6 FAQs about [Light-guiding solar cell]
How do solar cell windows work?
Incident light on the front face of the window is diffused and scattered at the front or rear surfaces of the window and guided to the solar cell arrays through the waveguide glass plates. Then, the solar cell arrays absorb the guided light to generate electric power.
How is a solar window constructed?
The waveguide plates consist of a diffuser and patterned glass, which scatters and guides the incident light to GaAs cell arrays at the window frame edges. These were designed and evaluated using the ray-tracing simulation method. We constructed and assembled the solar window using 3D printing.
How do luminescent solar concentrators work?
Luminescent solar concentrators absorb high-energy photons of shorter wavelengths in luminescent materials in a waveguide structure and radiate low-energy photons in all directions; among the re-emitted light, only the light emitted within a total internal reflection angle is guided into the cells at the edge of the waveguide , .
