This isn't true. While it's correct that solar panels are less efficient at hot temperatures, this reduction is relatively small, and was not the main reason for firing up coal power stations.

The scientists explained that the high-temperature firing treatment currently in use as a post-deposition annealing step in the commercial production of screen-printed solar cells must be ...

A colossal solar flare has erupted and is set to trigger disruption to electrical systems and unusually widespread Northern Lights displays. The flare erupted yesterday in the middle of the Sun ...

Scientists in Germany have improved the efficiency of an industrial TOPCon solar cell from 23.8% to 24.1% by using laser-enhanced contact optimization as a post-firing treatment. The new process ...
