Highly Efficient Organic/Inorganic Perovskite Photovoltaic-Thermoelectric Hybrid Device Study

为了实现钙钛矿-热电混合器件中钙钛矿薄膜的最佳质量，采用了二次固溶-生长工艺来提高钙钛矿薄膜的质量，从而得到了更大的晶体尺寸，减少了表面陷阱态，提高了稳定性。因此，用这种方法制备的钙钛矿太阳能电池的功率转换效率提高到21.5%，在平面正常结构中最高填充因子达到83.4%。此外，与标准太阳能电池相比，太阳能电池的热浸泡和连续浸光也有很大提高。这项工作已于今年在《美国计算机学会应用材料与接口》杂志上成功发表。用于回收金属电极和降低贵金属材料消耗的纳米金膜电极钙钛矿型太阳能电池的另一项工作已于今年在《高级科学》杂志上成功发表。此外，复合钙钛矿型热电混合器件的研究也一直在尝试组装和表征其性能，然而，由于碳纳米复合薄膜热电组件的条件限制，这方面的研究尚未完成。

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.
