Light management for ultrahigh-efficiency solar cells

Despite more than 50 years of research in photovoltaics, a complete understanding of the optimum flow of light in an ideal solar cell is still lacking. I will describe new nanostructured solar cell architectures for enhanced light trapping and concentration. The new designs can be made using modern large-area, thin-film and nanoimprint techniques. The presentation will focus on strategies to achieve inexpensive (thin-film) solar cells with efficiencies in the 15-30% range, as well as the steps required to raise the efficiency to 40% and beyond.
