The creation of solar energy requires little maintenance and solar electricity power plants produce zero emissions. Solar power plants use two different types of technologies: Concentrated solar power and Photovoltaic systems. Concentrated solar power plants, also known as “concentrated solar thermal”, uses solar thermal energy to make steam that is converted into electricity by a turbine. A photovoltaic system, also known as solar panels, generates electricity from sunlight. It is a device that converts light energy into electrical energy.
1954, three American researchers, Gerald Pearson, Calvin Fuller and Daryl Chapin, designed a silicon solar cell capable of a six percent energy conversion efficiency with direct sunlight
Introduction: The tradition solar cells have many faults and are dangerous to the environment. The TSC gives out a lot of pollution through its waste such as silicon tetrachloride. Also, when the reactors need to be cleaned several harmful greenhouse gases are used. The eye sensitized solar cells that are being designed in this lab are much cleaner for the environment. No waste is produced and no harmful gases are need to clean them.
Hybrid solar panels by Naked Energy where both photovoltaic and thermal energy outputs are combined. The benefit is reduced installation time and cost while maximizing the usable installation area . This would also include replacing the whole heating and water system. To ensure planning permission is approved the solar panels should not be easily visible from the street.

Si solar cells (SCs) are the most widespread energy conversion devices used to harvest solar energy. However, Si SCs do not respond to NIR light of over 1200 nm in wavelength in the solar spectrum owing to their
Wind power is regarded as a renewable energy source since wind is a clean, free, and is in abundant supply. The wind current can be used to generate electricity when it is harvested by wind turbines. Wind turbines are mounted on a tower to capture the greatest amount of energy. At 100 feet or more above the ground, the tower allows the turbine to take advantage of faster wind speeds found at higher altitudes. When the wind blows, the turbine’s blades spin clockwise and captures energy. As the wind turbines capture the wind’s power, it converts the kinetic energy of wind into mechanical or electrical energy, which can be used for power.
A solar cell is defined as energy of light being converted into electricity – they are most commonly known for being the driving force behind solar panels. Solar panel phone screens are a recent addition to possible technologies that promote prolonging battery life and conserving energy in mobile phones.
The science and technology behind wind power; the wind turbine is used to transform the kinetic energy from window into electrical energy that can be used in house holds. This is completed by the wind turbines pushing air between the blades of the turbine and rotating the blades, the kinetic energy of the air is transformed to the mechanical energy. Excess kinetic energy will be left in the wind as it travels away from the turbine. The mechanical energy is than transported to the generator from the shafts and gears in the wind turbine- this is the process of how the electrical energy is made. (Stelr,2017)
In 1954, Bell Laboratories have developed the first solar cell and the energy efficiency was 6% back then (Goetzberger et al. 2002). The figure has been raised to over 10% within 18 months (Green. 2009). For a long period of time, solar energy has mainly been applied into the power supply of space vehicles (Goetzberger et al. 2002). On account of the substantial development in the performance of silicon cells, the efficiency of solar energy conversion has reached 25% (Green. 2009). The growth over time of solar efficiency is delineated in Figure 1:
These types of systems may be powered by a PV array only, or may use wind, an engine-generator or utility power as an auxiliary power source in what is called a PV-hybrid system.
A hybrid vehicle is a vehicle that uses two or more distinct power sources to move the vehicle. The term most commonly refers to hybrid electric vehicles (HEVs), which combine an internal combustion engine and one or more electric motors. However other mechanisms to capture and utilize energy are included.
There are many forms of alternative energy sources that take the place of typical fossil fuels. One of the most common uses of these sources for eco houses is solar energy. Solar energy is when sunlight is converted into electricity for use, most commonly through solar panels. Solar panels are comprised of multiple photovoltaic cells, which absorb sunlight and transfer it into standard DC electricity. Photovoltaic cells are usually made of silicon, a semi-conductor (Roaf, 202). Solar panels are commonly installed on the roofs of houses where there is little blockage of the sun. Almost all eco houses employ solar energy as a main source because no waste is produced. Solar
A Silicon solar PV Cell is a device which is made up of semiconductor materials that produce electricity when exposed to light energy.  The doping process of a Silicon based PV Cell works by the photovoltaic material converting the light energy, photons, it absorbs into electrical energy. 
Solar cells are also known as photovoltaic cells, which suggest that light energy is being converted to electrical energy. Most photovoltaic cells consist of silicon in its crystalline structure. In that structure, each silicon atom has four valence electrons, and each one bonds to an adjacent electron. Silicon then is a poor conductor since electrons cannot move freely through the substance, but the addition of impurities such as phosphorus, which is called doping, to the silicon crystalline structure provide extra electrons called free carriers that can be knocked off the atom via light energy.6 The section of the photovoltaic cell that is doped with phosphorus is called the N-type because it has numerous negatively charged electrons flowing and creating a current. On the other hand, the section of the photovoltaic cell that is doped with boron is called the P-type because boron only has three valence electrons.7 When the N-type and
