ABSTRACT = {Solar cells can transform light energy into electrical energy, possibly removing the need for 
fossil fuel energy resources. Reflection loss in solar cells is a factor contributing to 
diminished power conversion efficiency, which can be solved through using antireflective 
coatings on the cell surface. The present research primarily focuses on the development and 
application of antireflection coatings on the top surface of silicon solar cells. Sb<sub>2</sub>Se<sub>3</sub> was 
deposited over multi-crystalline Si cells with different durations from 15 to 60 minutes. The 
influence of thin film Sb<sub>2</sub>Se<sub>3</sub> coated cells was investigated through optical, current, voltage 
and thermal study. The ideal thickness of the Sb<sub>2</sub>Se<sub>3</sub> coating was determined to be 1.336 µm 
for SB3 sample using FESEM. The lowest optical reflectance of 5.8% and highest 
absorbance of 93.4% was reached after 45 minutes of coating (SB3) across the 300 to 1200 
nm wavelength band. The minimum electrical resistivity of a 45-minute coated Sb<sub>2</sub>Se<sub>3</sub> 
sample was determined as 5.09×10<sup>−3</sup>
Ω-cm. The improved power conversion efficiency of 
Sb<sub>2</sub>Se<sub>3</sub> coated solar cell under open sunlight setting was increased from 15.31 to 21.18% 
particularly for SB3 solar cell sample, which optimize maximum transfer of incident 
photons into the solar cell. From the observed results, it indicates that Sb<sub>2</sub>Se<sub>3</sub>  nanocoating 
has identified to be ideal antireflection coating material for polycrystalline silicon solar cells.},
