Abstract
A window-integrated PV system was proposed that combines the exterior window of a building with PV panels, and its technical and economic performance was analyzed. A residential building in Seoul, South Korea, was used as a reference model, and third-generation PV panels (i.e., dye-sensitized solar cell (DSSC), and organic photovoltaic (OPV) with transparency characteristics) were analyzed. Regarding the technical performance of the PV panels, the window-integrated OPV system installed in household type B generated the most annual electricity (923.34 kWh), and the window-integrated DSSC system installed in household type A generated the least annual electricity (468.70 kWh). However, the window-integrated OPV system installed in household type C generated the most annual electricity per unit area (36.64 kWh/m2) and the DSSC system installed in household type B generated the least annual electricity per unit area (28.78 kWh/m2). In terms of economic performance, the NPV20 and SIR20 increased as the household’s monthly electricity consumption increased and the closer to the south the orientation of the PV panel was. These results show that the window-integrated PV system that used the third-generation PV panel is economically feasible and is expected to be one of the active strategies for achieving net-zero-energy buildings.
