Outline of Final Research Achievements |
In recent years, lead-based perovskites have become the most promising photovoltaic material showing an excellent photoelectronic performance. However, the lead-based perovskite has the issues of instability and environmental problem. In this project, we carried out the studies of improvement of the stability by using carbon electrode to replace Au and sprio hole transfer material. We also designed and synthesized several new lead-free Bi-based double perovskite materials. We investigated the crystallite and electronic structure and optical properties by various testing methods. The Bi-based Pb-free perovskite solar cells were also fabricated. The performance have been evaluated by J-V curves and IPCE. Based on the results, we published 20 papers(during them, 18 publications are collaboration with abroad). We also presented our results at international conferences as invited speaker and oral presentaion. We think that these results are very important for PSCs.
