SunPower Corporation designs, manufactures and delivers high-performance solar electric systems worldwide for residential, commercial and utility-scale power plant customers. SunPower high-efficiency solar cells and solar panels generate up to 50 percent more power than conventional solar technologies and have a uniquely attractive, all-black appearance. I'll briefly introduce SunPower's high efficiency products and market today. The advantages of SunPower's back contact solar panels will be discussed including high performance ratio (kWh/kWp) and reliability. In the second part of this talk, I'll present efficiency improvement of SunPower solar cells. The Generation 1 showed efficiency 20.5% and Generation 2 did higher than 22%. The Generation 3 product has been designed to deliver both increased performance and lower manufacturing cost. The champion cell achieved 24.2% of conversion efficiency by optimizing of the diffusion recombination on production equipment using a production wafer, 155.1cm2 n-type CZ.
