The object
Aihua Wang co-developed PERC and PERL crystalline-silicon solar-cell structures at UNSW. Rear-surface passivation and localized contacts reduce recombination losses in the physical cell, improving conversion efficiency and making the architecture a consequential building block in high-volume solar-module manufacturing.
01
What Aihua did
Co-developed high-efficiency crystalline-silicon PERC and PERL solar-cell structures.
02
Why it matters
QEPrize awarded its 2023 engineering prize to the four-person PERC team, citing the invention and development of the photovoltaic technology.
03
Living-status check
PV Tech interviewed Wang on February 5, 2024 about her new role as VSUN chief technology officer and her current high-efficiency cell work.
