Major breakthrough promises to increase energy output and accessibility.  When the first perovskite solar cells [PSCs] were introduced, the technology could offer 3.8% efficiency, far behind silicone alternatives, but with a far lower price point.  As research continued, the numbers improved, hitting 20% efficiency in recent years. Now a team at Oxford PV, a spin-off … Continue reading Game-changing perovskite solar cell blows roof off efficiency records
