“Racing” Toward Perovskites – TL;DR

From CleanTechnica:

In a new paper published February 26 in the journal Nature Energy, a CU Boulder researcher and his international collaborators unveiled an innovative method to manufacture the new solar cells, known as perovskite cells, an achievement critical for the commercialization of what many consider the next generation of solar technology.

Here’s the TL;DR – No, perovskites are not dramatically closer to being commercially viable. They found they could reduce oxidation in open air (which is what kills the performance of perovskites over time) by mixing dimethylammonium formate with the perovskite solution before it’s sprayed onto the panel. This allows for retained performance of 90% after 700 hours, up from 300 hours. As the article notes, there are over 8000 hrs in a year.

Still have a ways to go.
