Current trends in high-efficiency III–V nanostructured solar cells

Summary form only given. On-going challenges in the solar energy conversion using quantum nanostructured solar cells are reviewed. In quantum dot intermediate band solar cells (QD-IBSCs), control of carrier dynamics with a particular emphasis on the two-step inter-subband absorption/recombination processes is paramount to achieving high-efficiencies. Significant efforts and a rapid progress have been made in the device physics as well as practical demonstration of high-efficiency IBSC using QDs.
