Aiko Co., Ltd., a China-based PV leader, has partnered with the Australian Advanced Photovoltaic Center (ACAP) at the University of New South Wales to develop innovative photon multiplication technology for crystalline silicon cells. This advancement aims to push monocrystalline silicon cell efficiency beyond its theoretical limits, potentially exceeding 30% conversion efficiency. According to Aiko, this technology enables high-energy photons to generate additional low-energy photons, producing more electron-hole pairs for increased current without modifying cell structures. Aiko claims the technology aligns well with its existing BC cell manufacturing, facilitating smooth integration and making mass production viable. The partnership, witnessed by Aiko’s Chairman Chen Gang and ACAP’s founder Martin Green, addresses the PV sector’s urgent efficiency constraints, as alternatives like perovskite cells face durability issues.
