British rooftops could be hosting a breakthrough in new solar power technology by next summer, using a crystal first discovered more than 200 years ago to help harness more of the sun’s power.

An Oxford-based solar technology firm hopes by the end of the year to begin manufacturing the world’s most efficient solar panels, and become the first to sell them to the public within the next year.

Oxford PV claims that the next-generation solar panels will be able to generate almost a third more electricity than traditional silicon-based solar panels by coating the panels with a thin layer of a crystal material called perovskite.

The breakthrough would offer the first major step-change in solar power generation since the technology emerged in the 1950s, and could play a major role in helping to tackle the climate crisis by increasing clean energy.
