Controlling of doping in semiconducting light absorber can minimize the charge recombination and maximizing power output from solar cells; however, it is challenging for perovskites due to lack of controlled doping. Here, we report that a short post-annealing of less than 3 min for facilitating high-throughput manufacturing of perovskite solar modules in an ambient environment maintains the stoichiometric composition of perovskites, encouraging a spontaneous de-doping of perovskites during aging. The reduced self-doping results in less charge recombination and, thus, higher device efficiency. The stabilized open-circuit voltage of sub-cells in the CH₃NH₃PbI₃ minimodules with an area >20 cm² reaches 1.19 V on average. The aperture efficiency reaches 17.8% under one sun and 18.7% under a quarter sun illumination, deriving an averaged efficiency >20.0% for each sub-cell with an area >3 cm², demonstrating the excellent uniformity of the films by this scalable process. The minimodule also works as uniform light-emitting devices.

控制半导体光吸收剂中的掺杂可以最大程度地减少电荷复合，并使太阳能电池的输出功率最大化；然而，由于缺乏受控的掺杂，钙钛矿具有挑战性。在这里，我们报告说，为了便于在环境中高通量生产钙钛矿太阳能电池组件，短短的退火后不到3分钟即可保持钙钛矿的化学计量组成，从而促进了钙钛矿在老化过程中的自发去掺杂。减少的自掺杂导致较少的电荷复合，从而提高了器件效率。CH ₃ NH ₃ PbI ₃微型模块中面积> 20 cm ²的子电池的稳定开路电压平均达到1.19V。在一个太阳光下，孔径效率达到17.8％，在四分之一太阳光下，孔径效率达到18.7％，得出面积大于3 cm ^2的每个子电池的平均效率> 20.0％，这表明该可伸缩工艺的薄膜具有出色的均匀性。微型模块还可以用作均匀的发光设备。
