Printed solar cells for every device

Perovskites have excellent properties: They absorb light particularly efficiently and are good at conducting the generated electricity. Until now, however, perovskite-based solar cells were neither stable nor durable enough for large-scale use. Verma therefore spent five years at Empa developing printing processes for perovskite solar cells before setting up his own company in 2020. The Empa spin-off is currently on the road to success: Perovskia Solar supplies over 25 international companies with customized solar cells for the IoT and for consumer electronics devices. The company recently set up a factory in Aubonne in the canton of Vaud. One million perovskite elements are to be printed there every year to equip electronic devices with solar cells that supply our digital lifestyle with electricity.
