The quantum efficiency (\(Q_e\)) of a solar cell is the ratio of charge carrier produced at the external circuit of the cell (electronic device) to the number of photons received (or absorbed) by the cell. There are two ways this quantum efficiency ratio is calculated: (i) external quantum efficiency and (ii) internal quantum.

Hydrogenated amorphous silicon (a-Si:H) thin-film solar cells with n-i-p structure are simulated using AFORS-HET (Automated For Simulation of Heterostructure) software and fabricated using radio-frequency plasma-enhanced chemical vapor deposition (RF-PECVD) (13.56 MHz) multi-chamber system at a low temperature of 180 °C.
Thin-film technology has made it possible to produce low-cost solar cells. This is mainly due to plasma-assisted chemical vapor deposition technology that enables the production of thin-film solar cells by growing silicon (Si) layers instead of stacking silicon wafers.
