Stable Sn-based Perovskite Solar Cells with high power conversion efficiency

Purpose and goal

The scientific purpose of this project is to develop environmentally friendly lead-free perovskites solar cells. Meanwhile, this project was proposed to broaden my knowledge through the exchange study at EPFL. In addition, we hope this project could enhance my academic network, presentation skills, knowledge transfer and leadership qualities, and thus promoting my academic carrier into a new stage.

Expected results and effects

We have achieved several significant scientific results, including increasing the efficiency of Sn-based perovskite solar cells by the post-treatment method and developing a new type of lead-free double perovskite (Cs2AgBiBr6) with excellent thermal and moisture stability. We have built new colorations with experts on different research fields, such as Prof. Anders Hagfeldt from Switzerland, Prof. David Cahen from Isreal, and Prof. Henk J. Bolink from Spain. Based on these achievements, I have been offered a new position as an assistant professor at Linköping University.

Planned approach and implementation

1.Widely discuss with experts on different fields to solve the difficulties in experiments. 2.Exchange study at EPFL to broad my knowledge on device fabrication. 3.Attend international conferences to build my academic network. 4.Deliver a course to PhD students to improve my presentation and knowledge transfer skills. 5.Guide graduate students to enhance my leadership qualities. 6.Attend the ’’From research to business’’ course to learn how to patent the scientific results.
