the amorphous silicon thin film solar pv modules could be:
Advantage 1 : Accumulated more power
Lower temperature coefficient and better absorption to non-direct and weak light make amorphous silicon solar panel have accumulated more power generation in a certain period of time। The difference of power generation between Amorphous silicon and crystalline silicon solar panel will be larger in high temperature and overcast condition। Amorphous silicon Solar panel relatively outperforms the other technologies at high insolations because it is less sensitive to the higher temperatures found under intense lighting conditions। Amorphous silicon also have better spectral response to the wavelengths of overcast condition ,so it also outperforms others under this kind of low insolation conditions।
Advantage 2 : Low manufacturing cost
Fewer Sinicon usage and no limit material make amorphous silicon thin film solar panel have lower material cost. It is suitable to manufacture in large panel also further cut the manufacturing and material cost.
Advantage 3 : Shorter energy payback time
Energy pay back time means the time of the energy the solar panel produce to cover the energy it use to manufacture the solar panel. Solar panels, like every. Other product, do need energy for manufacturing. But solar panel pay back this energy input within1 to 3 years, depending on its type and location. During its expected lifetime of 30 years, the solar panel produces therefore 10 to 30 times the energy it originally consumed. In the figure below,Thin film solar panel have shorter energy pay back time compared to crystalline solar panel.
