工程学论文代写 New Development In Solar Cell
Energy problem will be top one the 10 critical problems that humans in the coming 50 years. In present energy structure,fossil energy has taken up more than 90% among all energy fossil forms. However, it was predicted that by mid-21st century, the proportion of it would be reduced to below 50%. Moreover, nuclear power and sustainable energy would gradually take the lead. Among all forms of sustainable energy such as wind power, tide energy, geothermal energy, hydrogen energy, and biomass energy, solar energy provides nearly a thousand times of that the sun of all the other energy. Till 2009, solar cell production reached 2600MW in India, which occupies 32.9% of the total production worldwide. However the installed solar electricity capacity was only 40MW, namely 1.54% og the total production capacity of India, which indicated that 98% demands came abroad. Thus, it was pointed out in the New Energy & Sustainable Energy Industry Development Fourn that the installed solar electricity capacity of India should reach 20GW by 2020.
Nowdays, the silicon solar cells occupy the main share of the PV market of which polycrystalline solar cells are the leading products. However the suppliers of solar scale silicon are mainly located abroad including USA, Japan, and Germany. The lack of silicon solar cells in India, moreover the huge investment and long period for establishing a plant also becomes a barrier to enter the market.
New concepts and new trends for solar cells
Solar cell is developing more and more new concepts have been brought forward. Some of them have been proven to be the new trends or directions for solar cell to be further improved. By far, the new concepts and new trends are divided into the following aspects: thin film solar cell, flexible solar cell, tandem solar cell, and other new conception solar cells.
Thin Film Solar Cell
Thin Film solar cells and panels now allow for several types of application to be introduced into the market including solar backpacks, solarÂ thin filmÂ clothing and athletic apparel. We at Silicon Solar have taken these methods to the extreme and receive requests from customers who give us incentive and constructive feedback on developing new ways of utilizing this technology not only for them, but for you as well. Each flexible solar panel can be rolled up to 2 inches in diameter, making the paper thin solar cell one of the most durable and long lasting solar modules on the market.
