How to Fast-Track Perovskite Solar Cells

Cars That Think

When British solar manufacturer Oxford PV shipped the first commercial order of perovskite-silicon solar cells last September, it was touted as a breakthrough in the industry. But the lack of follow-on shipments since then serve d as a reminder t hat this te chnology wasn t quite ready for mass commercialization. 20 per watt.
