The emerging solution-based solar cells and photodetectors have gained worldwide research interest over the past decades. Hole transport materials (HTMs) have greatly advanced the progress of these solution-based electronics. Nevertheless, developing low-cost and efficient HTMs is far from satisfactory. In this contribution, poly(3-pentylthiophene) (P3PT) is introduced as a facile, low-cost, and versatile dopant-free polymer HTM for both quantum dot (QD) and perovskite electronic devices. Compared to the broadly used poly(3-hexylthiophene), P3PT presents the reduced molecular aggregation and preferential face-on orientation, which can markedly enhance the hole-carrier transport in optoelectronic devices. Accordingly, P3PT can deliver the substantial improvement of photovoltaic performance from ∼8.6% to ∼9.5% for QD/polythiophene solar cells and from ∼16% to ∼18.8% for perovskite/polythiophene solar cells, which are both among the topmost values in the corresponding fields. Furthermore, P3PT HTMs can also significantly enhance the photodetection performance of QD and perovskite photodetectors by a factor of ∼3, indicating its great application potential in a variety of emerging optoelectronics.

用无掺杂聚噻吩空穴传输材料构建高性能太阳能电池和光电探测器
过去几十年来，新兴的基于溶液的太阳能电池和光电探测器引起了全世界的研究兴趣。空穴传输材料（HTM）极大地推动了这些基于溶液的电子学的进步。然而，开发低成本、高效的 HTM 还远远不能令人满意。在这篇文章中，聚（3-戊基噻吩）（P3PT）作为一种简便、低成本且通用的无掺杂聚合物 HTM 被引入，用于量子点（QD）和钙钛矿电子器件。与广泛使用的聚(3-己基噻吩)相比，P3PT具有减少的分子聚集和优先的面取向，可以显着增强光电器件中的空穴载流子传输。因此，P3PT 可以将 QD/聚噻吩太阳能电池的光伏性能从 ∼8.6% 提高到 ∼9.5%，将钙钛矿/聚噻吩太阳能电池的光伏性能从 ∼16% 提高到 ∼18.8%，这两者都是该领域最高值之一。相应的字段。此外，P3PT HTM 还可以将 QD 和钙钛矿光电探测器的光电探测性能显着提高约 3 倍，表明其在各种新兴光电子学中的巨大应用潜力。
