Recent progress on quantum dot intermediate band solar cells

Yoshitaka Okada, Katsuhisa Yoshida, Yasushi Shoji, Tomah Sogabe

Abstract

In order to surpass the thermodynamic Shockley-Queisser limit of energy conversion efficiency of single-junction solar cells, advanced concepts using multi-junction tandem structure and quantum nanostructure are presently under intense research. Recent developments and future research opportunities in high-efficiency photovoltaics technology based on quantum dot superlattice are reviewed.
