碩士 === 正修科技大學 === 電機工程研究所 === 102 === In recent years,because solar power system,has the advantage of low environmental pollution,is currently recognized as the national development of renewable energy is the most important one. However, limited by the properties of semiconductor materials .Makes solar power generation efficiency is limited. Many studies, To effectively improve the efficiency of solar photovoltaic panels to generate electricity, Have to raise the majority of its solar energy, And to reduce the temperature of the main module, The stronger the solar energy concentrator module higher power generation efficiency, but also enhance the module temperature, however, the temperature is too high will make solar panels power efficiency. This study proposes two can effectively enhance the actual power generation efficiency of the method, first, the use of silver mirror scattering in the solar panel, as is the mining scattered way, you can not make the high temperature solar panels, power generation efficiency can be improved, and In addition, you can use silver mirror reflected light to affect the shading of the module, making the solar panels will not lead to reduced power generation efficiency and shadow, the second, the use of circulating water cooling system to lower the temperature, the solar panels on the back of brass devices, the use of water thermal solar panels take the temperature of the way to make solar panels the temperature decreases, the power generation efficiency can be improved, and finally the silver mirror combined with the cooling system to do, and to observe and analyze system capacity.
