2020年4月9日 · Hysteresis in perovskite solar cells is suppressed with the insertion of a phenyl-C61-butyric acid methyl ester (PCBM) layer. In situ PL imaging is employed to observe the ionic migration in the pero...

2021年9月1日 · In the present work, we investigated the effect of an external electric field on the PL intensity and decay of P3HT:PCBM mixture films using steady-state and time-resolved electrophotoluminescence (E-PL). An applied electric field enhanced the steady-state PL spectra of both pristine and mixture films.

2024年10月23日 · The resulting modified PCBM layer exhibits enhanced conductivity and electron mobility, significantly suppressing charge recombination.

2024年10月15日 · PCBM modulate the Fermi level of perovskite to form a band bending energy level. PCBM passivate the uncoordinated Pb 2+ to reduce the trap-state density in perovskite. The PCBM-modified PSC exhibits an impressive power conversion efficiency of 25.21%.

5 天之前 · The WF of PCBM represents a typically “Mark of Zorro”-type dependence on the WF of bare substrates, where the negative pinning energy (E ICT−) and positive pinning energy (E ICT+) for PCBM are 4.17 and 5.17 eV, respectively, which are comparable with the previous report [29], [30]. Hence, the UPS-derived energetics at the pristine and SAM ...

富勒烯衍生物由于其出色的电子提取能力而被广泛用于倒置钙钛矿太阳能电池。然而，[6,6]-苯基-c 61-丁酸甲酯 （pcbm） 在溶液中容易团聚，并表现出相对较低的电离势垒，增加了界面中的电荷复合损失和电荷积累。在这里，四甲基秋兰姆二硫化物 （tmds） 被引入 ...

2011年7月18日 · In the field of polymer-based photovoltaic cells, poly (3-hexylthiophene) (P3HT) and 1- (3-methoxycarbonyl)propyl-1-phenyl [6,6]C 61 (PCBM) are, to date, the most-studied active materials around the world for the bulk-heterojunction structure.

We propose a doping method by using [6,6]-phenyl-C 61 -butyric acid methyl ester (PCBM) to fill the grain boundary interstices of the methylammonium lead iodide (CH) perovskite for the elimination of pinholes. A sandwiched PCBM layer is also used between the perovskite and TiO layers to improve the interfacial contact.
