All-perovskite tandem solar cells are regarded as the next generation of devices capable of enhancing the solar energy utilization rate. Unlike single-junction perovskite solar cells (PSCs), the efficacy of tandem cells is contingent upon the …
Self-assembled molecules (SAMs) have been widely employed as hole transport layers (HTLs) that can improve the power conversion efficiency (PCE) of perovskite solar cells (PSCs). However, few SAMs are effective for wide band gap (WBG; Eg = 1.77 eV) …
This study is on the enhancement of the efficiency of wide bandgap (FA0.8Cs0.2PbI1.8Br1.2) perovskite solar cells (PSCs) used as the top layer of the perovskite/perovskite tandem solar cell. Poly[bis(4-phenyl) (2,4,6-trimethylphenyl) amine] (PTAA) …
