Inorganic-organic Hybridperovskite as effizient Absorber in Photovoltaic Systems

Perovskite Solarcells

The conversion of solar power, the most abundant and clean form of energy, to electric energy is one of the most important tasks for researchers worldwide. Since 2009, when the organic-inorganic (hybrid) perovskite methylammonium lead iodide was used as absorber material in a solar cell for the first time, interest and development in the perovskite semiconductor increased rapidly. The optoelectronic properties, cheap and abundant starting materials, solution processability, and power conversion efficiencies close to the traditional silicon-based photovoltaics make lead-based perovskites an excellent material for low-cost photovoltaic devices.

Our studies focus on A-site modification for lead-based perovskites, interactions between solvents, precursors, additives, and their influence on the perovskite crystallization. Furthermore, we study perovskite solar cell fibers and wires, lead-free perovskite-type solar cells, and alternative inorganic electron-transporting materials.
