- 1Three-layer perovskite solar cell hits 30.1% efficiency▼Smoother perovskite films lift three-layer solar cell efficiency to 30.1%
Researchers report that making perovskite films smoother has pushed a three-layer, or tandem, solar cell to a power conversion efficiency of 30.1%. Reducing surface roughness in the perovskite layer helps the stacked cell convert more sunlight into electricity, a level approaching the performance of top commercial silicon technology and a step forward for next-generation photovoltaics.
- 2UK study finds silicon solar cells could slash satellite power costs▼UK study says silicon solar cells could cut satellite power costs by up to 90%
A UK study has found that silicon solar cells, a cheaper and more mature technology than the specialist cells currently used in space, could reduce satellite power costs by up to 90%. The finding points to silicon as a viable alternative for powering satellites, potentially lowering the cost of space missions.
