摘要

A high open circuit voltage (V_OC) close to 1.4 V under AM 1.5, 100 mW cm^-2 conditions is achieved when carbon nanotubes (CNTs) are used as a hole conductor in methyl ammonium lead bromide (MAPbBr₃) perovskite solar cells. Time-resolved photoluminescence and impedance spectroscopy investigations suggest that the observed high V_OC is a result of the better charge extraction and lower recombination of the CNT hole conductor. Tandem solar cells with all perovskite absorbers are demonstrated with a MAPbBr₃/CNT top cell and a MAPbI₃ bottom cell, achieving a V_OC of 2.24 V in series connection. The semitransparent and high voltage MAPbBr₃/CNT solar cells show great potential for applications in solar cell windows, tandem solar cells and solar driven water splitting.
