Just read “Perovskite solar cell reaches record efficiency”. There have been lots of articles lately about the miracles achieved with Perovskite.
By The Way
At least this article mentions:
- “[P]erovskite based materials are water soluble which is a serious concern for solar cells that will be exposed to the elements.”
- “Also, there is the problem of scaling, the cells being tested were just 0.1cm2.”
- “And then there is the well known issue of hysteresis, where the material sometimes appears to change when first exposed to sunlight, causing a drop in efficiency. ”
