SiNWs/PEDOT∶PSS杂化太阳电池的发展现状及问题研究

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

硅基太阳电池作为当前主流的光伏器件,进一步降低成本并提升效率仍是人们努力的方向。基于此,一方面,可以从太阳电池材料入手,用硅纳米线阵列代替平板硅,硅纳米线阵列具有优异的光学和电学性能,可大幅减少光反射,增加光的吸收和利用,有望提高光伏器件的效率,并可降低硅原料消耗,降低材料成本;另一方面,将硅微纳结构与有机材料进行复合,充分利用两种材料的优势,制备杂化太阳电池,以达到增强稳定性、提高效率和降低成本的目的。本文概括了Si纳米线阵列SiNWs/PEDOT∶PSS杂化太阳电池的发展现状和存在的问题,并针对相应问题的解决思路和发展方向进行了讨论。

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.
