Research Progress on Improving the Photovoltaic Performance of Polymer Solar Cells

摘要: Although polymer materials possess the advantages such as low cost and easy fabrication of flexible large-scale film for application in photovoltaic devices, performance polymer-based solar cells, especially energy conversion efficiency is inferior to their inorganic counterpart due shorter charge diffusion length caused by comparatively lower electric field between electrodes. This paper reviewed strategies improve properties mainly concentrated on modifying ameliorating device configuration. First, polythiophene (PT), poly(phenylene vinylene) (PPV), polyfullerene, other novel were introduced effective ways modify derivatives with more described detail, instance, copolymerization, incorporating additives dyes, etc. Furthermore, content configuration encompassed inverted architecture, tandem structure, introduction buffer layers, thermal annealing, integration optimized conditions. Finally, effects improvement methods concisely summarized, perspectives future research put forth.
