Solution-processible conductive organics for efficient polymer and perovskite solar cells

Abstract

Thin-film solar cells made with polymer and perovskite absorbers represent a transformative technology with great potentials for high-throughput manufacturing at very low cost. Efforts in the design, processing, and engineering of π-conjugated molecule and polymers have enabled significantly enhanced performance and stability of such organic and hybrid electronic devices, through which the light-harvest, exciton dissociation, charge transport, and charge collection at the metal/absorber/metal oxide interfaces can be controlled and tuned [1, 2]. In this talk, the integrative molecular engineering approach conducted in group of combining interface [3], active material [4], and transparent electrode [5, 6] to improve the performance and stability of polymer and hybrid perovskite photovoltaic cells will be discussed. Specific emphasis will be placed on the development of solution-processible conductive organics via a mild n-doping process and their application for interface engineering between semiconductor and electrode interface for developing high-performance and flexible polymer and perovskite hybrid solar cells [8, 9].
