Abstract
Perovskite solar cells are called to revolutionize the field of optoelectronic due to their intrinsic high absorption. Photonic structuration is widely reported as an efficient way to improve light harvesting. Nevertheless, little is known on the combination of photonic structuring and perovskite material. In this study, photonically-structured TiO2 is considered as photoanode layer for perovskite solar cells in a will to enhance light absorption through the excitation of quasi-guided modes within the photoactive perovskite material, while optimizing the charge collection and the global efficiency in the photovoltaic assemblies. Consequently, the photo-active layer is structured using opal-like perovskite layers (monolayers, bilayers or trilayers) made of perovskite (full or truncated) spheres, including hybrid uniform/structured layers, embedded in a TiO2 matrix. We present both numerical simulations and experimental results.
