<p>Concentrated photovoltaic (CPV) technology aims to optimize solar energy conversion efficiency. The portion of light in a solar cell that does not convert to electricity turns into thermal heat. The waste heat induces thermal strains and raises the temperature of the solar cells. The operating temperature of the cell influences efficiency, power output, and longevity. The MJT cell is a high-efficiency solar cell. It is regarded as the most efficient photovoltaic cell documented globally to date. The power output and efficiency of the MJT cell are contingent upon the operating temperature. The efficiency of the solar cell diminishes as the operating temperature rises. Enhanced power, voltage, efficiency, and longevity can be attained through effective cooling and operation of the MJT under conventional cell testing settings. Conventional active cooling techniques can complicate systems and increase energy usage, underscoring the necessity for sustainable alternatives. Passive cooling systems present a viable answer by utilizing natural processes to expel heat without necessitating supplementary energy consumption. This paper aims to examine how various passive cooling methods can enhance the performance of CPV systems. These methods include extended surfaces, heat pipes, micro fins, microfibers, nanofluids, radiative cooling, pulsed currents, and phase change materials. The ideas, applications, and effectiveness of each strategy are thoroughly examined to yield insights for enhancing CPV thermal management. This research study will help in the exploration of an appropriate cooling system so that the suggested MJT CPV system can reach optimal efficiency. The paper examines novel strategies to enhance the production of concentrated photovoltaics (CPV).</p>
