Two-dimensional triphenylene cored hole-transporting materials for efficient perovskite solar cells. Issue 12 (17th January 2020) - Chen, Wangchao
Abstract : A PSC based on a two-dimensional triphenylene-cored HTM is unveiled that shows an optimal power conversion efficiency (PCE) of 19.4%. Abstract : Two organic hole-transporting materials comprising a two-dimensional triphenylene core and methoxyl-arylamine terminal units are developed and applied in perovskite solar cells. Enhanced photovoltaic and stability performance are obtained using TPH-T compared with those of spiro-OMeTAD.
