In recent years, researchers have been trying to create increasingly efficient solar technologies and more sustainable battery designs. Among emerging sustainable energy solutions are solar batteries, systems that can store the energy collected by solar cells or photovoltaic (PV) systems.
A research group at the Max Planck Institute for Solid State Research, supervised by Prof. Bettina Lotsch, recently introduced a sustainable integrated solar battery design based on materials that abundant on Earth. Their design, presented in a paper published in Energy & Environmental Science, is based on a bi-functional carbon nitride (K-PHI) photoanode that can both absorb light and store electric charge.
