Abstract
A solar cell comprisies a photovoltaic material and at least one polymer layer. In a further embodiment, a first polymer layer is electrically coupled to the photovoltaic material and has a high density of defects to facilitate hole transfer, and a second layer is electrically coupled to the first polymer layer and has a low density of defect states to facilitate hole transport. In another embodiment, a p-type polymer layer is electrically coupled to the photovoltaic material, and is configured to have a reduced lattice reorganization energy by modification of the polymer lattice
