Question

Improvement of the conversion efficiency of polycrystalline silicon thin film solar cell

Answer 1

Conversion efficiency of polyvrystalline silicon thin film solar cell.

Answer 2

Answer:

The main benefit of the solar cell device is a reduction in the open-circuit voltage (Voc) deficit, which is significantly reduced by changing the absorber formation.

Explanation:

• The improved photoluminescence performance suggests that this is related to lower fault density.
• As a result of this improvement in absorber quality, the effects of a wider absorber bandgap might be reaped.
• The reverse saturation current density and Voc both improved dramatically.
• Meanwhile, a heavier alkali treatment utilising caesium on the absorber surface was used to improve the device's performance.
• As a result of the huge improvements in Voc and fill factor, this record-breaking efficiency was achieved.
• These findings have been rigorously replicated and will be used to improve Solar Frontier's module performance shortly.

Hence, "A solar cell can only generate as much electricity as the wavelength range it can absorb." If the band range is improved then both voltage and efficiency by stacking cells is increased."
