Partitioned optimal design of semi-transparent PV curtain wall

The PV curtain wall usually consists of a sheet of laminated glass embedded with solar cells, a cavity filled with air or argon, and a piece of glass substrate [8].Traditional PV curtain wall with standard square-shaped solar cells usually results in a poor visual effect due to the obvious contrast between the opaque silicon solar cells and the transparent glass [9].

Performance study of ventilated energy-productive wall:

Yao et al. [22] simulated a PV curtain wall system with different design parameters under natural ventilation and found that the optimal air channel depth is 200 mm and the optimal height of the vents is about 200–300 mm. A more considerable gap depth would result in more backflow at the top. The change in density of air satisfies the
