Quality Control in the Perovskite Solar Revolution

Beyond Silicon: Quality Control in the Perovskite Solar Revolution

Depending on your age, you may have memories of sitting in class with a solarpowered calculator and covering the sensor until the display slowly faded mand finally died…only to come right back to life once you exposed it to light again. It was amazing!

 

Those little solar cells have gone through a few updates since then, and today they have become a not insignificant source of renewable energy for both businesses and homes. Globally, the solar sector went from generating 100TWh to 1000TWh during an 8-year period, an order-of-magnitude increase in less than a decade. But the jump from 1000TWh to 2000TWh then took only 3 years! (1) This has been driven by the obvious need for cleaner and renewable energies, but further catalyzed by a dramatic reduction in cost. In the late 1970’s a crystalline silicon cell was about $77 per watt, which then dropped to a mere $0.13 per watt in 2018 (2) That’s a pretty significant change.
