Abstract

Research has been conducted on Green Synthesis of copper nanoparticles using gambir leaf extract (Uncaria gambir Roxb) for Dye Sensitized Solar Cell. This study aims to determine the effect of the comparison of molar ratio variations (Cu(NO₃)₂) with gambir leaf extract through green synthesis of copper nanoparticles and I-V test of DSSC produced from copper nanoparticles through green synthesis. Sample preparation was carried out using the green synthesis method with the ratio of gambier leaf extract to (Cu(NO₃)₂) in sample variations of 1:1, 1:2, 1:3, 1:4 and 1:5. Copper nanoparticles were characterized using UV-Vis spectroscopy to determine the absorbance value and energy band gap and DSSC measured using a simple I-V test. UV-Vis spectrophotometer results on copper nanoparticles showed absorbance peaks in the 377 nm - 396 nm wavelength range, and obtained energy band gap values ranging from 2.84-2.91 eV. The resulting copper nanoparticles are round to elongated, due to the phenomenon of aggregation between particles. The efficiency obtained from DDSC is 4.26% and the FF value is 0.56.

Abstract

Copper nanoparticle (CuNP)-based thin films have great potential in various technological applications, such as electronics, catalysts, and sensors, due to their high conductivity value and enhanced surface reactivity. This study aims to fabricate CuNP-based thin films using the spraying method, which is known to be efficient for material deposition on substrates. In the spraying process, copper nanoparticles are sprayed on a transparent glass substrate and dried at room temperature to form a homogeneous thin layer. Characterization of the thin films using UV-Vis spectrophotometer to determine the energy band gap and transmittance value. The results of testing the energy band gap of copper nanoparticles with a ratio of 1, 2, 3, 4, and 5 amounted to 3.03 eV, 3.09 eV, 3.11 eV, 3.17 eV and 3.25 eV. Meanwhile, the transmittance test results show that the percentage of thin layer transmittance ranges from 20% to 90% with good crystal quality and a smaller energy band gap that has high electrical conductivity so that the thin layer produced has a decent quality to be applied to printed electronic devices.
