The　electrical　performance　evolution　of　a　system　combining　photovoltaic　(PV)　and　thermoelectric　generator　(1＇E)　is　evaluated　using　thermal　resistance　calculations.　The　hybrid　system　combines　a　commercial　monocrystalline　silicon　PV　and　a　commercial　bismuth　telluride　TE　that　is　integrated　with　heat　sinks.　Here,　photovoltaic　modules　could　be　cooled　using　thermoelectric　components,　leading　to　an　increase　in　its　output　power.　Additionally,　extra　thermal　electricity　is　generated　from　the　temperature　difference　between　the　backside　of　photovoltaic　modules　and　heat　sinks.　Compared　with　the　PV,　the　photovoltaic　conversion　efficiency　of　the　PV/TE　integrated　system　is　increased　by　3.9%　and　the　total　system　efficiency　is　up　to　5.9%.
