China’s new solar cell design hits 33% efficiency with better durability

Chinese researchers developed a peak-targeted passivation method for textured silicon wafers using polystyrene nanospheres and aluminum oxide.

The approach helped a perovskite-silicon tandem solar cell reach about 33% efficiency.

The cell also showed strong durability, maintaining stability for 1,000 hours.

Because the method fits existing manufacturing lines, it could accelerate commercialization of next-generation solar panels.
