Crystalline　silicon　heterojunction　with　intrinsic　thin-layer　photovoltaic　(HIT-PV)　module　produces　more　output　power,　compared　with　the　c-Si　photovoltaic　module.　However,　it　presents　a　risk　of　overheating　in　hot　weather.　In　this　paper,　we　used　a　new　cooling　design　of　the　heterojunction　with　intrinsic　thin-layer　photovoltaic　thermal　(HIT-PVT)　module　to　lower　the　temperature　using　laminated　encapsulation　of　an　aluminum　collector　in　outdoor　climates.　The　measured　electrical,　thermal　and　total　efficiencies　of　a　HIT-PVT　system　can　catch　up　to　17.47%,　34.71%　and　52.18%,　respectively.　Moreover,　comparing　with　HIT-PV　module,　the　output　power　of　the　HIT-PVT　module　was　enhanced　by　5.58%　with　coolant　circulation,　and　the　converted　electrical　energy　can　be　increased　by　9.81%　with　the　designed　HIT-PVT　module.　In　addition,　the　primary　energy　savings　of　the　new　HIT-PVT　and　HIT-PV　systems　were　79.77%　and　43.71%,　respectively.
