High-performance perovskite solar cells fabricated by vapor deposition with optimized PbI₂ precursor films

Abstract

High-performance CH3NH3PbI3 solar cells were achieved by hybrid physical–chemical vapor deposition (HPCVD) method with optimized spin coating process for PbI2 precursor films.

Organometal halide perovskite thin films and solar cells by vapor deposition

“…52 The lm morphology, thickness, stoichiometry, crystallinity as well as material purity have signicant impact on the overall solar cell performance. A variety of solution-and vapor-based OHP deposition techniques have been reported including one-step spin-coating, [53][54][55][56][57] two-step deposition techniques, 41,58-60 solventsolvent extraction, 61 vapor-assisted solution processes, [62][63][64][65][66][67][68][69] dualsource vacuum deposition, 4,5,[70][71][72][73][74][75][76][77] hybrid deposition, [78][79][80][81] hybrid chemical vapor deposition, [82][83][84][85][86][87] sequential vapor deposition, [88][89][90][91][92] ash evaporation, 93 etc. One-step spin-coating is one of the widely used methods because of its simplicity and low-cost.…”

Cadmium-doped flexible perovskite solar cells with a low-cost and low-temperature-processed CdS electron transport layer

“…10 A variety of methods including solution processing, 11,12 vacuum deposition [13][14][15][16] and vapor-assisted solution processing, [17][18][19] HCVD, 20 HPCVD, 21,22 LPVASP 23 etc. have been applied to fabricate perovskite lms.…”

Recent Advances in Synthesis and Properties of Hybrid Halide Perovskites for Photovoltaics

“…However, it is observed that the reaction kinetics need to be controlled and developed for consistent device performance and reproducibility. Thus, in view of these problems, vapor deposition [ 149 ], co-evaporation [ 150 – 152 ], electrodeposition [ 153 ], and hybrid deposition [ 154 , 155 ] techniques are much better in controlling the thickness and the reaction kinetics for the fabrication process of large-scale devices. Yang et al developed a CH 3 NH 3 I vapor-based approach for the deposition of perovskite layers in a nitrogen environment.…”
