Project
Multifunctional Energy Harvesting and Storage of Solar Energy with Halide Perovskites
The aim of my research is to build a device, which can simultaneously convert solar energy into charge carriers and act as a battery that saves those charge-carriers. This requires a multifunctional electrode composed of one or several materials. The outcome will be a fully integrated 2-electrode photobattery.
