The　increase　of　operating　temperature　on　a　photovoltaic　(PV)　cell　degrades　its　electrical　efficiency.　This　paper　is　organized　to　describe　our　latest　design　of　an　aluminum　substrate-based　photovoltaic/thermal　(PV/T)　system.　The　electrical　efficiency　of　the　proposed　PV/T　can　be　increased　by　similar　to　20%　in　comparison　with　a　conventional　glass　substrate-based　PV.　The　work　will　benefit　hybrid　utilization　of　solar　energy　in　development　of　building　integrated　photovoltaic　systems.
