Molecular Design Strategies of Photovoltaic Materials for Polymer Solar Cells

摘要

Polymer solar cells(PSCs)are composed of a blend active layer of a p-type conjugated polymer(p-CP)as donor and an n-type organic semiconductor(n-OS)as acceptor,sandwiched between a transparent electrode and a metal electrode.The photovoltaic materials and devices of the PSCs have attracted great attention in recent years,due to their advantages of low-cost solution-processing,light weight,thin active layer,and capability to be fabricated into flexible and semitransparent devices.
