Abstract
In this contemporary study, theoritical investigation of nanofluidic model is thought-out. Two-dimensional nanomaterials based mixed flow is considered here. Convective solar radiative heat transport properties have been investigated over a nonlinearly stretched wall in the presence of magneto-hydrodynamic (MHD), by innovative application of semi analytical “optimal homotopy asymptotic method (OHAM)”. OHAM does not require any discretization, linearization and small parameter assumption. OHAM describes extremely precise order solutions without the need of computing further higher order terms, therefore, fast convergence is observed. Nanofluidic governing model is transformed into system of ordinary differential equations (ODEs) by exploitation of similarity transformation. To study the significance of radiation parameter along with thermophoresis parameter, a semi analytical solver is applied to the transformed system. In this work, Brownian motion , influence of magnetic field, Lewis number, Prandtl number, Eckert number and Biot number have investigated on velocity, temperature and nanoparticle concentration profiles. The study provides sufficient number of graphical representations to demonstrate the inspiration of mentioned parameters.

Summary
The most abundance renewable energy source for best alternative to conventional fossil fuelbased generation is solar energy. Electric energy and heat energy can be generated through sun light using photoelectric effect on photovoltaic panels and photothermal conversion on concentrated solar thermal plants, respectively. The increasing rate of solar absorption helps in improving energy output production of both photovoltaic panels and concentrated solar thermal plants. The efficient absorption of solar energy results in reliable use of renewable energy and better conversion into thermal energy, which results in least dependence on fossil fuels. CMES, 2022, vol.130, no.2 signification energy loss and low efficiency In this regard, water dispersed nanoparticles are being extensively studied for improving sunlight absorption. Nanomaterials are needed to widen this energy bandgap for absorbing more sunlight In this regard, a hybrid solar cell was proposed for more solar energy absorption from visible to near-infrared energy band
