Nanotechnology Applications in Photovoltaic Cell Efficiency Enhancement

Abstract

The low efficiency of traditional PV cells does not make solar power utilize well; thus poor efficiency results. Nanotechnology is offering new avenues to improve absorption of light and charge transfer. Investigate the effects of nanomaterials in any way on the efficiency of the PV cell by controlled experimental setup. A quasi-experimental quantitative design was adopted. Thirty PV cell samples were tested—15 traditional (control) and 15 nanotech-enhanced (experimental). Nanomaterials used included quantum dots, carbon nanotubes, and metallic nanoparticles. Nanotech-enhanced cells showed a mean efficiency gain of approximately 6.3%. Statistical analysis (t-test and regression) confirmed the significant positive impact of nanomaterials on PV performance. The findings validate the hypothesis that nanotechnology improves solar efficiency and align with existing literature. The study contributes empirical evidence to the growing field of nanotech-based renewable energy solutions. Future research should explore hybrid nanomaterials and conduct real-world field testing under diverse environmental conditions.
