SunPower Tops in Mono C-Si Solar Cell Efficiency: SunPower's Maxeon solar cells are currently the highest-effic...

The firm says it collated the numbers from public sources, including online product data sheets. All cells in this list are 156x156 in size. SunPower's Maxeon mono c-Si cells came out on top with 22.5 percent efficiency. Just this week the company said it has put into commercial production new 24 percent-efficient Maxeon solar cells, to be integrated into "select" 128-cell panels that exceed 20 percent efficiencies, and which will be "available in limited quantities" later this year. The upgraded cells reportedly offer low reverse-bias breakdown voltage to improve performance in shady and dusty conditions, and better temperature coefficient to increase energy harvest in hot environments. Panasonic (née Sanyo Electric), with its heterojunction with intrinsic thin layer (HIT) solar cells, ranks second in mono c-Si cell efficiency at 20.2 percent, just ahead of JA Solar at 20...
