Porous One‐Dimensional Photonic Crystals Improve the Power‐Conversion Efficiency of Dye‐Sensitized Solar Cells

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. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
