The application of photovoltaics into building as integrated building components has been paid more attention worldwide. Photovoltaics or solar electric modules are solid state devices, directly converting solar radiation into electricity; the process does not require fuel and any moving parts, and produce no pollutants. And the prefab building method is very effective because the pre- manufactured building components is simply assembled to making up buildings in the construction fields especially the sandwich panel. So, the purpose of this research is to integrated prefab building materials depending on the cooling type of PV modules. It is concluded that the prediction of BIPV system's performance should be based on the more accurate PV module temperature. From the basis of these results on the correlation of temperature and irradiation were obtained.

The types of installation of the photovoltaic system applied to domestic residential buildings are classified as follows: Mounted modules with air circulation, semi-integrated modules with air duct behind, integrated modules with fully insulated back. In order to study generation characteristics of PV system, we verified the validity of interpretation program based on long-term measurement data of demonstration house installed in BAPV form and also analyzed the generation characteristics and performance of each installation type. The results are as follows. First, the RMSE of amount of generation and simulation according to annual daily insolation of demonstration system located in Daejeon was 0.98kWh and the range of relative error of monthly power generation was -5.8 to 3.1. Second, the average annual PR of mounted modules was 82%, semi-integrated modules 76.1% and integrated modules 71.9%. This differences were attributed to temperature loss. Third, the range of operating temperature of annual hourly photovoltaic modules was -6.5 to $61.0^{\circ}C$ for mounted modules, $-6.0{\sim}73.9^{\circ}C$ for semi-integrated modules and -5.5 to $88.9^{\circ}C$ for integrated modules. The temperature loss of each installation type was -14.0 to 16.1%, -13.8 to 21.9%, and -13.6 to 28.5%, respectively.

본 연구에서는 건물 외벽 태양광 발전 통합 시스템(BIPV: Building Integrated Photovoltaic System)용 컬러 유리의 구조를 제안하고 이를 구현하기 위한 공정 기술을 개발하였다. 굴절률 값이 다른 두 종류의 산화 금속 박막을 집적함으로써 투과도가 우수하면서도 서로 다른 컬러를 구현할 수 있음을 파동광학에 기반한 전산모사를 통해서 확인하였다. 선택된 구조를 구현하기 위해 RF Magnetron 증착 방법을 통해 목표로 하는 두께를 균일하게 얻을 수 있는 공정을 개발하였다. 실험 시편에 대한 광학적 분석을 전산모사 결과와 비교하여 분석한 결과, 원하는 컬러 유리를 랩 스케일에서 안정적으로 구현할 수 있음을 알 수 있었으며, 상온에서 일주일 이상의 안정성을 갖는 것을 확인하였다. 이러한 기술은 BIPV 건축물을 구축하는 데에 유용할 것으로 기대된다.

BIPV(Building Integrated PV) system can expect dual effects that reduce expenses for establishment of PV system by adding new function as outer covering material of building expect producing the electricity. But, there are many generation differences according to the exterior environmental facts(solar cell array, design and installation condition of interactive inverter system) Therefore, it is difficult to optimum design. Consequently in advance design system, we experiment 3kW BIPV(Building Integrated PV) generation. We concrete PV system efficient application of variable. BIPV system that is proposed in this paper, was established in Solar Energy research center of Chosun University, composed with system. This research is a basic study for application of building integrated photovoltaic system for building

This paper is proposed cooling system of BIPV(Building Integrated Photovoltaic) by micro-controller. The output power of PV generation system is not systematically tracked and influenced by various factors; solar irradiance, solar cell temperature. The temperature of solar module should be minimized to increase electrical output. Therefore, it is proposed that micro-controller cools to decrease temperature of solar module using thermoelement. The validity of this paper is proved by comparing solar module temperature of cooling system and un-cooling system.

This paper presents a method for determining the optimum active-area width (OAW) of solar cells in a module architecture. The current density-voltage curve of a reference cell with a narrow active-area width is used to reproduce the current density profile in the test cell whose active area width is to be optimized. We obtained self-consistent current density and electric potential profiles from iterative calculations of both properties, considering the distributed resistance of the contact layers. Further, we determined the OAW that yields the maximum efficiency by calculating efficiency as a function of the active-area width. The proposed method can be applied to the design of the active area of a dye-sensitized solar cell in Z-type series connection modules for indoor and building-integrated photovoltaic systems. Our calculations predicted that OAW increases as the sheet resistances of the contact layers and the intensity of light decrease.
