The following submission statement was provided by /u/ForHidingSquirrels:

The key technology they’re seeking to develop are perovskite plus silicon tandem solar modules. I’ve read research suggesting this combination could reach up to 35% solar cells – meaning a 33’ish% solar module. Most solar panels today are about 20-22% efficient - reaching 33 - increase by about 50% - would probably drop the cost of solar electricity by 50% (different 50% numbers).
