Why Metal-Free Fullerene C60 is Crucial for Reaching the 33.33% Perovskite Efficiency Threshold

In the global race for clean energy, monolithic perovskite/silicon tandem solar cells (PSTSCs) have emerged as the most commercially promising technology to surpass the theoretical single-junction Shockley-Queisser efficiency limit of 29.4%. In May 2026, a groundbreaking research milestone redefined the…
