Status and research development of Si NWs/PEDOT∶PSS hybrid solar cells

At present, silicon-based solar cells are widely used, but their high cost and low efficiency limit the promotion of solar power generation still. To solve these problems, there are two approaches: first, use silicon nanowire arrays instead of planar silicon for reducing the reflection of light effectively, increasing light absorption and utilization because silicon nanowire arrays have excellent optical and electrical properties. second, using organic/inorganic hybrid solar cell materials for improving stability/efficiency and reducing costs. This paper summarized the status and the problems of the present Si NWs/PEDOT: PSS hybrid solar cells, and discussed the possible solutions and research areas.
