In order to realize optimal quality of perovskite film for perovskite-thermoelectric hybrid device, the second solution-growth process has been employed to enhance the quality of perovskite films, resulting in a large crystal grain size, reducing surface trap states and improving stability. Therefore, the power conversion efficiency of perovskite solar cells fabricated by this approach has been promoted up to 21.5% with a highest fill factor of 83.4% in planar normal architecture. Moreover, the thermal and continuous light soaking have also been substantially promoted compared with those of standard solar cells. This work has been successfully published in the journal of ACS Applied Material & Interfaces in this year. Another work of nanoporous Au film electrode perovskite solar cells for recycling metal electrode and reducing noble metal materials consuming has been sucessfully publised in Advanced Science, in this year. Moreover, the studies of hybrid perovskite-thermoelectric hybrid device has been tried to assemble and characterize the performance, however, the studies have not been finised because of the condition of thermoelectric module with carbon past film.

为了获得最佳质量的钙钛矿-热电混合器件用钙钛矿薄膜，采用二次溶液生长工艺提高了钙钛矿薄膜的质量，使钙钛矿薄膜的晶粒尺寸变大，表面陷阱态减少，稳定性提高。因此，通过这种方法制造的钙钛矿太阳能电池的功率转换效率已提升至21.5%，在平面正常架构中最高填充因子为83.4%。此外，与标准太阳能电池相比，热浸渍和连续光浸渍也得到了显著提升。这项工作已成功发表在今年的ACS Applied Material & Interfaces杂志上。纳米多孔Au薄膜电极钙钛矿太阳能电池的另一项工作，回收金属电极和减少贵金属材料的消耗，已成功地在今年的先进科学。此外，人们也尝试了钙钛矿-热电混合器件的组装和性能表征，但由于碳糊膜热电组件的条件限制，这方面的研究尚未完成。
