摘要
A photoactive layer for an organic photovoltaic device has a supramolecular assembly of donors or acceptors formed from a plurality of units that are mixed with electron acceptors or electron donors, respectively, to form an ordered or semi-ordered bulk heterojunction structure. Each unit is formed from a plurality of sub-units that are combined and ordered by hydrogen bonding or other non-covalent interactions to form units that by π-stacking and, optionally, other forces are organized into the supramolecular assembly. Each sub-unit includes at least one electron donor or acceptor moiety, at least one non-covalent interacting moiety, and a linking moiety between the non-covalent interacting moiety and the electron donor or electron acceptor moiety of the sub-unit. The organized supramolecular assembly connects donors or acceptors through the thickness of the photoactive layer, and allows parallel continuous electron acceptor or electron donor phases through the thickness of the active layer.
