Abstract

Abstract : Efficient and sustainable Buchwald-Hartwig amination enables the synthesis of new branched and polymeric HTL materials for perovskite solar cells with performances comparable with those of Spiro-OMeTAD. Abstract : Perovskite solar cells (PSCs) are experiencing tremendous interest due to compatibility with solution processing on a wide range of substrates and very high efficiency. The hole transport layer (HTL) plays a fundamental role in such multistack cells. We propose new branched and polymeric organic HTL derivatives with sustainable synthesis and performances exceeding those of Spiro-OMeTAD, the standard in the field.
