Abstract: A perovskite-based photovoltaic cell (or solar cell) wherein the perovskite photoactive layer includes at least one partially neutralized polyacrylic acid in an amount greater than or equal to 3% by weight, preferably between 4% by weight and 15% by weight, more preferably between 4.5% by weight and 12% by weight, with respect to the total weight of the perovskite precursors. The perovskite-based photovoltaic cell (or solar cell) can be advantageously used in various applications which require the production of electricity through the exploitation of light energy, in particular of solar radiation energy such as, for example: architecturally integrated photovoltaic systems (Building Integrated Photo Voltaic—BIPV); photovoltaic windows; greenhouses; photo-bioreactors; noise barriers; lighting engineering; design; advertising; automobile industry. The perovskite-based photovoltaic cell (or solar cell) can be used both in stand-alone mode and in modular systems.
