Polymer Solar Cells: High‐Performance Polymer Solar Cells Based on a Wide‐Bandgap Polymer Containing Pyrrolo[3,4‐ f]benzotriazole‐5,7‐dione with a Power Conversion Efficiency of 8.63% (Adv. Sci. 9/2016)

Abstract

In article 1600032, an efficient new wide‐bandgap polymer based on a novel moiety of pyrrolo[3,4‐ f]benzotriazole‐5,7‐dione (TZBI) is developed by Lei Ying, Feng Lui, Thomas P. Russel, Fei Huang, and co‐workers. The new chemistry enables fine electronic structure tuning and solution‐processed single‐junction polymer solar cells provided a remarkable power conversion efficiency of 8.63%. Full electrical and structural characterization reveales that TZBI is a promising building block for the application in highly efficient organic photovoltaics.
