<p>In order to surpass the theoretical Shockley-Queisser limit of energy conversion efficiency of single-junction solar cells as well as to lower the cost, advanced concepts and new materials are emerging. By placing a dense array of quantum dots in the active region of a <i>pin</i> solar cell, which consequently leads to formation of a superlattice miniband or intermediate-band, the solar cell efficiency could reach 63% under full sunlight concentration. Recent status and future research opportunities are reviewed.</p>
