The efficient utilization of solar energy is important issue to shift to a sustainable society. In this study, the solar energy harvesting by utilizing stacked thermoelectric generators (TEG) with phase change material has been investigated. A one-dimensional thermoelectric model has been proposed by considering the heat balance including heat conduction, convective and radiation heat transfer, Perltier heat, Joule heat assuming constant solar radiation. The analytical results of electric power generation were almost agreeing with the experimental results. The optimum number of TEG to obtain maximum electric power was clarified analytically. The effects of concentration ratio of solar radiation were also discussed.
