Over the past decade, the power conversion efficiencies (PCEs) of single-junction perovskite solar cells (PSCs) have improved dramatically to reach 25.7%, gradually approaching their efficiency limit. To surpass the theoretically predicted values for single-junction solar cells, constructing multi-junction (tandem) solar cells (TSCs) is a promising route to more efficiently utilize solar energy with lower thermalization loss to potentially achieve a PCE >40%. Among various kinds of tandem cells, the perovskite-organic TSCs (PO-TSCs) are fascinating because they take advantage of the complementary properties between organic solar cells (OSCs) and PSCs. They hold great promise to surpass existing TSCs regarding device performance, manufacturing cost, and potential applications. Very recently, the advent of Y6-series non-fullerene acceptors (NFAs) has ignited the vigorous progress of OSCs to enable an unprecedented advancement for PO-TSCs. In this perspective, the need of transitioning from single-junction to tandem solar cells is elucidated first, followed by providing a thorough comparison among the mainstream perovskite-based multi-junction solar cells. Then, the most pressing topics in perovskite/organic sub-cells and PO-TSCs are discussed, including phase segregation, structure-property-performance relationship, energy loss, interconnecting layers (ICLs), and long-term stability. In the end, perspectives on the core aspects related to the future development of PO-TSCs are provided.

钙钛矿-有机串联太阳能电池的前景与挑战

在过去十年中,单结钙钛矿太阳能电池 (PSC) 的功率转换效率 (PCE) 已大幅提高,达到 25.7%,逐渐接近其效率极限。为了超越单结太阳能电池的理论预测值,构建多结(串联)太阳能电池(TSC)是一种有前途的途径,可以更有效地利用太阳能并降低热化损失,从而有可能实现 PCE >40%。在各种串联电池中,钙钛矿-有机 TSC (PO-TSC) 令人着迷,因为它们利用了有机太阳能电池 (OSC) 和 PSC 之间的互补特性。它们有望在器件性能、制造成本和潜在应用方面超越现有的 TSC。最近,Y6 系列非富勒烯受体 (NFA) 的出现点燃了 OSC 的蓬勃发展,使 PO-TSC 取得了前所未有的进步。从这个角度来看,首先阐明了从单结太阳能电池过渡到串联太阳能电池的必要性,然后对主流的基于钙钛矿的多结太阳能电池进行了全面比较。然后,讨论了钙钛矿/有机亚电池和 PO-TSC 中最紧迫的话题,包括相分离、结构-性能-性能关系、能量损失、互连层 (ICL) 和长期稳定性。最后,提供了与 PO-TSC 未来发展相关的核心方面的观点。首先阐明了从单结太阳能电池过渡到串联太阳能电池的必要性,然后对主流的基于钙钛矿的多结太阳能电池进行了全面比较。然后,讨论了钙钛矿/有机亚电池和 PO-TSC 中最紧迫的话题,包括相分离、结构-性能-性能关系、能量损失、互连层 (ICL) 和长期稳定性。最后,提供了与 PO-TSC 未来发展相关的核心方面的观点。首先阐明了从单结太阳能电池过渡到串联太阳能电池的必要性,然后对主流的基于钙钛矿的多结太阳能电池进行了全面比较。然后,讨论了钙钛矿/有机亚电池和 PO-TSC 中最紧迫的话题,包括相分离、结构-性能-性能关系、能量损失、互连层 (ICL) 和长期稳定性。最后,提供了与 PO-TSC 未来发展相关的核心方面的观点。结构-性能-性能关系、能量损失、互连层 (ICL) 和长期稳定性。最后,提供了与 PO-TSC 未来发展相关的核心方面的观点。结构-性能-性能关系、能量损失、互连层 (ICL) 和长期稳定性。最后,提供了与 PO-TSC 未来发展相关的核心方面的观点。
