The Effect Of Solar Energy On Silicon Solar Cell Technology

Imagine this: rivers flooding towns, fires spreading across millions of acres, and hurricanes hitting the coastlines. This might be familiar since this all occurred in 2017. Humans are the greatest contributor to global warming and it has no sign of slowing down. What will our children or grandchildren be left with? Is there still time to fix what we have done? The short answer is no. What we can do is help slow down global warming and give future generations a better world to live in by using green technologies like solar power. Some may argue that green technologies such as solar panels pollute the earth but when compared to gas or coal, a solar panels negative effect on the environment is very minuscule. Solar panels are consistently getting better with breakthroughs of innovation. Solar panels are also a huge bonus to have with real estate and can be even more beneficial in certain states. Another thing they can give the consumer other than electricity is money! Solar panels are literally out of this world when it comes to outer space and how it contributes to new discoveries. Another form of solar power that has proven to be effective is called solar thermal systems. There are two types of solar thermal systems, solar thermal, and concentrated solar power.

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.

also cost effective. Los Angeles, California is the best place ideal for the two energy

California has many kinds of energy sources and have reserved abundant energy sources that help our day to day life experiences. Some industries in California use solar energy and/or coal energy as source energy to support their business. Solar energy is a reliable energy source and at the same time Coal energy also efficient energy source. The California state strongly advice to use solar energy in order to get efficient and reliable sources. However, producing and using coal energy has negative impacts, solar energy is more proficient, coast wise is cheap, and most of all we will keep our environment clean.

In this communications, PEDOT: PPS electrode is employed as a counter electrode in a dye-sensitized solar cell for low-cost photosensor applications. TiO2 nanomaterial is used as photoanode. The structure of the PEDOT: PPS film was investigated by atomic force microscope. This DSSC behaves like Schottky diode at the dark condition. The photovoltaic behavior was studied in the light intensity range 5 - 130 mW/cm-2. This cell has a stable fill factor of about 0.5 for all the studied illumination intensity range. The linear photo-response of the current suggests that new designed DSSC with the polymeric counter electrode is a promising device for the low-cost photosensor. The cell shows capacitance inversion from positive to

The Spirit Buses operate beginning approximately at 7:00AM to 12:00AM on Monday through Fridays and from 9:00AM to 5:00PM on Saturdays and Sundays (Transit). According to the “Facts and Questions” page found on the Aggie Transportation website, the buses run on diesel fuel, which is comprised of the fossil fuels that are draining every day. For daily operations, about 2,350 gallons of diesel fuel is used by these buses, each costing about $65.00 per hour to operate. Yearly, this calculates consuming 857,750 gallons of diesel fuel as well paying $45,552,000.00 for operation (Transit).

Bob Johnstone, author of Switching to Solar, proclaims that every day the sun produces 970 trillion kilowatt-hours of energy (Johnson 11). Volker Quaschning – writer of Understanding Renewable Energy Systems – puts this fact in perspective by explaining how the world only uses one ten-thousandth of that quantity to power itself (Quaschning 22). This means that if humanity can find a way to harness even a fraction of the sun’s energy, the world will no longer need fossil fuels or other harmful energy sources. There are, of course, many ways to translate the sun’s power into electricity, but one stands out. After analyzing the benefits and possible downfalls, it is clear that solar technology holds incredible potential. Not only is it pure

Over time plants have come up with possibly the most proficient power supply in the world. This power supply is known as photosynthesis. This is the transfer of sunlight, carbon dioxide and water into utilizable power, giving off oxygen along the way. When it comes to plants, usable fuel comes in the form of proteins, fats and carbohydrates. People, alternatively, are looking for liquid power in order to run things like cars and refrigerators. Scientists believe that trying to artificially recreate photosynthesis can be a way to solve the expensive and dwindling energy issues that society faces today (Layton, 2012).

If the current rate of consumption continues for oil, the planets entire oil supply is predicted to run out within the next 14 years. 21 years after that, our entire natural gas supply will run out. The reason is because the non-renewable resources we rely on are being used much faster then they can naturally be produced. As Peter Harper proposed, the problem of contemporary society can be stated succinctly: “We need to get (probably) 11 billion people through the transition complex to ‘Sustainia’, the sustainable state, before irreversible damage is done” (HARPER). The limited availability of non-renewable resources combined with the resulting pollution of obtaining and using non-renewable resources has sparked a movement towards renewable resources. These renewable energy sources, such as solar, wind, and hydropower, offer “green” alternatives to fossil fuels. The sun is our most powerful source of energy and can be used for a variety of processes. Even though solar technology only accounts for about 1% of the world’s energy consumption, solar technology has the potential to become a major contributor to the world’s energy consumption. Solar energy’s future importance can be found by the long-term threat of global climate change. Carbon dioxide emissions from the combustion of fossil fuels account for the largest amount of greenhouse gases that are causing our

Solar energy is experiencing a boom like no other. This year, it is forecasted to grow at an astonishing 119%, significantly higher than last year’s already impressive 17%. At the same time, expectations are for 14.5 gigawatts of solar power to be installed and surpass all others sources of new energy.

In our everyday life we use electricity without thinking how important it is to us. We use it to power our homes with gas, light, and heat. The bills we receive to keep this electricity could be easily reduced by looking at an energy source that gives our environment a clean and renewable energy source. This is a simpler, cheaper, cleaner, and all-around better energy solution known as solar energy. Solar energy is energy transformed from sunlight when the sun's rays hit the solar panels.The solar panels are made up of photovoltaic(PV) cells, which convert sunlight into direct current (DC) electricity throughout the day, thus providing living conditions while saving money and energy (Technology review). Solar energy is an efficient method of energy because it provides a clean energy source and it lowers the cost of electricity.

Discuss environmental impacts of power generation from fossil fuel, specially the impacts by coal-fired power plants.

Hybrid solar cells are the combination of two different compunds, where amorphous silicon cells combine with nano crystalline cells or with materials such as CIGS.These form the Hetrostructure between amorphous Si:H layer and C:Si wafer. Its efficiency is found to be around 21%.

As we all know, fossil fuel energy comes from wood and some organic materials from millions years ago. They experienced slow chemical process and became the coal and raw petroleum as we see today. However, since the first industry revolution, the speed of mining fossil materials and consuming all kinds of oil products has been accelerating in a geometric growth. People use coal to generated trains, and they use fuel to generated the majority of their engines, which includes cars, aircrafts, and heating machine. We have billions of people on earth right now, and everyone needs to consume energy for transportation, lightning and many fields in various ways. Where do the energy come from in the past three hundred years? Absolutely from the fossil material. But fossil energy is not unlimited, it has a maximum. When we consume it till the edge, then we have nothing to generate our machine. Luckily, solutions are always more than the problems. We create the way that is called renewable energy. It helps us retrieve energy from nature, like solar, wind, and water. These kinds of energy are unlimited, relatively, which means if the sun doesn’t fall down, the oceans aren’t dry, we can get power from them. However, even though it has a bright future, we still have many obstacles needed to be solved. (Hepbasli & Alsuhaibani 2011)

The energy content of solar radiation can be used as light, heat and electricity. This diversity means that solar power is an option different power systems important food worldwide. In fact, interest in solar power systems has been increasing in recent years worldwide. This interest to several factors, such as environmental awareness, effort should be to minimize the dependence on non -renewable fossil fuels countries and international agreements that require the reduction of greenhouse gases in the atmosphere of the earth. Heat storage technologies, systems and applications are studied in the field of solar energy. One way to collect and store solar energy by using solar ponds can be used to provide thermal energy for various applications, such as process and space heating, water desalination, refrigeration, drying and power generation. Thermal energy storage has always been the most important energy storage option. Solar ponds are a classic application of thermal energy storage and efficiency essentially depends on the storage capacity of the fluid, Thermo physical properties of pond conditions and surroundings. Recently, attention has been paid to friendly sources to the environment, sustainable energy, such as solar energy. In this respect, solar ponds seem to be a potential for the application method.
