Abstract

A combined theoretical and experimental approach is developed for determining the local efficiency of multicrystalline silicon solar cells by use of quantitative lock-in carrierographic (LIC, also described as frequency-domain photoluminescence, LIP) and lock-in thermographic (LIT) imaging. The characteristic distribution of the saturation current density J₀, open-circuit voltage V_OC, fill factor FF, and efficiency of solar cell ηs are obtained, and the local inhomogeneities of a solar cell are readily determined by LIT and LIC imaging. The combination of a quantitative LIT and LIC imaging approach is a valuable tool for judging which local defects are especially harmful for degrading the fill factor or the open-circuit voltage.
