Scientists have developed a way to generate tiny amounts of solar energy at night. It’s true potential could be in space.

Scientists have developed a way to generate electricity from Earth’s radiant heat at night, potentially powering satellites even in darkness and opening new frontiers for space renewable energy.

Researchers at the Indian Institute of Technology Bombay have fabricated an inverted low-bandgap perovskite solar cell for applications in four-terminal (4T) perovskite-silicon tandem solar cells.
