This study investigates the enhancement of solar cell efficiency using nanofluid cooling systems, focusing on citrate-stabilized and PVP-stabilized silver nanoparticles. Traditional silicon-based perovskite cells were examined to assess impact these nanofluids improvement thermal management. A Central Composite Design (CCD) was employed vary nanoparticle concentration (0.2–0.8 wt%), coolant flow rate (0.5–1.5 L/min), irradiance (800–1000 W/m²). Efficiency improvements measured Ordinary Least Squares (OLS) regression. The experimental setup integrated systems with cells, facilitating efficient heat dissipation. Results showed significant gains: improved from 15 17% PVP stabilization, increased 18 21.1%. exhibited superior conductivity (0.7 W/m K) lower resistance (0.008 K/W) compared nanofluids, leading notable reductions in operating temperatures. For silicon temperatures dropped 50 °C 40 PVP, for 55 °C. Response Surface Methodology (RSM) identified optimal conditions maximum at 0.8 wt% 1.5 L/min rate. These findings underscore potential enhancing performance longevity. Future research should refine design, increase sample size, explore other types stabilization methods optimize contributes broader goal promoting widespread adoption energy as a sustainable alternative conventional sources.
