Episode 9: Semi-transparent organic PV achieves dual function

MRS Bulletin Materials News Podcast

In this podcast episode, MRS Bulletin’s Laura Leay interviews Yang Yang and Yepin Zhao of the University of California, Los Angeles about a dual-function p-type soft interlayer they developed to enhance efficiency of charge transfer in organic solar cells. With the introduction of poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) as the p-type material, the researchers are able to improve the efficiency of the device as well as change its optical distribution. One goal for such a device, they say, is to create a greenhouse that generates its own electricity. This study is published in ACS Nano (doi:10.1021/acsnano.1c09018).
