The solar‐to‐electric power‐conversion efficiency ( η ) of dye‐sensitized solar cells can be greatly enhanced by integrating a mesoporous, nanoparticle‐based, 1D photonic crystal as a coherent scattering layer in the device. The photogenerated current is greatly improved without altering the open‐circuit voltage of the cell, while keeping the transparency of the cell intact. Improved average η values between 15% and 30% are attained.
