一种基于溶液的钝化方案，其特征在于使用分子碘和PbS胶体量子点（CQD）。改进的钝化转化为固体膜中更长的载流子扩散长度。这使得可以构建更厚的太阳能电池设备，同时保持有效的电荷收集，从而获得9.9%的认证功率转换效率，这是CQD太阳能电池的新纪录。
A solution-based passivation scheme is developed featuring the use of molecular iodine and PbS colloidal quantum dots (CQDs). The improved passivation translates into a longer carrier diffusion length in the solid film. This allows thicker solar-cell devices to be built while preserving efficient charge collection, leading to a certified power conversion efficiency of 9.9%, which is a new record in CQD solar cells.
