EFFECT OF SERIES AND SHUNT RESISTANCE ON THE PERFORMANCE OF KESTERITE SOLAR CELLS

Abstract

Kesterite devices are created from cheap, readily available, non-toxic basic components. Due to their p-type conductivity, direct band-gap shifts, comparatively high absorption coefficient, and adjustable band-gap, kesterite semiconductors have attracted a lot of attention from scientists for use in solar cells.The efficiency and overall performance of kesterite solar cells are influenced by various factors, including the incorporation of series and shunt resistances. In the present communication, we report the effect of series and shunt resistance on the photovoltaic performance of CZTSe kesterite solar cells. The relationship between series resistance and device parameters, such as fill factor, the open-circuit voltage, the short-circuit current density and the efficiency, is explored, providing valuable insights into device optimization. The efficiency was found to decrease with increase in the series resistance and vice-versa.
