About this collection

The breakthrough discovery of organometal halide perovskite materials as a superior converter to transform solar energy into electrical energy has completely changed the photovoltaic competition in the third-generation solar cells. In less than five years, the photovoltaic performance of perovskite-sensitized solar cells has reached over 15%. More intriguingly, the ambipolar transport property of organometal halide perovskite materials has been revealed, leading to the development of the simple planar heterojunction architecture perovskite solar cells with a high PCE close to 16%. To date, more and more scientists and engineers have been working on perovskite solar cells, greatly promoting the improvement of device efficiency as well as the understanding of this new star material for solar energy conversion. Due to these developments we would like to take this opportunity to launch this themed issue on perovskite solar cells.
