A cell with known spectral response can be used as reference, replacing the irradiance sensor [1]. To measure spectral response of MJ solar cells, each junction needs to be characterized separately by light biasing (filtered light or variable intensity lasers) of the nonmeasured junctions and by...

We present an algorithm to calculate the azimuth and elevation angles for a dual axis tracker to be pointed away from the sun with a desired orientation between the sun and the tracker face. Desired tracker positions are specified in terms of angle of incidence (AOI) and AOI direction, i.e...
To cover the entire observation geometry of DPC, the simulation value of VZA is set to 0–70° with the step of 10°, the solar zenith angle (SZA) is set to 0–70° with the step of 10°, and the sun–satellite relative azimuth angle (RAA) is set to 0–180° with the step ...
Cloud shadows were defined as the intersection of the predicted cloud shadow area, derived from the cloud probability layer and the mean solar azimuth angle, and dark areas, identified as low-reflectance, near-infrared (NIR) pixels. To compensate for potential atmospheric contamination, we avoided ...
