Amsterdam, Noord-Holland - Offer Description Work Activities In this project you will contribute to realization of solar cells with a photovoltaic power conversion efficiency that can ultimately exceed 40%. It is focused on tandem solar cells, which are composed of two semiconductors that are stacked on top of each other, in which the top cell catches the blue/green part of the solar spectrum and the bottom cell the red/infrared part. We make use of an exciting new class of semiconductors, halide perovskites, that can... be deposited as ultrathin films. In this way either perovskite/silicon or perovskite/perovskite tandem solar cells are be made. The optimization of the efficiency of these tandem solar cells requires careful optimization of the distribution of light over the two subcells. Light absorption in a perovskite top cell is determined by a tradeoff between carrier collection (requiring a thin cell) and light absorption (requiring a thick cell). Moreover, the spectral distribution between the top and bottom cells... - Temporary - Full-time Amsterdam, Noord-Holland - Offer Description Work Activities In this project you will contribute to realization of solar cells with a photovoltaic power conversion efficiency that can ultimately exceed 40%.
