Solliance announced the demonstration of an industrially-applicable roll-to-roll process for the production of solar cells, achieving a record 12.6% conversion efficiency on cell level.   Perovskite microcrystals are a promising material to make high-yielding, thin-film solar cells. They can be processed into thin, light-weight and potentially semitransparent modules that could eventually be integrated in building materials such as windows or curved construction elements. Solliance and its res...
