Inverse Opal Photonic Crystal Structured Bifacial-Iridescent Efficient Perovskite Solar Cells and Modules.

Colorful perovskite solar cells exhibit excellent potential for building-integrated photovoltaics (BIPVs), which increase the utilization of clean power. However, their efficiencies are lower than those of uncolored devices. Moreover, traditional mono-facial colored devices cannot satisfy diverse BIPV scenarios.
