Journal ArticleDOI
Additive Enhanced Crystallization of Solution‐Processed Perovskite for Highly Efficient Planar‐Heterojunction Solar Cells
Po-Wei Liang,Chien-Yi Liao,Chien-Yi Liao,Chu-Chen Chueh,Fan Zuo,Spencer T. Williams,Xu-Kai Xin,Jiang-Jen Lin,Alex K.-Y. Jen +8 more
TL;DR: This work presents a probabilistic analysis of the chiral stationary phase transition of Na6(CO3)(SO4)2, a mixture of Na2CO3 and Na2SO4 which has shown promise as a raw material for high-performance liquid chromatography.
Journal ArticleDOI
Role of Chloride in the Morphological Evolution of Organo-Lead Halide Perovskite Thin Films
TL;DR: By employing the through-plane TEM analysis, this work gains detailed insight into the unique crystallographic textures, grain structures, and elemental distributions across the breadth of films grown from precursor solutions with different chemistries.
Journal ArticleDOI
Binary‐Metal Perovskites Toward High‐Performance Planar‐Heterojunction Hybrid Solar Cells
Fan Zuo,Spencer T. Williams,Po-Wei Liang,Chu-Chen Chueh,Chien-Yi Liao,Chien-Yi Liao,Alex K.-Y. Jen +6 more
TL;DR: A simple, low temperature solution process for Pb/Sn binary-metal perovskite planar-heterojunction solar cells is demonstrated, and the optimized device shows a PCE exceeding 10%, which is the best result for binary- metal perovSKite solar cells so far.
Journal ArticleDOI
The roles of alkyl halide additives in enhancing perovskite solar cell performance
TL;DR: In this paper, the additive can participate in the perovskite formation via dissociated halides, suggesting that molecular structure of alkyl halide additives plays multiple roles in modulating the dynamics of perovskiy crystal growth.
Journal ArticleDOI
High‐Performance Planar‐Heterojunction Solar Cells Based on Ternary Halide Large‐Band‐Gap Perovskites
Po-Wei Liang,Chu-Chen Chueh,Xu-Kai Xin,Fan Zuo,Spencer T. Williams,Chien-Yi Liao,Alex K.-Y. Jen +6 more
TL;DR: In this paper, the authors proposed to replace Pb 2+ with Sn 2+ cation, which has the tendency to oxidize to Sn 4+ and thus p-dope the perovskite, displaying metallike conductivity.
