An organic hybrid planar‐mixed molecular heterojunction photovoltaic cell, whose photoactive region consists of a mixed layer of donor and acceptor molecules sandwiched between homogeneous donor and acceptor layers, is demonstrated. A power conversion efficiency of (5.0 ± 0.3) % under 1 sun AM1.5G solar illumination is achieved. The cell exhibits a low resistance to charge transport and a high exciton‐diffusion efficiency.
