A high‐performance organic photovoltaic heterojunction based on the triplet material, 2,3,7,8,12,13,17,18‐octaethyl‐21 H ,23 H ‐porphineplatinum( II ) (PtOEP), is demonstrated and 2.1 % energy‐conversion efficiency obtained (see Figure). As the exciton diffusion length might be extended greatly, triplet materials have great potential for use in organic and polymer solar cells.
