A comprehensive evaluation of solar cell technologies,

Moreover, the efficiency of a solar cell is the ratio of electrical output at maximum power point (MPP) and total power of incident light. The electrical output at the maximum power point can be obtained by multiplying the current (J mp) and the voltage (V mp) of the cell at MPP. Therefore, the efficiency ɳ can be expressed as Equation (3

2.1 Quantum efficiency of solar cells. 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 efficiency.
