The errors of EQE(λ) SC was deduced for the areas of test sample being larger than areas of illumination. However, the errors can be minimized using open-circuit voltage to measure EQE(λ) OC of solar cells. And the expressions of EQE(λ) OC were explored using J-V characteristics and open-circuit voltage of solar cells. The EQE(λ) SC can be expressed by EQE(λ) OC and f EQE. At last, curves of EQE(λ) OC and EQE(λ) SC of different crystalline silicon solar cells were measured, and then they were compared with EQE(λ) SCPC1D simulated by PC1D. The method can minimize the errors of the EQE(λ) measurements of solar cells.
