comforts, mainly a world with hardships and struggles. We live in a world where energy is needed for everything. Nothing really works without electricity. For example, Energy is constantly being used to charge cellular devices, warm food in the microwave or even to charge electrical cars. The world is shifting it went from the extracting of unnatural fossil fuels to the discovery of a more natural way call solar energy. In order to know how crucial solar energy is it
Okay. So you’re considering going solar in your home but not before really weighing the pros and cons. The great thing is, between all the environmental benefits and multiple ways to finance your system, as long as your home is suitable for solar there really are no disadvantages.
Recently, the price of unrenewable energy resource such as oil, coral and natural gas is increasing by time because of rare and more and more usage for individual and industries. Solar panels which use energy from Sun are considered as renewable energy through the form of solar radiation, UV. Solar technologies are broadly characterized as either passive solar or active solar depending on the way they
In the last decades energy consumption has come to a time where people started noticing the climate changes and the effect of fossil fuel energy for not only being environmentally destructive, but also causing Global warming (the warming that occurs as a result of increase emissions of greenhouse gases) has become a very big issue worldwide. The fossil fuels (Oil, Coal, and Natural Gas) which is the main sources of the world’s energy sources, is also one of the main causes of the climate change. In addition with some human activities (e.g. through burning fossil fuels), they have contributed immensely to the global warming, which has also affected the climate conditions in the world. The affect of these changes has prompted some people to propose alternative energy like solar panels. According to Abby Gruen, after realizing the issues, the engineers at Bell Laboratories come up with the first useful photovoltaic cell, an alternative to fossil fuel energy but less harmful for the environment and the pocket. Solar panel which uses renewable energy like the sun to light homes heat and produces electricity. Unlike fossil fuel, solar panels is less harmful for the environment. Since it creation few decades ego, just recently solar panel started getting popular in homes in the United States and around the world. When it was invented people were not interested about it, because of the high installation price, however the price has changed dramatically since then. Even though
I am certain that all have heard of the terms green house gases, fossil fuels, and global warming. Have you ever questioned what will happen if nothing is done about the environmental problems facing the world today? What if I answer you that, we can merely use the power from the sun to power up our entire planet without the use of harmful energy sources, which affect our atmosphere? The power from the sun is what we call solar power. Solar power is the energy that comes from the sun as light and heat energy, and then it is later converted into electrical energy through solar panels (Nelson, 2008). This kind of power is completely free, right? Why should we put a lot of expense on other sources of energy, when there is a complete free
Solar cell or photovoltaic (PV) systems usually transformed energy from the sun in to electric current. It can be measured in terms of ‘‘conversion efficiency’’, the proportion of solar energy transformed to electricity. (Henderson, Conkling, & Roberts, 2007) Sunpower primarily focused on the production of solar cell. But by moving in to wafer manufacturing it soon incorporated in to manufacturing of solar power module units. In general Sunpower manufacturing process needed approximately two times as many steps as the usual solar manufacturing process need and many of these steps were distinctive to Sunpower. Sunpower has nearly 15 -20 established cell manufactures, a handful of silicon – based cell manufacturing upstarts and a number of thin film solar companies offering potentially unsettling technologies.
Solar energy is an eco-friendly alternative to fossil fuels. Our planet has been experiencing an average increase in global temperatures. Slowly but surely our planet is deteriorating, unless we change our form of energy into a greener alternative. Deterioration of our planet may occur at a faster rate. The depletion of fossil fuels is detrimental to our environment. By substituting fossil fuels with the solar energy, our planet will benefit. These benefits include: reduced climate change, beneficial economic opportunities on both a large scale benefitting our government and on a smaller scale helping individuals decrease their energy bills, and solar energy is renewable and sustainable.
Solar energy is the most plentiful and purist renewable energy source available. Because it is completely natural, it is considered to be a clean energy source. It does not disrupt the environment or threaten the Eco-systems the way oil and some other energy sources tend to. Nor does it cause greenhouse gases, air or water pollution. Solar energy is an immensely important aspect of life and has been since the beginning of time. Increasingly, we are learning how to harness this important resource and use it to replace traditional energy sources. Modern technology can utilize this energy in a variety of ways, such as; generating electricity, providing light or a comfortable interior environment, and heating water for domestic, industrial, or commercial use. One day solar energy may well become our primary form of energy. This would lead to a clean environment, less money spent on utilities, and a healthier world. It is highly important because it has the potential to allow technology and nature to co-exist peacefully.
Solar energy and its use isn’t new to the world. It has been used by various societies beginning from 7thCentury B.C, when the sun’s heat was concentrated by glass and mirrors to light fires. Today, we have everything from solar-powered buildings to solar-powered vehicles. By and large solar technology has some environmental, economic, psychological and ethical implications for our society. Actions taken by companies and individuals to increase the use of solar technology will create good local jobs, improve our environment and reduce our dependence on foreign oil while doing what’s ethical and moral for our society.
