Abstract Hybrid tin‐lead (Sn‐Pb) perovskites have garnered increasing attention due to their crucial role in all‐perovskite tandem cells for surpassing the efficiency limit of single‐junction solar cells. However, easy oxidation Sn 2+ and fast crystallization Sn‐based perovskite present significant challenges achieving high‐quality hybrid Sn‐Pb films, thereby limiting device's performance stability. Herein, an all‐in‐one additive, 2‐amino‐3‐mercaptopropanoic acid hydrochloride (AMPH) is proposed, which can function as a reducing agent suppress formation 4+ throughout film preparation. Furthermore, strong binding between AMPH precursor significantly slows down process, resulting with enhanced crystallinity. The remaining its products within contribute improves resistance substantial reduction defect density, specifically vacancies. Benefiting from multifunctionalities AMPH, power conversion (PCE) 23.07% achieved narrow‐bandgap best‐performing monolithic cell also exhibits PCE 28.73% (certified 27.83%), among highest reported yet. devices retain over 85% initial efficiencies after 500 hours continuous operation at maximum point under one‐sun illumination.

Abstract Although perovskite solar cells (PSCs) demonstrate outstanding power conversion efficiency (PCE), their practical applications are still limited by stability issues caused various problems such as poor crystal quality triggered structural instability. Herein, to address the instability of perovskites, we introduced a polymer additive, poly-L-lysine hydrobromide (PLL), into precursor promote growth, thereby constructing stable structure. The results show that introduction PLL modulates colloidal aggregation state in solution, provides longer time for growth and successfully realizes formation large-sized films with high crystallinity. More importantly, owing its hydrophobic long-chain structure widespread distribution C=O NH on chain, firmly locks crystals, enhancing while blocking intrusion external factors water molecules, significantly enhances overall device. PLL-based PSC has negligible hysteresis PCE is improved from 22.20% 23.66%. PLL-modified devices excellent thermal environmental stability. These findings highlight promising additive optimizing crystallization, offering guidance fabricating efficient photovoltaic devices.

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.
