Transparent photovoltaics are garnering significant interest for power generation in applications where light transmission is required. Metal halide perovskites have emerged as one of the most lucrative material classes such device architectures due to their exceptional optoelectronic properties, and compositional versatility enabling a wide range transparency levels. While research has primarily focused on semitransparent solar cell architectures, colored appearance, efficiency limitations hinder practical applicability. In this perspective, we look at semiopaque perovskite cells an alternative technological approach that comprises partially covered surfaces enable transmission. Our comparative analysis reveals devices potential superior efficiencies while maintaining color-neutral appearance. These benefits met with number hurdles, which provide key areas future innovation see realization real world applications.

Improving the Stability of Wide Bandgap Perovskites: Mechanisms, Strategies, and Applications in Tandem Solar Cells

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 7, 2025

Abstract Tandem solar cells (TSCs) based on wide bandgap (WBG) perovskites have gained significant attention for their higher power conversion efficiency (PCE) compared to single‐junction cells. The role of WBG perovskite (PSCs) as the sub‐cell in tandem consists absorbing high‐energy photons and producing open‐circuit voltages ( V OC ). However, PSCs face serious phase separation issues, resulting poor long‐term stability substantial loss TSCs. In response, researchers developed a range strategies mitigate these challenges, showing promising progress, comprehensive review is expected. this review, we discuss mechanism organic–inorganic hybrids all‐inorganic perovskites.
