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更大，表面陷阱态减少，稳定性提高。因此，该方法制备的钙钛矿太阳能电池的功率转换效率可达21.5%，在平面法向结构中最高填充系数为83.4%。此外，与标准太阳能电池相比，热吸收和连续光吸收也有了很大的提高。这项工作已于今年成功发表在ACS Applied materials & Interfaces杂志上。另一项用于回收金属电极和减少贵金属材料消耗的纳米多孔Au膜电极钙钛矿太阳能电池的工作已于今年成功发表在《高级科学》杂志上。此外，对钙钛矿-热电混合器件的组装和性能表征也进行了尝试，但由于热电模块具有碳过膜的条件，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.
