The main mechanism of most solar cells is that the light produces photogenerated electrons and holes, which are transferred to the electron transport layer and the hole transport layer (HTL), respectively. Then, these holes and electrons are transported to the anode and cathode, respectively, to generate electric current. Thus, charge transfer is a crucial process to fabricate efficient solar cells. Here, a fast vapor process is developed to fabricate SbSI and SbSI‐interlayered Sb₂S₃ solar cells by annealing an Sb₂S₃ film and SbI₃ powder in an inert gas atmosphere. The charge transfer of the vapor‐processed SbSI solar cells is increased by shortening the path length from SbSI to the HTL. This is achieved by an intimate contact between SbSI and the HTL, which is obtained by optimizing the morphology of SbSI, resulting in a record power conversion efficiency (PCE) of 3.62% in pure SbSI‐based solar cells under standard illumination at 100 mW cm⁻². In addition, the charge transfer of the SbSI‐interlayered Sb₂S₃ solar cells is enhanced by increasing the external driving force, an energetically favorable driving force provided by the TiO₂/Sb₂S₃/SbSI/HTM structure, and the best‐performing SbSI‐interlayered Sb₂S₃ solar cell exhibits a PCE of 6.08%.

通过增强的电荷转移实现基于锑的高效太阳能电池

大多数太阳能电池的主要机理是光产生光生电子和空穴，它们分别转移到电子传输层和空穴传输层（HTL）。然后，这些空穴和电子分别传输到阳极和阴极以产生电流。因此，电荷转移是制造高效太阳能电池的关键过程。在这里，通过对Sb ₂ S ₃薄膜和SbI ₃进行退火，开发了一种快速汽化工艺来制造SbSI和SbSI夹层的Sb ₂ S ₃太阳能电池。粉末在惰性气体气氛中。通过缩短从SbSI到HTL的路径长度，可以增加经过蒸汽处理的SbSI太阳能电池的电荷转移。这是通过使SbSI与HTL紧密接触而实现的，这是通过优化SbSI的形态来实现的，在100 mW cm的标准照明下，纯SbSI型太阳能电池的功率转换效率（PCE）达到了创纪录的3.62％⁻²。此外，通过增加外部驱动力，由TiO ₂ / Sb ₂ S ₃ / SbSI / HTM结构提供的能量上有利的驱动力以及最佳的结构，可以增强SbSI层间Sb ₂ S ₃太阳能电池的电荷转移。性能SbSI中间层Sb₂ S ₃太阳能电池的PCE为6.08％。
