6 FAQs about [Light-chasing solar cell bracket efficiency]

How can a non-concentrating solar cell achieve high radiative efficiency?

Key to achieving the highest possible efficiencies with this design are the thin cell and the highly reflective, light trapping back reflector shown in the schematic. Here we consider a non-concentrating system with limited emission angle in a thin, light trapping GaAs solar cell with high radiative efficiency, as shown in Figure 1b.

Does angle restriction affect recombination in light trapping GaAs solar cells?

Effect of angle restriction in a light trapping GaAs cell. Detailed balance efficiencies as a function of maximum emission angle for various thickness light trapping GaAs solar cells with thick silicon nitride cladding. In panel a, all recombination is assumed to be radiative with an ideal back reflector.

How does direct sunlight affect solar cell efficiency?

Under direct sunlight, conventional solar cells emit light isotropically, while receiving light only from the angles spanned by the solar disk. This increase in the angular distribution of light increases the photon entropy, and the inherent entropy increase reduces the solar cell efficiency.

How can light trapping be achieved in silicon solar cells?

Another approach to achieve light trapping in silicon solar cells is the use of reflective external light-trapping structures with length scales larger than the involved wavelengths. Such structures can be modeled employing geometrical optics.

How does light affect a solar cell?

Light: Science & Applications 2 , e45 ( 2013) Cite this article In a conventional flat plate solar cell under direct sunlight, light is received from the solar disk, but is re-emitted isotropically. This isotropic emission corresponds to a significant entropy increase in the solar cell, with a corresponding drop in efficiency.

How can a monofacial solar cell avoid the escape of light?

One way to avoid the escape of light on the rear is by placing a mirror, which immediately doubles the path length and is done in almost all monofacial solar cells. But even doubling of the path length is not enough to achieve loss-free absorption, and rather, it is desirable to have light traveling under an angle to the surface.
