Abstract

Abstract : We investigate the dual use of tris(8-hydroxyquinolinato)aluminium, known as Alq3, as selective contact for electrons and, moreover, as fluorescence emitting layer to increase the photocurrent of perovskite solar cells. Abstract : We investigated the use of tris(8-hydroxyquinolinato)aluminium, known as Alq3, as a selective contact for electrons in functional FAMAPIBr (formamidinium/methylammonium lead iodide bromide) solar cells. The solar cells with Alq3 interfacial layers show excellent photocurrent upon standard 1 sun illumination (100 mW cm −2 @1.5 AM G sun simulated light) due to efficient energy transfer from the selective contact layer to the perovskite.
