China-based tier 1 PV manufacturer, Hareon Solar Technology said it presented two papers at the 39thIEEE Photovoltaic Specialists Conference (PVSC) last month that demonstrated new technological developments for both Passivated Emitter and Rear Cells (PERC) and Interdigitated Back Contact (IBC) solar cells.
Noting the complexity and higher costs associated with IBC cells over conventional c-Si cell designs, Hareon Solar noted that its IBC-based cell used a novel process to reduce costs, yet claimed a peak cell efficiency of 19.6%. IBC sells are expected to provide conversion efficiencies of over 24%.
Under the banner of its ‘Andes’ series (PERC) solar cell, which employed highly passivated rear surface to minimize losses were reported to have achieved batch average efficiency of 19.9%. Hareon Solar’s Andes cells were said to be in pilot production.
Modules using Andes cells were claimed to reach power levels up to 285W (60-cells) while modules with 72-cells were claimed to reach power levels of up to 335W.
Dr. Guoqiang Xing, CTO of Hareon Solar said, “Hareon Solar is committed to developing state of the art PV technologies to continuously improve performance and reduce cost of our products. The results presented at PVSC show that we are maintaining a leadership position in solar R&D.”
