Organic solar cells (OSCs) are one of the most promising emerging photovoltaic technologies due to the rapid increase in efficiency in recent years. While efficiencies over 20% have been reported in laboratory scale devices using the conventional (p-i-n) structure, OSCs with inverted (n-i-p) structures still underperform, reaching values around 18%. Tin oxide (SnO) has recently emerged as a promising transport layer for OSCs. Yet, some reproducibility challenges shown by the literature have hindered the full adaptation of this electron transport layer (ETL) by the organic solar cell community. This Perspective evaluates the current status of investigation for SnO as the transport layer for OSCs, focusing on its integration into state-of-the-art systems and highlighting the challenges toward its implementation. We examine which strategies lead to the most efficient and stable devices using SnO and give a critical view of whether this material can soon become the next benchmark electron transport layer for OSCs.
由于近年来效率的快速提高，有机太阳能电池（OSC）是最有前途的新兴光伏技术之一。虽然使用传统（p-i-n）结构的实验室规模器件已报道效率超过20%，但具有倒置（n-i-p）结构的有机太阳能电池性能仍较差，效率约为18%。氧化锡（SnO）最近已成为有机太阳能电池一种有前途的传输层。然而，文献中显示的一些可重复性挑战阻碍了有机太阳能电池领域对这种电子传输层（ETL）的全面采用。本观点文章评估了将SnO用作有机太阳能电池传输层的研究现状，重点关注其集成到先进系统中的情况，并突出其实施面临的挑战。我们研究了哪些策略能使用SnO制造出效率最高且最稳定的器件，并对这种材料能否很快成为有机太阳能电池的下一个基准电子传输层给出批判性观点。
