Inolope Expo 2025

Perovskite solar cells are highly efficient and low cost in production. However, they still lack stability over the decades under real weather conditions. An international research collaboration led by Prof. Antonio Abate has now published a perspective on this topic in the journal Nature Reviews Materials. They explored the effects of multiple thermal cycles on microstructures and interactions between different layers of perovskite solar cells. They conclude that thermal stress is the decisive factor in the degradation of metal-halide perovskites. Based on this, they derive the most promising strategies to increase the long-term stability of perovskite solar cells.

Helmholtz-Zentrum Berlin and BAIP - Consulting Office for Building-Integrated Photovoltaics partner with Inolope Expo 2025 - the buisness platform for innovative building envelopes.

Visit us at booth 7.F02 to explore the present an the future of building-integrated photovoltaics. Learn how to create stunning, sustainable designs with solar architecture.

Combining two semiconductor thin films into a tandem solar cell can achieve high efficiencies with a minimal environmental footprint. Teams from HZB and Humboldt University Berlin have now presented a CIGS-perovskite tandem cell that sets a new world record with an efficiency of 24.6%, certified by the independent Fraunhofer Institute for Solar Energy Systems.
