Back in 2009, a research team from the University of Tokyo led by Professor Tsutomu Miyasaka found that a substance called perovskite had the potential to generate solar power. However, at the time it only had a very weak power conversion efficiency (PCE) of about four percent and would break down in just a few minutes.
Because of these sizable flaws, not could practical use could be made of perovskite and the discovery lay dormant for a few years. Then, after a Korean team managed to double the PCE in 2011, research into the material was reignited. Now as scientists around the world continue to work on it, the PCE has become well above 20 percent and comparable with the standard silicon-based solar panels that we see today.
With perovskite being drastically cheaper to produce, more flexible to use, and now as efficient as regular solar panels, could we be on the verge of a solar energy revolution?
