Fair glass and building integrated photovoltaic module including fair glass

摘要

PURPOSE: Multiple glass and a solar cell module integrated with a building including the same are provided to prevent the destruction of the multiple glass by maintaining both air layers under a constant pressure if the pneumatic pressures of the air layers are different. CONSTITUTION: Multiple glass includes an outer glass(G2), an inner glass(G1), a middle glass(G3), and a spacer(10). The spacer hermetically bonds the outer glass, the inner glass, and the middle glass. A through path is formed. An air layer(A2) is formed between the outer glass and the middle glass. Another air layer(A1) is formed between the inner glass and the middle glass. If the pneumatic pressures of the air layers are different, air from the air layer under a relatively high pressure is moved to an air layer under a relatively low pressure through the through path.
