Nanoparticles have the potential to enhance the performance of solar PV thermal hybrid systems through various mechanisms. Here are several ways in which nano-particles can be utilized to improve the functioning of such systems. In this study, a three dimensional transport of incompressible nano-fluids for bifacial solar photovoltaic-thermal energy system has been investigated for a non-linearly stretched elastic sheet. A mathematical model of passive control of nano-particle volume fraction is considered. The similarity transformations are used for having selfsimilar forms of boundary layer equations. Optimal Homotopy Asymptotic method (OHAM)is selected for obtaining the numerical solutions. The results have been presented for parametric analysis of three dimensional nanofluid transport over stretched sheet against variations in different physical parameters. In this work, impacts of stretching ratio, Brownian motion parameter, Lewis number, thermophoresis parameter and Schmidt number are investigated for velocity, nano-particle volume, and temperature profiles.It is deduced that power-law index has a declining trend against nano-particle volume fraction and penetration depth of temperature. It is also observed that the heat transfer rate and temperature are insignificantly affected by Brownian motion of nano-particles.
