Currently, the most powerful perovskite/silicon tandem solar cell is a 29.8% device that was recently developed by scientists at Helmholtz-Zentrum Berlin (HZB) in Germany.

While these are hopeful numbers, a few things are keeping solar power from kickstarting an energy revolution, chief among them being the industry’s reliance on non-renewable silicon.
