Towards a CO2 neutral urban environment - cutting the wire

The project generated important knowledge about practical light measurements, but also an awareness of the need to characterise light and PV cells with varying spectral light distribution. To address this, the project developed a light logger unit capable of measuring the spectral distribution of visible light as well as total irradiation. The production price is estimated to be less than DKK 1,000. Furthermore, a test facility (test area 20 cm x 20 cm) to characterise PV cells exposed to light with varying spectral distribution for irradiation 0-200 W/m2 was constructed. This setup is modular, and easily upscaled. (Energy 10)
