A semi-transparent perovskite-based photovoltaic cell (or solar cell), wherein the photoactive perovskite layer includes at least one polysaccharide-based inert polymer in an amount ranging between 0.5% by weight and 3.5% by weight, preferably ranging between 1% by weight and 3% by weight, more preferably ranging between 1.5% by weight and 2.8% by weight, with respect to the total weight of the perovskite precursors. The semi-transparent perovskite-based photovoltaic cell (or solar cell) can be advantageously used in various applications that require the production of electricity through the exploitation of light energy, in particular solar radiation energy such as, for example: building integrated photovoltaic (BIPV) systems; photovoltaic windows; greenhouses; photo-bioreactors; noise barriers; lighting; design; advertising; automotive industry. Said semi-transparent perovskite-based photovoltaic cell (or solar cell) can be used either in a 'stand alone' mode or in modular systems.

Process for the preparation of stable nitroxyl radicals (I) starting from N-benzylphthalimide in two steps. In the first step, the intermediate N-benzyl-1,1,3,3-tetra-alkylisoindoline is prepared by treatment with a Grignard reagent, prepared in methyl-tert-butyl ether, of N-benzylphthalimide, obtained in the same reaction environment starting from phthalic anhydride and benzylamine. In the second step, the N-benzyl-1,1,3,3-tetra-alkylisoindoline is transformed into the nitroxyl radical by hydrogenolysis and subsequent oxidation with hydrogen peroxide in the presence of a catalyst selected from acids and salts of polymolybdic or polytungstic acids.
