The results show that the optical efficiency of the collector is reduced by 12% when using a cover; however, because the loss coefficient is reduced by 53%, the covered collector performs better when there is a large
Precise knowledge of the optical properties of the components used in the solar field of concentrating solar thermal power plants is primordial to ensure their optimum power production. Those properties are measured and evaluated by different techniques and equipment, in laboratory conditions and/or in the field. Standards for such measurements
An optical profile projector projects a light source onto a part. This beam of light either passes through the test piece or reflects off it, creating a big shadow or image on the screen. The resulting image is then compared against a standard or measured with the aid of reticles, grids, or a digital readout.
NIST''s PV characterization laboratory is used to measure the electrical performance and opto-electronic properties of solar cells and modules.
Together with slope errors provides a complete description of surface for predicting optical performance. How does it work? What is the output? How does this tool fit in the "toolbox?"

To solve the problem of underwater power supply, Xu group first proposed a solar panel-based receiver system in 2018, which was able to serve the dual purpose of optical communication and energy transfer in a UWOC system [99]. They set up an experimental system using the 405 nm LD as the transmitter and the off-the-shelf solar panel as the detector.
