Sunlight is the most economical, most evenly distributed, abundant and renewable energy source on Earth. The power of solar radiation that hits the surface of our planet is 10,000 times higher than the current global energy demand. In order to be usable, however, solar energy must be converted into forms that can be directly usable. One of the possibilities for converting solar energy into electricity currently being studied is linked to the use of luminescent solar concentrators.

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).

- plate with high chemical and photochemical stability

- simplicity of the nanomaterial production process

- high transparency in the visible

- excellent CRI index, therefore material with optical properties suitable to be used as a window
