Current Research

The main research activity of KV-LAB is focused on the development of high-efficiency solar cells, based on silicon wafers as currently crystalline silicon is the most important photovoltaic technology today with a global market share of about 90%. Towards this end, we focus on novel carrier-selective passivating contact schemes, dopant-free electron and hole contacts.
KPV-LAB aim to develop 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%. ​​​​​​
In KPV-LAB, we develop Perovskite-Silicon Tandem Solar Cells targeting efficiency beyond the single-junction limits of the silicon solar cells. Towards this end, we are developing optimal bandgap perovskite absorbers as well as minimizing the parasitic absorption losses originating from carrier selective contacts and transparent electrodes. We are exploiting thermal evaporation technique and hybrid techniques to fabricate perovskite solar cells on textured silicon solar cells and scaling up.​​​​​​​​
