Further, connection terminals 504 are respectively arranged at both ends of the photovoltaic cable 503, and adjacent two photovoltaic cables 503 are electrically connected through the connection terminals 504.

[0037] The light-receiving surfaces of multiple photovoltaic panels 501 can be located in the same plane; or the light-receiving surfaces of multiple photovoltaic panels 501 may not all be located in the same plane, that is, the light-receiving surfaces of multiple photovoltaic modules can be staggered, so that the positions of multiple photovoltaic modules can be adjusted according to the concave and convex conditions of the building wall. In addition, adjacent two photovoltaic modules can be connected through the connection terminals 504. Assembling the photovoltaic curtain wall system on the building wall, the exhaust holes in the columns and crossbeams can accelerate the volatilization of the heat generated by the photovoltaic modules, achieving the purpose of cooling, thereby avoiding local thermal stress concentration on the photovoltaic modules, generating hot spots, ensuring the normal power generation of the photovoltaic modules, and preventing faults and potential safety hazards.

Specifically, one side surface of the auxiliary frame strip 102 is mounted on the column frame 101 through fasteners such as bolts, and the other opposite side surface is adhesively bonded to the photovoltaic panel 501 through glue such as structural adhesive, achieving the effect of the auxiliary frame strip 102.

[0047] By adopting columns or crossbeams with an internal hollow cavity structure, providing a through-hole structure suitable for allowing electronic devices to pass through on the side wall of the column or crossbeam, and covering the notch structure with a cover plate suitable for detachably connecting to the wire groove of the column or crossbeam, it is convenient to put the fixed photovoltaic cable 503 into the groove structure or remove it from the groove structure, which can prevent the electronic devices from being exposed outside, reduce the invasion of rain, sand and dust, make the photovoltaic cable 503 operate more stably and be more durable. When the electronic devices need to be maintained, only the cover plate needs to be disassembled, and the photovoltaic cable 503 can be maintained or disassembled and assembled from the opening structure. Thus, the maintainability of the photovoltaic modules of the photovoltaic curtain wall is better.
