二氧化鈦/奈米矽/非晶矽/ITO複合膜應用於太陽能電池之研究

A Study of the TiO2/nc-Si/α-Si: H Composite Film on ITO Glass Substrate for Solar Cell Applications

摘要


In this thesis, we developed a new structure of TiO2/nc-Si/α-Si/ITO/glass. TiO2 extends the solar absorption spectrum to UV range, and reduces the recombination probability of electron hole pair for its large energy gap (Eg>3.0eV). The nc-Si has nano size grain at surface, which induces a surface texture at both TiO2/nc-Si and TiO2/Al interface; consequently, scattering of injection photon happens at these textured interfaces to enhance the photon absorption in the active layer.
