Indian scientists design lead-free perovskite solar cell with 23.61% efficiency
Developed through bandgap engineering and material design, the proposed PV device relies on a tin-based perovskite material known as CsSnI3-xBrx. It can reportedly be further designed to achieve power conversion efficiencies exceeding 24%.
Navigating the future of hydrogen
Hydrogen, often lauded as a beacon of hope in the quest for a low-carbon future, stands at a pivotal crossroads. As the world grapples with the dual challenges of escalating energy demands and climate change, hydrogen presents a unique opportunity to harmonize industrial development with environmental stewardship. However, its path is fraught with complexities and obstacles that require careful navigation.

NREL interactive chart of solar cell efficiency now including ‘hybrid tandems’
The new cell category includes perovskite/silicon, perovskite/CIGS, III-V/silicon and perovskite/organic tandem PV devices. It will list the absolute record efficiency for all-perovskite, two-terminal tandems regardless of the number of junctions.
New water circulation tech promises lower PERC solar cell manufacturing costs
A German team developed models to illustrate water-saving potential in PERC silicon solar cell manufacturing based on a circular approach and commercially available technology. In the case of a 5 GW fab, water savings of up to 79% and wastewater discharge reductions up to 84% could be achieved, a “significant” improvement compared to a reference scenario.
