- 1Smoother perovskite films push triple-junction solar cells to 30.1% efficiency▼Smoother perovskite films lift three-layer solar cell efficiency to 30.1%
Researchers report that making perovskite films smoother has raised the efficiency of a three-layer, or triple-junction, solar cell to 30.1%, a new benchmark for this class of device. Reducing surface roughness helps the stacked layers convert more sunlight into electricity. The result fuels ongoing excitement about perovskite technology as a cheaper, potentially more efficient alternative to conventional silicon solar panels.
- 2Silicon solar cells could cut satellite power costs 90%, UK study finds●UK study says silicon solar cells could cut satellite power costs by up to 90%
A UK study concludes that silicon solar cells could reduce the cost of powering satellites by as much as 90% compared with current technologies. The finding suggests cheaper, more accessible photovoltaic materials could replace costly space-grade cells, potentially lowering the price of satellite missions and expanding access to orbit for smaller operators.
