Summary: This study investigates the impact of particle size and concentration of TiO2 nanoparticles in black paint on the solar still absorber surface temperature. The introduction of TiO2 nanoparticles increases the surface temperature, with larger particle sizes contributing to higher temperatures. The increase in temperature is attributed to high UV absorption and improved light-scattering ability with larger particle sizes.
