In this study, three different types of experimental models of BIPV curtain wall units with CIGS modules were built, and their thermal and electrical performances were analyzed. The experimental results showed that the temperature of the rear side of the CIGS module with the application of an insulation in the curtain wall spandrels was higher than a CIGS module standalone by 22℃, which results in a reduction in the power generation of the former by 8 %. On the other hand, when ventilation was applied to the model to improve the power generation performance, the module temperature was observed to be 14.2 ℃ lower compared to the enclosed type, and the power generation performance improved by 5 %. It confirmed that the temperature increase in the rear side of the CIGS module with insulation layer reduced the electrical performance of the module. Based on this, it is claimed that providing sufficient ventilation at the CIGS applied spandrels contribute to improve the power generation of the CIGS module.
