Nanoscopic Characterization of Textured Substrate For Thin Film Solar Cells
This paper presents a nanoscopic characterization of a series of textured substrate for poly-Si thin film solar cells application performed by Atomic Force Microscopy (AFM), in order to find the optimum texture substrate and realize the light trapping. The relationship between average slopes (Tan q) and photovoltaics performance are studied based on the experimental results. The textured ZnO/Ag/SnO2/glass with Tan q of 0.08 yields the maximum conversion efficiency for Jsc and Voc. Although the poly-Si deposited on highly textured substrate (s>37 nm) shows excellence the light trapping properties, it tend to deteriorate the poly-Si (220) preferential growth and exhibits n-type character, yielding poor photovoltaic performances. In addition, changing optical reflectance and microstructure due to textured substrates are also discussed.
