One of the grand challenges facing humankind is related to energy, its generation and storage being among the key issues of modern society, which is highly dependent on mobility. Therefore, next generation of energy production and storage systems are being developed based on advanced, environmental friendly and multifunctional materials. BCMaterials specifically focus on the conversion between solar energy, and chemical energy in applications such as perovskite and kesterite based solar cells. Other research activities include the development of energy harvesting systems, mainly based on mechanoelectric (piezoelectric and triboelectric) and thermo-electric systems for self-power and wearable sensors. Finally, new active materials are being developed for Li and Na- batteries, as well as new approaches for solid electrolytes and printable batteries.
