Due to a combination of improved charged extraction and increased light absorption, a 120\% increase in the short-circuit current is achieved compared with that of conventional ZnO/QD devices. }, keywords = {2014, depletion region, lead selenide, p-i-n heterojunctions, quantum dot solar cells}, isbn = {0935-9648}, doi = {10.1002/adma.201401250}, author = {Ko, Dong-Kyun and Patrick R.
