Internal quantum efficiency (IQE): The ratio of number of charge carriers generated to the number of photons absorbed by the solar cell is called Internal Quantum Efficiency of solar cell. IQE helps in determining the ability of the solar cell in converting absorbed photons into charge carriers.
Generally, I–V curves are given preference when measuring the performance of solar cells and less emphasis is given to spectral response, internal quantum efficiency (IQE), and external quantum efficiency (EQE) quantum.
The IQE helps in determining the efficiency of solar cell. Thus, the use of reflectance data to determine the internal quantum efficiency of a solar cell involves equipment setup, dark current and voltage measurements, reflectance measurement, absorption coefficient calculation, and IQE.
The characterization of a solar cell typically involves measuring its current–voltage (IV) curve, external quantum efficiency (EQE), capacitance–voltage (CV) curve, and transient photovoltage (TPV) response.
Other than spectral response, there are many other factors, i.e., weathering, mishandling, aging, etc., that could contribute to the inefficiency of solar cells and this can be projected clearly by obtaining a solar cell’s quantum efficiency as well as its spectral response.
These techniques include measurements of the solar cell's current–voltage (IV) curve, external quantum efficiency (EQE), capacitance–voltage (CV) curve, and transient photovoltage (TPV) response. IV curves provide information on the solar cell's maximum power output, open-circuit voltage, short-circuit current, and fill factor.
