Abstract
Halide perovskite materials have spread in solar cells and photodetectors because of their excellent possibilities for tuning their absorption wavelengths, ease of fabrication, and low carbon footprint. However, their main drawbacks are related to their short device lifetime and stability problems in addition to limited efficiency at certain wavelength. For this reason, in this letter, we design a metasurface that can be integrated into a particularly long-life, stable, and sustainable perovskite solar cell with the aim of enhancing its performance under indoor conditions. The metasurface has been designed and numerically simulated to enhance the halide perovskite response at the typical emission wavelengths of indoor LEDs. Adjusting the response of these solar cells to those specific spectral ranges by metasurfaces may create novel energy harvesting devices.
Key words: Perovskite solar cell / Nanostructured grating / Indoor energy harvesting / Pb-free / FDTD methods
