New Tin-based Solar Cells Trap Heat 1,000 Times Longer, Could Beat 33% Limit
Could this push solar cell efficiency beyond the theoretical 33% limit? Interesting Engineering reports:

Researchers at the University of Groningen in the Netherlands found that tin-based perovskite solar cells can slow heat loss from high-energy “hot electrons…”

When sunlight strikes a panel, photons jump-start elect … ⌘ Read more
