Finite time thermodynamic optimizations based on the maximum power density has been performed for a solar-driven heat engine with internal irreversibility. In the analysis, it is assumed that the heat transfer from the hot reservoir is to be in the radiation mode and the heat transfer to the cold reservoir is to be in the convection mode. The power density function has been derived, and maximization of this function has been performed for various design parameters & their effects on optimum power densities have been investigated. The performance in the nominal power density output at operating conditions other than optimum working fluid temperatures has been studied with respect to the obtained efficiency.
