Design guidelines for periodic nanowire arrays in thin-film silicon/organic hybrid solar cell

In this work, we perform optical simulation and investigate the effect of the periodicity (P) and diameter (D) of SiNW arrays (SiNWs) on light harvesting in thin-film silicon/PEDOT:PSS hybrid solar cells. The hybrid cell structure comprises 2 μm thick silicon thin film with SiNWs textured surface and 50 nm thick PEDOT:PSS top layer. It is found that the light harvesting in the SiNWs is greatly enhanced compared to the planar counterpart.
