KR101638419B1: The present invention relates to a building-integrated photovoltaic module and a ventilation curtain wall including the same. A ventilation space is formed between the rear side of a BIPV module and an insulation member, and the left-right frame of the BIPV module and the left-right frame of the curtain wall are combined air-tightly. The up-down frame of the BIPV module and the up-down frame of the curtain wall are not combined but separate from each other, so a ventilation part of forward convection current linked with the ventilation space is formed. As a result, the ventilation efficiency by the forward convection current ventilation can be improved, the insulation performance of the photovoltaic module can be secured, performance deterioration due to overheat of the photovoltaic module can be prevented, and the BIPV module can be attached or detached easily through the ventilation part. By doing so, the present invention can reduce time and costs necessary for installation or maintenance of the BIPV module
