Satellite-observed changes of surface spectral reflectances due to solar farming and the implication for radiation budget

Environmental Research Letters, 2020
Increased deployment of solar farms in the last decade is coincident with continued monitoring of surface spectral reflectances by the moderate resolution imaging spectroradiometers (MODIS) aboard NASA Aqua satellite.

Choice of Solar Spectral Irradiance Model for Current and Future Remote Sensing Satellite Missions

Remote Sensing, 2023
The accuracy of surface reflectance estimation for satellite sensors using radiance-based calibrations can depend significantly on the choice of solar spectral irradiance (or solar spectrum) model used for atmospheric correction.

Enhancement of reflectance reduction of solar cells by a silicon nanoparticle layer on a textured silicon substrate

Results in Optics, 2022
To reduce the surface reflectance of Si solar cells, a structure has been developed in which a silicon nanoparticle (SiNP) layer is formed on a pyramid-like structure to simultaneously exploit multiple reflections and refractive index changes.
