It’s been a few years since Tsutomu (Tom) Miyaskaya and Henry Snaith discovered that use of halide perovskites as a light harvester material in hybrid solar cells was possible. Once efficiencies higher than 15%, were achieved it started raising the attention of the photovoltaic industry. In November 2014, at the 6th World Conference on Photovoltaic Energy Conversion in Kyoto, Japan, the achievement of a single-junction perovskite solar cell with a power-conversion efficiency of 24% was mentioned.
But as a result investors, and all those concerned with the use of renewable energy, have brought some economic muscle to the deployment of the perovskites in the exciting future of photovoltaic energy conversion.
But how are the perovskites different from other solar cells? Here’s an video of a course by Henry Snaith of Oxford University that although a bit outdated explains some of the basics. And with the 1st International Conference on Perovskite Solar Cells and Optoelectronics coming up there’s no better way to get a handle on this technology.
