Prospects for Tin-Containing Halide Perovskite Photovoltaics

Precision Chemistry, Journal Year: 2023, Volume and Issue: 1(2), P. 69 - 82

Published: April 13, 2023

Tin-containing metal halide perovskites have enormous potential as photovoltaics, both in narrow band gap mixed tin-lead materials for all-perovskite tandems and lead-free perovskites. The introduction of Sn(II), however, has significant effects on the solution chemistry, crystallization, defect states, other material properties In this perspective, we summarize main hurdles tin-containing highlight successful attempts made by community to overcome them. We discuss important research directions development these propose some approaches achieve a unified understanding Sn incorporation. particularly focus discussion charge carrier dynamics nonradiative losses at interfaces between perovskite extraction layers p-i-n cells. hope insights will aid accelerate high-performance, stable single-junction solar cells tandems.

Post‐Assembled Alkylphosphonic Acids for Efficient and Stable Inverted Perovskite Solar Cells

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: June 12, 2024

Abstract The self‐assembled monolayer (SAM) is now widely applied at the hole‐selective interface of efficient inverted perovskite solar cells (PSCs). However, voids are unavoidable in SAMs due to rough substrate and deposition conditions, which lead direct contact between active layer electrode, undermining efficiency stability PSCs. Here, alkylphosphonic acids with different alkyl chain length post‐assembled fill voids, thereby forming a compact po‐SAM layer. By further modifying head group acids, PSCs improved wetting passivation. Finally, formed by (2‐Bromoethyl) phosphonic acid [4‐(3,6‐dimethyl‐9H‐carbazol‐9‐yl)butyl] contributes champion device power conversion 25.16% (certified 24.67%) under operation or storage. This work demonstrates advantages improving performance PSCs, offering ideas for SAM modification.

Self-Assembled Monolayer-Based Hole-Transporting Materials for Perovskite Solar Cells

Nanomaterials, Journal Year: 2024, Volume and Issue: 14(2), P. 175 - 175

Published: Jan. 12, 2024

Ever since self-assembled monolayers (SAMs) were adopted as hole-transporting layers (HTL) for perovskite solar cells (PSCs), numerous SAMs HTL have been synthesized and reported. offer several unique advantages including relatively simple synthesis, straightforward molecular engineering, effective surface modification using small amounts of molecules, suitability large-area device fabrication. In this review, we discuss recent developments SAM-based materials (HTMs) PSCs. Notably, in article, HTMs categorized by similarity synthesis to provide general information building a SAM structure. are composed head, linker, anchoring groups, the selection groups is key design synthetic procedure HTMs. addition, working mechanism has visualized explained inspiration finding new head that not yet explored. Furthermore, both photovoltaic properties stabilities discussed summarized, expanding reader’s understanding relationship between structure performance SAMs-based
