perovskite solar cells

Researchers report a new perovskite solar cell reaching 30.1% efficiency, achieved by engineering smarter perovskite layer structures to reduce energy losses. The result marks another step toward making perovskite-based panels competitive with, or better than, conventional silicon technology, and is drawing attention in the renewable energy field.

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.

SoFab Inks has received a $300,000 grant from the US National Science Foundation to develop lower-cost perovskite solar cell layers. The funding will support the company's work on ink-based manufacturing methods aimed at making perovskite solar panels cheaper to produce, a key step toward wider adoption of the emerging solar technology.
