The Next Generation of Solar Energy | Perovskite Solar Cells

Perovskite solar cells are a remarkably cheap solar cell technology and have achieved remarkable growth since their inception a decade ago, sharply increasing in efficiency from 3.8% to 25.2%, near to their theoretical efficiency. Perovskite solar cells are a new technology and still needs to be scaled up for commercial applications, but perovskites have the potential to revolutionise the energy harvesting market, with cheap, high efficiency solar energy in the near future.
