Abstract
Photoactive compounds are disclosed. The disclosed compounds include a metal-complexed diketopyrrolopyrrole derived core with fused and/or pendant heterocyclic, heteroaromatic, or aromatic groups. The disclosed compounds exhibit relatively high vapor pressures to allow for purification and deposition of the compounds through thermal evaporation processes. The disclosed photoactive compounds can be used in organic photovoltaic devices, such as visibly transparent or opaque photovoltaic devices.
Claims18
A photovoltaic device comprising:
- a substrate;
- a first electrode coupled to the substrate;
- a second electrode above the first electrode;
- a first photoactive layer between the first electrode and the second electrode, wherein the first photoactive layer comprises a compound having the formula:
- wherein M is a metal, a metalloid, or a nonmetal coordinated to A,
- wherein A is F, C1, O, Ar, O—Ar, or CN,
- wherein Ar is an aromatic or fused aromatic ring or a heterocyclic ring containing N, S, or O, and wherein Ar has one or more substituents selected from H, a halogen, CN, CX3, wherein X is a halogen, or a straight, branched, or cyclic alkyl or alkylene group having a molecular weight of from 15 amu to 150 amu,
- wherein each Y1 is independently C(CN)2, O, S, or N—CN,
- wherein Z is C, N, C—CF3, or C—CN,
- wherein D1 is an aromatic or fused aromatic ring or a heterocyclic or fused heterocyclic ring containing N, S, or O, and wherein D1 has one or more substituents selected from H, a halogen, CN, CX3, or a straight, branched, or cyclic alkyl, alkylene, or alkoxy group having a molecular weight of from 15 amu to 150 amu, and
- wherein D2 is a nitrogen-containing heteroaromatic or heterocyclic ring or a fused heterocyclic ring containing N, S, Se, or O, and wherein D2 has one or more substituents selected from H, a halogen, CN, CX3, or a straight, branched, or cyclic alkyl, alkylene, or alkoxy group having a molecular weight of from 15 amu to 150 amu;
- and
- a second photoactive layer between the first electrode and the second electrode, wherein the second photoactive layer comprises a counterpart electron donor material or a counterpart electron acceptor material, and wherein the first photoactive layer and the second photoactive layer correspond to separate photoactive layers, partially mixed photoactive layers, or a fully mixed photoactive layer.
