Progress in back contact crystalline silicon solar cell 

Dr. Seung Rim 

R&D Staff Engineer at SunPower Corporation 

Thursday, December 2, 4:15 PM, Nano Center 232 

Refreshments at 4PM 

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. 

About the speaker Seung Rim is a R&D staff engineer at SunPower Corporation. Prior to joining SunPower, he earned his B.S. in Electrical Engineering in Seoul National University in Republic of Korea and his Ph.D. in Electrical Engineering with Prof. Peter Peumans at Stanford University. His work currently focuses on high efficiency low cost back contact solar cell development.
