In this paper, we present our route to fabricate Cu₂ZnSnSe₄ (CZTSe) thin films, which allows to achieve reproducible processing of kesterite absorber, that leads to efficiencies in the range of 10%. The article mainly focuses on the annealing process and demonstrates that controlling of the reactor pressure for selenization can be reliably used to tune the losses of volatile constituents in the absorber, enabling adjustments on the properties of the film and solar cell. The findings reveal a noteworthy resilience to small changes of the process parameters in the vicinity of optimum conditions. Interestingly, a certain pressure range for optimum Zn and Sn composition exists, which results in a broad and stable process window and enables reproducible processing of CZTSe with high power conversion efficiencies. The established process also allows simple upscaling of the device area and results in a power conversion efficiency of ≈ 8% on a large area of 2.85 cm². The highest efficiencies achieved by our process are around 11% for smaller lab scale devices.

CZTSe太阳能电池的弹性和可复制处理范围为10％

在本文中，我们介绍了制备Cu ₂ ZnSnSe _4的路线（CZTSe）薄膜，它可以实现可重复生产的硅藻土吸收剂，其效率在10％的范围内。本文主要关注退火过程，并证明控制硒化反应器压力可以可靠地用于调整吸收器中挥发性成分的损失，从而可以调节薄膜和太阳能电池的性能。研究结果表明，在最佳条件附近，工艺参数的细微变化具有显着的适应性。有趣的是，存在用于最佳Zn和Sn组成的特定压力范围，这导致宽而稳定的工艺范围，并能够以高功率转换效率对CZTSe进行可重现的加工。²。对于小型实验室规模的设备，我们的过程实现的最高效率约为11％。
