摘要：

Nanostructured Cu2ZnSnS4 (CZTS) Kesterite thin film has been synthesized by inexpensive chemical bath deposition method in one step on glass substrate. Structural, optical and electrical properties of as grown Kesterite CZTS thin film have been investigated. The Kesterite structure of the CZTS thin film has been confirmed by XRD. Whereas polycrystalline nature of the film has been confirmed from the concentric ring pattern obtained from TEM-SAED. Kesterite CZTS film shows higher absorption in visible region with band gap Eg = 1.68 eV. The obtained band gap is in the range of optimum value of solar spectrum for solar radiation, results in higher absorption of light. I-V measurement in dark and under illumination of light (200 W/cm(2)) reveals high photocurrent in dark as well as in light. The calculated photosensitivity and photoresponsivity were 52 % and 16.9 mu A/W respectively.
