Buried Interface Engineering via an Ultrathin MACl Interlayer for Enhanced Crystallization and Performance of Wide‐Bandgap Perovskite Solar Cells

Weizhi Liu, Kaifu Qiu, Yawen Zhang, Beibei Zong et autres

Wide‐bandgap perovskites (WBGPVSK), as key top‐cell materials for tandem solar cells, are often limited by poor film crystallinity and interfacial defects. Herein, an ultrathin MACl interfacial layer is introduced between the hole transport layer and the perovskite in an inverted architecture to …

Non-competitive additives regulate molecular assembly for compact monolayers in perovskite/silicon tandems

Lirong Zeng, Bingyu Qi, Xin Zhang, Xinjiang Wang et autres

Achieving densely packed self-assembled monolayers (SAM) is essential for constructing well-defined functional interfaces, yet monolayer formation is often hindered by molecular aggregation and additive-induced competition for surface anchoring sites. Here we report a non-competitive additive strategy that regulates molecular assembly during SAM …

Particle decoration enables solution-processed perovskite integration with fully-textured silicon for efficient tandem solar cells

Naihe Liu, Gao Zhang, Wei Meng, Lijun Yang et autres

Perovskite/silicon tandem solar cells can exceed Shockley-Queisser limit, but achieving complete coverage of 2-4 μm pyramids on industrial fully-textured silicon with solution-processed perovskite film remains challenging. We address this issue by spray-coating alumina particles onto fully-textured silicon, creating a super-hydrophilic rough surface …

Iceberg-like pyramids in industrially textured silicon enabled 33% efficient perovskite-silicon tandem solar cells

Daoyong Zhang, Tom Wu, Biao Li, Degong Ding et autres

The pursuit of higher-efficiency solar cells has spurred the integration of perovskite materials with silicon-based technologies, yet achieving an efficient tandem architecture that leverages industrially textured silicon (ITS) with pyramid sizes larger than 2 μm remains a significant challenge. Such textured surfaces …

Low-Concentration Pyridine-Derived Molecular Passivation for Efficient Two-Step Assistance-Free Blade-Coated FAPbI3 Solar Cells

Jingcheng Xu, Shuo Ding, Xinjian Li, Zhuoyuan Kong et autres

The two-step blade-coating method exhibits several advantages such as simple operation and high reproducibility, making it a promising scalable deposition process for high-efficiency perovskite solar cells. However, a large number of defects exist at the interface, leading to nonradiative carrier recombination losses, …

Perovskite/silicon tandem solar cells: a comprehensive review of recent strategies and progress

Haocheng Wang, Wenjie Lin, Yongqiang Wang, Kaifu Qiu et autres

Abstract Perovskite/silicon tandem solar cells (PSTSCs) have garnered global interest owing to their potential for achieving high power conversion efficiencies (PCEs) at reduced costs. Although single-junction solar cells presently dominate the photovoltaic (PV) market, PSTSCs recently achieved a record-breaking PCE of 33.9%, …
