Controlling the direction in which the perovskites are grown and removing defects through chemical passivation could ...

 
 

First invented in 2009, perovskite solar cells are improving at an astonishing rate, having already surpassed the 20 percent efficiency mark in the lab. A new finding at the Lawrence Berkeley National Laboratory could now reveal their full potential, approaching their theoretical efficiency limit of 31 percent – far better than commercially available panels.

It’s the line where water vapor gets far enough from the heat of the star to form ice crystals around dust particles, and we usually can’t see it, even with our most powerful telescopes. Thanks to one particular stellar outburst however, the line was pushed about 13 times farther out than usual, allowing the Atacama Large Millimeter/submillimeter Array (ALMA) to pick it up.
