Charging of printed Lithium-Ion-Battery by perovskite solar cell

In order to create fully independent product without need for any external charger and external connectors, the battery is connected with a state-of-the-art perovskite module which has enough output voltage for charging the battery outside and also at indoor light conditions. The perovskite module is built onto flexible PET substrate and has round shape in order to be compatible for integrated with all other elements of the final product. In picture below, the processing steps, top and cross-section views and electrical performance are demonstrated of flexible PSC module created for BEWELL project at IMEC.
