In this study, three different types of experimental models of BIPV curtain wall units with GIGS modules were built, and their thermal and electrical performances were analyzed. The experimental results showed that the temperature of the rear side of the GIGS module with the application of an insulation in the curtain wall spandrels was higher than a GIGS module standalone by $22^{\circ}C$, 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 $142^{\circ}C$ 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 GIGS module with insulation layer reduced the electrical performance of the module. Based on this, it is claimed that providing sufficient ventilation at the GIGS applied spandrels contribute to improve the power generation of the GIGS module.

It is more necessary to consider the various factors for developmenting visible PV module of alternative window than traditional PV module. It must have sufficient performance which is Tvis, daylighting, daylight factor, glare index. so that more needs to consider suitable plan and total evaluated technology. Under the this background. For using commonly a combination BIPV module system and Daylinghting that can alternative architectural window, our goal on this study is drawing proper window area ratio as the window by analyzing lighting performance and glare index depending on transmittance of DSSC. On this study, we drew the result about window area ratio that can apply in the building when applying DSSC in the window. In situation that window is alternated as curtain wall in atrium that has big Widow area, if applying red 15.8% DSSC of low transmittance, it is expect to proper because it is suitable illumination standard and doesn't occur a discomfort glare. In case of office, we propose to apply red 33.2% or blue 35.2% DSSC of high transmittance for no affecting lighting load. we expect to contribute to select proper and effective window when applying the window in the building by drawing the window area ratio that can apply in thee building depending on transmittance of DSSC and offering the glare index data.

LCPV modules under 5 suns consist of reflective optics and receiver modules, similar to a typical fixed concentration PV module. If they are to be used as a compound parabolic concentrator, which is filled with a dielectric material, a compact plate structure of the fixed CPV can be designed and built at a large acceptance angle. These types of flat-$plate{\mu}$-LCPV modules are suitable for building integrated photovoltaic modules, facade applications, mobile devices, and small home appliances. Therefore, in this study, the possibilities for other application devices were studied and presented by designing and fabricating LCPCs for CPV modules.

Building-integrated photovoltaic(BIPV) perform traditional architectural function of walls and roof while also generating electricity. But most of the absorbed solar energy appears passively as heat, raising the temperature of cells and reducing the efficiency with which the active part is converted into electricity. Therefore this paper presents the comparison of electrical, architectural and thermal performance of roof integrated photovoltaic(PV) modules, which is composed of different hybrid structure layer such as urethane form, waffle stud etc.

In this study, we fabricated light-weight solar module for various applications such as building integrated photovoltaics (BIPV), vehicles, trains, etc. Ethylene tetra fluoro ethylene (ETFE) film was applied as a material to replace the cover glass, which occupies more than 65% of the weight of the PV module. Glass fiber reinforced plastic (GRP) was applied to the ones with a low durability by replacing the cover glass to ETFE. Moreover, to achieve a high solar power conversion in this study, we applied a shingled design to weight reduced solar modules. The shingled module with GRP shows 183.7 W of solar-to-power conversion, and the output reduction rate after weight load test was 1.14%.

Dye-sensitized solar cell (DSC) allows light transmission and the application of various colors that make it especially suitable for building-integrated PV (BIPV) application. In order to apply DSC module into windows, it has to be panelized: DSC module should be protected with reinforced glass to the entire surface. Up to date, it seems to be common to make double glazing with DSC modules with air gaps between the glasses and the DSC modules. Few research has been conducted on the characteristics of various glazing types with DSC modules. This study aims to analyze the electrical performance of DSC modules according to panelizing method for glazing unit with DSC modules. The prototype of the DSC glazing that applied silicone filler between DSC modules and glasses was developed. The electrical performances of this type of DSC glazing with the filler and rather conventional double glazing with DSC modules were compared. Their performances were measured using a solar simulator that is suitable for DSC performance testing. The results indicated that the electrical performance of the filler type DSC glazing improved by 7% compared to that of the conventional DSC double glazing type.
