At the heart of a #dye_sensitized #solar_cell, lies a #mesoporous layer composed of #TiO2 nanoparticles with an average particle size of 20 nm, which is deposited on a piece of glass coated with a thin layer of #FTO.
Among various types of emerging #solar_cells, the ones based on #perovskite have been the fastest to reach higher efficiencies, holding great promise for facile and low-cost production of solar cells.
