Spiro-linked organic small molecules as hole transport materials for perovskite solar cells

Abstract

Organic–inorganic halide perovskite solar cells (PSCs) have attracted great attention as alternative renewable photovoltaic technology with power conversion efficiency (PCE) of >22%, which is on par with established technology. State of the art spiro-OMeTAD (2,2',7,7'-tetrakis-(N,N-di-p-methoxyphenyl-amine)-9,9'-spirobifluorene) is the most successful hole transport material (HTM) employed in PSCs. Recently, various types of spiro-linked organic small molecules have been reported to overcome disadvantages of spiro-OMeTAD, such as complex synthetic route, high synthetic cost, and require hygroscopic dopants to improve the charge carrier mobility and device performance, which significantly limits spiro-OMeTAD for large-scale application in the future. Herein, we provide an overview of recent developments in design, synthesis, and characterization of spiro-linked organic small molecules as hole transport materials (HTM) in pervoskite solar cells (PSC).
