In principle, conjugated polymers can work as electron donors and thus as low-cost p-type organic semiconductors to transport holes in photovoltaic devices. With the booming interests in high-efficiency and low-cost solar cells to tackle global climate change and energy shortage, hole transporting materials (HTMs) based on conjugated polymers have received increasing attention in the past decade. In this perspective, recent advances in HTMs for a range of photovoltaic devices including dye-sensitized solar cells (DSSCs), perovskite solar cells (PSCs), and silicon (Si)/organic heterojunction solar cells (HSCs) are summarized and perspectives on their future development are also presented.

原则上，共轭聚合物可以充当电子给体，从而充当低成本的p型有机半导体，以传输光伏器件中的空穴。随着对解决全球气候变化和能源短缺的高效，低成本太阳能电池的兴趣日益浓厚，基于共轭聚合物的空穴传输材料（HTM）在过去十年中受到越来越多的关注。从这个角度出发，对包括染料敏化太阳能电池（DSSC），钙钛矿太阳能电池（PSC）和硅（Si）/有机异质结太阳能电池（HSC）在内的一系列光伏器件的HTM的最新进展进行了总结并对其观点进行了展望。还介绍了未来的发展。
