摘要： In recent years, energy harvesting through photovoltaic has emerged as promising and long-term technology for energy production. However, for commercial applications, the fabrication of a photovoltaic solar cell requires an easy and low-cost process compatible with large-area and high-throughput production. In this work, we demonstrate a simple and fast light sintering technique for Cu2ZnSnS4 (CZTS) nanocrystal-based film. The CZTS nanocrystal-based film was irradiated with various intensity of light to observe the sintering effect. The significant sintering of CZTS film was achieved by irradiating with light intensity of 2.23 J/cm2 for 200 microseconds. The solar cell fabricated with light sintered CZTS nanocrystal-based film exhibited efficiency of 1.9% with open circuit voltage of 0.50 V and short-circuit current density of 11.5 mA/cm2 with fill-factor of 0.33. The light sintering technique can be further optimized for large-area sintering of nanostructures for various applications.
