As known, the search for abundant and renewable energy sources is one of the most ambitious technological objectives.

Currently, 85% of the total energy consumed on Earth comes from fossil fuels, with the well-known consequences on global warming and human health. The search for alternative energy sources has therefore become a necessity. Sunlight is the most economical, most evenly distributed, abundant and renewable energy source on Earth.

Device, for the conversion of solar energy, able to generate current from a transparent polymeric panel containing luminescent silicon nanostructures in red or near infrared (NIR).

- nanostructures based on a single intrinsic semiconductor, silicon

- high visibility transparency and excellent colour rendering index

- simplicity of the nano material encapsulation process and compatibility with the polymerization process

- low toxicity of the material used and ease of production of the photoactive material

- high availability of silicon in the earth's crust
