Photovoltaic panel convex lens

What is a convex lens solar concentrator?

The two-lens system with convex lens as primary concentrator located 5 cm above the Fresnel lens secondary concentrator. The solar kit, with and without the convex lens attachment, was exposed to sunlight to test its output power by measuring its voltage, current, and temperature using a multimeter.

What is a convex lens system?

The lens system was designed so that the primary concentrator (in this case a convex lens) would be able to refract sunlight from non-perpendicular angles to the secondary concentrator (in this case a Fresnel lens), which would then focus the sunlight onto the solar cell.

Can convex lens be used as primary concentrator for multi-junction solar cells?

The use of convex lens as primary concentrator for multi-junction solar cells. Emergent Sci. 2018, 2, 5. [ Google Scholar] [ CrossRef] Tien, N.X.; Shin, S. A Novel Concentrator Photovoltaic (CPV) System with the Improvement of Irradiance Uniformity and the Capturing of Diffuse Solar Radiation. Appl. Sci. 2016, 6, 251.

What is a convex line-focus Fresnel lens?

Convex line-focus Fresnel lenses or dome-shaped Fresnel lenses of bifocal, or non-imaging type are more recently developed for collection of solar rays. Most of the research and development works have been directed at imaging systems and non-imaging systems which represent the future trends of solar concentration applications.

Can Fresnel lenses be used for building integrated photovoltaics?

Though imaging Fresnel lenses can be used as solar lighting elements , in buildings, non-imaging Fresnel lens concentrators is another choice for building integrated photovoltaics.

Do convex lenses produce more power?

The convex lens setup was tested with the Fresnel lens setup over a 3-day photoperiod by measuring the voltage, current, irradiance, and temperature at every hour. The results showed that the convex lens setup produced 1.94% more power, but only at around midday.
