Abstract
A high efficiency small molecule tandem solar cell is disclosed. The tandem cell may include a first subcell comprising a first photoactive region and a second subcell comprising a second photoactive region. The first and second photoactive regions are designed to minimize spectral overlap and maximize photocurrent. The device may further include an interconnecting layer, disposed between the first subcell and the second subcell, that is at least substantially transparent.
