6 FAQs about [High frequency heating method for obtaining silicon from photovoltaic panels]

How effective is Schottky photovoltaic conversion compared to silicon solar cells?

Compared with the commercially available silicon solar cells, the hot-carrier photovoltaic conversion Schottky device produced by our laboratory shows effective optical- to electrical-conversion ability for a wavelength above 1.1 microns, which is helpful to the utilization of the whole solar spectrum.

How efficient are silicon solar cells?

Using only 3–20 μm -thick silicon, resulting in low bulk-recombination loss, our silicon solar cells are projected to achieve up to 31% conversion efficiency, using realistic values of surface recombination, Auger recombination and overall carrier lifetime.

What factors affect the power conversion efficiency of silicon solar cells?

The power-conversion efficiency of silicon solar cells depends mainly on their electrical and optical properties, including the quality of silicon wafers (e.g. intrinsic purity and thickness), metal electrodes, surface passivation and light-harvesting capabilities of surface structures.

Can silicon solar cells absorb solar energy below Si bandgap?

Traditional silicon solar cells can only absorb the solar spectrum at wavelengths below 1.1 μm. Here we proposed a breakthrough in harvesting solar energy below Si bandgap through conversion of hot carriers generated in the metal into a current using an energy barrier at the metal–semiconductor junction.

What is a single reagent approach for silicon recovery from PV cells?

Single reagent approach for silicon recovery from PV cells A polycrystalline PV cell (Fig. 1 A) is primarily composed of high purity silicon and has silver busbars running on both front and back surfaces. The apparent blue colour of the front surface is due to the presence of the ARC, which is typically made up of silicon nitride (SiN x).

Can a self-made hot-carrier photovoltaic conversion Schottky device be compared with silicon p?

The self-made hot-carrier photovoltaic conversion Schottky device was compared with the commercially available silicon p–n junction solar cells. If the Si filter is not used, the efficiency of the silicon p–n junction cell under illumination is 17.67%.
