Job Description

Currently, commercial photovoltaics are majorly single-junction devices that incorporate only one layer of absorber material. Limited thermodynamically in their maximum performances by the Shockley-Queisser (SQ) limit, a typical Si absorber with a bandgap of 1.12 eV cannot surpass power conversion efficiency of 30%. In order to harness more of the solar spectrum and overcome this fundamental limit, many research efforts have been devoted to multi-junction applications.

In multi-junction applications, two or more absorbers are coupled in bandgaps such that they can complementarily harvest specific parts of the solar spectrum, and hence overcome the efficiency limitations opposed by the SQ limit. In the past decade, the emergence of photovoltaic perovskites has sparked particular research interest in this area. As this novel class of crystalline absorber benefits from (I) high single-junction efficiencies as well as (II) exceptional ease of band-gap tuning, it is an ideal candidate for tandem or multi-junction devices. 



This project aims to develop a highly efficient and stable all-perovskite tandem solar cell. The candidate(s) will have the opportunity to develop hands-on experience in the lab, ultimately fabricating both high and low bandgap perovskite absorbers and implementing these in a tandem configuration.

At the end of this project, the candidate will obtain critical know-how on all perovskite tandem solar cells and their full fabrication at world-class facilities, with the additional opportunity of contributing their scientific findings to a peer-reviewed manuscript.
