This systematic review outlines the application of thermoelectric generators (TEGs) as energy sources in CubeSats. While CubeSats currently rely on solar cells with efficiencies between 16.8% and 32.2%, their performance diminishes increased distance from Sun. TEGs, although used radioisotope (RTGs) for satellites, remain underutilized A literature revealed 33 relevant articles, 21.2% employing simulation software to evaluate thermal behavior. Among 34 patents, only one mentioned micro-TEGs, most focusing structural improvements. Patent activity peaked 2016 2020, emphasizing optimization, but no patents addressed TEGs CubeSats, highlighting a significant research gap. present viable solution harnessing residual heat
