The use of an ITO‐free MoO 3 /Ag/MoO 3 anode to control the photon harvesting in PCDTBT:PC 70 BM solar cells is proposed. At first sight, the fact that these anodes possess reduced far‐field transmission compared to ITO may seem to be a disadvantage. But, despite this, we show that by carefully tuning the resonant optical cavity we can enhance the external quantum efficiency close to the band edge of PCDTBT, resulting in high photocurrent and power conversion efficiency on par with ITO.
