Perovskite solar cells are an emerging photovoltaic technology that is gathering huge attention in the solar community for its power conversion efficiency. Recently, the coupling between the perovskite and the silicon technologies in the tandem configuration boosted even further this power conversion efficiency, reaching record values for terrestrial applications. However, several degradation mechanisms in the perovskite are negatively affecting the stability of this technology, questioning if successful commercialization is possible. At KPVLAB we are pioneering the outdoor testing of perovskite/silicon tandem solar cells to investigate, understand, and improve their stability.
