title: Highly efficient hybrid solar cells with tunable dipole at the donor-acceptor interface.
abstract: Effects of molecular dipole at the conjugated polymer-nanocrystal interface on the energy level alignment, the exciton dissociation process, and consequently the photovoltaic performance of poly[2,6-(4,4-bis-(2-ethylhexyl)-4H-cyclopenta[2,1-b;3,4-b']-dithiophene)-alt-4,7-(2,1,3-benzothiadiazole)] (PCPDTBT):CdSe quantum dot bulk heterojunction hybrid solar cells are systemically studied. Power conversion efficiency up to 4.0% is achieved when 4-fluorobenzenethiol is used for ligand exchange.
