Question

Defects in crystals improve efficiency of solar cells ?

Answer 1

Hi,

The answer of this question is,

YES! The defects in the crystal improves the efficiency of the solar cells.

Impurities are inserted deep into the crystals which creates holes into the solar cells. They provide a multi-step absorption mechanism for sub-band gap photons to create new electron-hole pairs which in return improve their efficiency.

I hope the answer satisfies you.

Thanks for asking.

Answer 2

It has been scientifically proved that defects in the crystals of solar cells improve the performance of a solar cell.

According to a recent research that done by the national renewable Energy Laboratory, certain defects that with energy level with proper engineering can improve the efficiency of solar cells. It can be stated as a form of improvement in the surface passivation of solar cells in its absorber layer.
