The Opto-Electronic Physics Which Just Broke the Efficiency Record in Solar Cells
If you have a question about this talk, please contact Leona Hope-Coles.
There are new physical ideas emerging in solar cells. Improvements in Open Circuit Voltage, have now led to new records. At these high performance levels, the electron-hole transport is adequate. The critical issue becomes—management of the photons inside the solar cell. Counter-intuitively, efficient external fluorescence is a necessity for approaching the ultimate performance limits. This has led to the mantra: “A great Solar Cell also needs to be a great Light Emitting Diode”. Alta Devices Inc., has reached 28.8% in a thin-film flat plate cell. The single-crystal thin film technology that achieved these high efficiencies, is created by epitaxial liftoff, and can be produced at cost well below the other thin film solar technologies.
