Abstract

Recent advances in wide-bandgap (WBG) perovskite solar cells (PSCs) demonstrate a burgeoning potential to significantly enhance photovoltaic efficiencies beyond the Shockley–Queisser limit for single-junction cells. This review explores the multifaceted improvements in WBG PSCs, focusing on novel compositions, halide substitution strategies, and innovative device architectures. The substitution of iodine with bromine and organic ions such as FA and MA with Cs in the perovskite lattice is emphasized for its effectiveness in achieving higher open-circuit voltages and reduced thermalization losses. Furthermore, the integration of advanced charge transport layers and interface engineering techniques is discussed as critical to minimizing open-circuit voltage (V_OC) deficits and improving the photo-stability of these cells. The utilization of WBG PSCs in diverse applications such as semitransparent devices, indoor photovoltaics, and multijunction tandem devices is also explored, addressing both their current limitations and potential solutions. The review culminates in a comprehensive assessment of the current challenges impeding the industrial scale-up of WBG PSC technology and offers a perspective on future research directions aimed at realizing highly efficient and stable WBG PSCs for commercial photovoltaic applications.

宽禁带钙钛矿：近期发展和创新的综合综述

宽带隙钙钛矿太阳能电池（PSCs）的最新进展表明，在单结电池的Shockley-Queisser极限之外，显著提高光伏效率的潜力正在迅速增长。这篇综述探讨了WBG psc的多方面改进，重点是新的成分、卤化物替代策略和创新的器件架构。在钙钛矿晶格中，碘取代溴和有机离子（如FA和MA取代Cs）在获得更高开路电压和减少热化损失方面的有效性得到了强调。此外，还讨论了先进电荷传输层和界面工程技术的集成对于最小化开路电压（VOC）缺陷和提高这些电池的光稳定性至关重要。本文还探讨了WBG PSCs在各种应用中的应用，如半透明器件、室内光伏和多结串联器件，解决了它们目前的局限性和潜在的解决方案。该综述最后全面评估了当前阻碍WBG PSC技术工业规模扩大的挑战，并对未来的研究方向提出了展望，旨在实现用于商业光伏应用的高效稳定的WBG PSC。
