摘要: AbstractA new class of hole‐transport materials (HTMs) based on the bimesitylene core designed for mesoporous perovskite solar cells is introduced. Devices fabricated using two of these derivatives yield higher open‐circuit voltage values than the commonly used spiro‐OMeTAD. Power conversion efficiency (PCE) values of up to 12.11 % are obtained in perovskite‐based devices using these new HTMs. The stability of the device made using the highest performing HTM (P1) is improved compared with spiro‐OMeTAD as evidenced through long‐term stability tests over 1000 h. 出版者: Wiley 出版日期: 2016-01-15 出處: ChemSusChem, 2016-01, Vol.9 (3), p.274-279 識別號: ISSN: 1864-5631 識別號: DOI: 10.1002/cssc.201501392
