High-efficiency Perovskite Solar Cells

Details

Organic-inorganic hybrid perovskite solar cells have attracted significant research attention in the past years and are regarded as a promising candidate for next-generation photovoltaic technology. This unprecedented surge in device performance is a testament to the extent to which PSCs upended the scientific knowledge of solution-processed photovoltaic devices.  This remarkable success can largely be ascribed to a steadily improved device design, combined with optimization of the employed materials: from the first mesostructured configuration – a legacy of the evolution of PSCs from the work on dye-sensitized solar cells – to the planar thin-film design; and from the early methyl-ammonium lead iodide perovskite, to the quadruple-cation mixed-halide perovskite. 

Currently, KPV-LAB has focused on developing large-area compatible fabrication methods for high-performance solar cells using emerging hybrid perovskite material systems which include mixed cations and mixed halides.  We majorly work on precursor-process-structure-property-performance relationship for hybrid lead halide perovskites, then translate these lessons into scalable processes, such as vacuum evaporation, with the aim of achieving PCE > 20% and extended stability.
