Recently, the domestic BIPV market is expected to revitalize with the introduction of the "zero-energy building certification system(2020~)", but it is somewhat stagnant due to the rigidity of definitions in the current domestic BIPV construction standards. Also, since there is delaying revision on definition and standardization of BIPV, the system is so weak that there are cases where it has been approved as BIPV simply by installing a structure on the wall and fixing the module roughly. The damage caused by this can be passed on to consumers, and it can only create a negative perception of BIPV and jeopardize the entire market. The BIPV definition was prepared through a Delphi survey of related experts about market stagnant cause, unreasonable regulation, etc, and a revised plan was derived accordingly.

Building Integrated Photovoltaic (BIPV) is one of the best ways to generate electric power using the solar energy, which is clean and inexhaustible energy resources. The most of BIPV modules have the form of GtoG (Glass to Glass) photovoltaic in building applications. Degradation leading to failure in photovoltaic modules is very important factor in BIPV modules. This paper analyzed the performance of various BIPV modules through outdoor exposure tests. Performance of three BIPV modules(c-Si type, a-Si type and DSSC type) with three installation angles influenced by sun light, outdoor temperature, and wind velocity was monitored and analyzed. As a result, c-Si type BIPV module outperforms other BIPV modules(a-Si type). In terms of power efficiency of the module, the installed angle of $45^{\circ}$ is better than others(90 degree, 0 degree). In addition, more realistic data of various BIPV system performance could be available through the field test and integrated building test. In this study, relationship of the BIPV system is identified module's installation angle, power generation, architectural performance, etc.

The BIPV system must be designed to reflect the architectural and electrical characteristics simultaneously because it replaces the role of the exterior material of the building, which makes it difficult to design the BIPV. The thin film type BIPV module has an electrical characteristic that the open voltage is higher and the short circuit current is lower than that of the crystalline type BIPV module. However, there are many differences in the design of the array, the collector distribution board, and the inverter in the system configuration since the crystal type BIPV module has the opposite feature. In this study, a crystalline BIPV module and a thinfilm BIPV module were applied to actual buildings. As a result, the elements to be considered in designing BIPV system were derived, and the architectural and electrical characteristics were mutually analyzed.

The various colors and transparency of DSC and operability unrelated with directions greatly expand the use of BIPV, as a multi-functional composite of module. Therefore the possibility of DSC BIPV is examined by the case study and the analysis and then its applicability is examined. Most of the DSC BIPVs, which are found through a total of six case studies and analyzes in Korea and abroad, are mainly implemented with window glass and shading devices. This is related to the DSC transparency property. Improvements are due to the irritation of the eye due to the color of the red module. Therefore, it is important to take into account the color of the BIPV window depending on the use of the building and the room. Meanwhile, some colors of application model may stimulate eyes and such colors should be considered by use of buildings and rooms in the application of BIPV window. DSC BIPV has prospective diffusibility with the development of flexible module for the application of building surface.

This study has been carried out empirical research on Transparent Thin-film BIPV modules, BIPV modules installed on the exterior of the building are applied a laminated module 1kWp, double-glazing module 3kWp and triple-glazing module 1kWp. Applied to the total capacity of BIPV modules are 5kWp. In this study, design and construction process of BIPV systems is presented. In addition, through monitoring of the BIPV system, the temperature and the power characteristics of each module were analyzed. During the measurement period, the module temperature measurement results, the maximum surface temperature of $51.5^{\circ}C$ triple-glazing BIPV module showed the highest, followed by double-glazing BIPV module $49.1^{\circ}C$, $44.7^{\circ}C$ laminated modules, respectively. Power output results, the daily average double-layer modules showed 4.10kWh/day, triple-glazing module 1.57kWh, respectively 1.81kWh laminated modules. In particular, the power efficiency of triple-glazing BIPV module was lower than the power efficiency of the laminated BIPV module. This phenomenon is considered to be affected by the module temperature. In the future, BIPV modules in this study the relationship between module temperature and power characteristics plans to identify.

BIPV시스템 분야는 다른 PV 적용 기술 분야에 비해 빠르게 성장하고 있으나 소형 건축물 위주로 적용되었으며, 초고층 건축물과 같이 수직적으로 높은 건축물의 외부환경조건에 대응하기 위한 BIPV의 적용 방안은 현재까지 연구되어지지 않았다. 국내의 경우 선진국에 비해 초고층 건축물에 대한 BIPV시스템 적용기술은 아직 초기 연구단계에 불과하다. 초고층 건축물의 고유의 특징을 고려하여 초고층 건축물 파사드에 입사하는 일사량의 분포가 균일하지 않을 것이라고 예측하고 실측을 진행하였으며, 실측 결과의 분석을 통하여 초고층 건축물에서의 BIPV시스템 최적 설계방안을 제시하였다. 결론적으로 본 연구에서는 초고층 건축물의 외벽에 입사하는 일사량을 고려한 Unit형 BIPV설계 방안을 제시하였으며, 특히, 측정된 일사량 데이터를 활용하여 초고층 건축물에 적합한 인버터의 선정의 대안을 제시하였다.

In order to increase the self-reliance rate of new and renewable energy in order to respond to the mandatory domestic zero-energy buildings, the taller the building, the more limited the site area, and installing PV modules on the roof is not enough. Therefore, BIPV (Building integrated photovoltaic, hereinafter BIPV) is the industry receiving the most attention as a core energy source that can realize zero-energy buildings. Therefore, this study conducted a survey on the problems of the BIPV industry in a self-discussing method for experts with more than 10 years of experience of designers, builders, product manufacturers, and maintainers in order to suggest the right direction and revitalize the BIPV industry. Industrial problems of BIPV adjustment are drawn extention range of standard and certification for products, range improvement for current small condition of various kind productions, need to revise standards for capable of accomodating roof-type, color-module and louver-module, necessary of barrier in flow of foreign modules into korea through domestic certification mandatory, difficulty in obtaining BIPV information, request to prevent confusion among participants by exact guidelime about architectural application part of BIPV, and lack of the BIPV definition clearness, support policy, etc. Based on the improvements needed for the elements, giving change and competitiveness impacts aims to present and propose counter measures and direction.

To assess the performance and characteristics of colored building-integrated photovoltaic (BIPV) modules, a comparative assessment of empirical performance was conducted on colored BIPV modules (gray, blue, and orange) and general BIPV module. These modules were installed on the south-facing slope (30°) for comparative assessment through a field test. Monitoring data were collected every 10 min from December 20, 2019 to January 21, 2020 and used to performance and characteristics analysis. Performance ratio and module efficiency were utilized during performance indexing for comparative assessment. For general BIPV modules, the operational efficiency was analyzed at 16.63%, whereas for colored BIPV modules, 13.70% (gray), 15.12 % (blue), and 14.49% (orange) were analyzed. It was discovered that the efficiency reduction caused by transmission losses owing to the application of colored cover glasses were 17.74% (gray), 9.05% (blue), and 9.86 % (orange), under field testing conditions. These values turned on an additional 7% reduction in efficiency for gray BIPV modules, compared to the degradation resulting from transmission drop (gray: 10.87%, blue: 8.99%, and orange: 9.02%) calculated using the efficiency of each module in standard test conditions (STC). Performance ratio analysis resulted in the following values: 0.92 for general BIPV modules, and 0.85 (gray), 0.91 (blue), and 0.91 (orange) for colored BIPV modules. As demonstrated by the above results, modules with a colored cover glass may differ in their operational performance depending on their color, unlike general modules. Therefore, in addition to the performance evaluation under STC, additional factors of degradation require consideration through field test.
