  • Two kind of Ag-pastes were prepared for integrating the bulk Si solar cell. One is the Ag-paste with Pb-based glass frit and the other is that with Bi-based glass frit. The pastes were the mixture of 84 wt% Ag, 2 wt% glass frit, 11 wt% solvent of buthyl cabitol acetate, and 2 wt% additives. After fabricating the Ag-pastes, they was coated on a $SiN_x$/n+/p- stacks of a commercial mono-Si solar cell. The solar cell efficiency was 17.6% in the case of the Pb-based Ag-paste. However that was 16.2% in the solar cell integrated with the Bi-based Ag-paste. The lower performance in Bi-based Ag-paste was caused by the higher series resistance and the lower shunt resistance in comparison with the Pb-based Ag-paste.

  • Currently, BIPV (Building Integrated Photovoltaic) design technology lacks analysis function at the planning stage, and there is a lack of understanding and reliability of BIPV design method and system for building designers. To design and consider various building integrated solar design alternatives, the color of building integrated solar is often monotonous or does not match the design direction of the building. In this study, architectural designers can select various color modules in the planning and design process of the building and analyze the characteristics of color module solar cells and compare and analyze the actual solar radiation and predicted solar radiation in Republic ofKorea Seoul to reduce the confusion of design methods. By building a BIM design integrated system that can prove the quality of the building and analyze the shading analysis and power generation performance architecturally, it can improve the reliability of color module solar cell applicability that can express aesthetics in buildings and the predicted solar power generation capacity of each region. In the initial design stage, based on the empirical data of the BIPV system, it is possible to analyze the power generation performance for each installation angle and installation direction by analyzing the surrounding environment and the installation area, and accurately determine the appropriateness of the design accordingly.

  • This paper proposes a new methodology on reliability evaluation of a power system including solar cell generators (SCG). The SCGs using renewable energy resource such as solar radiation(SR) should be modeled as multi-state operational model because the uncertainty of the resource supply may occur an effect as same as the forced outage of generator in viewpoint of adequacy reliability of system. While a two-state model is well suited for modeling conventional generators, a multi-state model is needed to model the SCGs due to the random variation of solar radiation. This makes the method of calculating reliability evaluation indices of the SCG different from the conventional generator. After identifying the typical pattern of the SR probability distribution function(pdf) from SR actual data, this paper describes modelling, methodology and details process for reliability evaluation of the solar cell generators integrated with power system. Two test results indicate the viability of the proposed method.

  • Photon conversion technology for thin film solar cells is reviewed. The high-energy photons which are hardly absorbed in solar cells can be transformed the low energy photon by the photon conversion process such as down conversion or down shift, which can improve the solar cell efficiency over the material limit. CdSe-based quantum dot materials commonly used in LED can be used as the photon conversion layer for Si thin film solar cells. The photon conversion structure of CdSe-based quantum dot for Si thin film solar cells will be presented and the pros and cons for the Si thin film solar cells integrated with the photon conversion layers will be discussed.

  • 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.

  • Luminescent solar concentrator (LSC), consisting of luminophore included glass or substrate with edge-mounted photovoltaic cell, is semi-transparent, energy harvesting devices. The luminophore absorbs incident solar light and re-emit photons, while the waveguide plate allows re-emitted photons to reach edge or bottom mounted photovoltaic cells with reduced losses. If the area of LSC is much larger than that of photovoltaic cell, this system can effectively concentrate solar light. In order to improve the performance of LSC, new materials and optical structures have been suggested by many research groups. For decreasing re-abosprion losses, it is essential to minimize the overlap between absorption and photoluminescence solar spectrum of luminophoroe. Moreover, the combination of selective top reflector and reflective optical cavity structure significantly boosts the waveguide efficiency in the LSC. As a result of many efforts, commercially available LSCs have been demonstrated and verified in the outdoor. Also, it is expected to generate electricity in buildings by replacing conventional glass to LSCs.

  • Recently, the installation of photovoltaic modules in urban areas has been increasing. In particular, the demand for solar modules installed in a limited space is increasing. However, since the crystalline silicon solar module's size is proportional to the solar cell's size, it is difficult to manufacture a module that can be installed in a limited area. In this study, we fabricated a solar module with a shingled design that can control horizontal and vertical width using a bi-directional laser scribing method. We fabricated a string cell with a width of 1/5 compared to the existing shingled design string cells using a bi-directional laser scribing method, and we fabricated a solar module by connecting three strings in parallel. Finally, we achieved a conversion power of 5.521 W at a 103 mm × 320 mm area.

  • Selenium (Se)-rich binary Cu-Se and In-Se nanoparticles (NPs) were synthesized by a modified heat-up method at low temperature ($110^{\circ}C$) using the gum exudates from a cherry blossom tree. Coating of CISe absorber layer was carried out using Se-rich binary Cu-Se and In-Se NPs ink without the use of any external binder. Our results indicated that the gum used in the synthesis played beneficial roles such as reducing and capping agent. In addition, the gum also served as a natural binder in the coating of CISe absorber layer. The CISe absorber layer was integrated into the solar cell, which showed a power conversion efficiency (PCE) of 0.37%. The possible reasons for low PCE of the present solar cells and the steps needed for further improvement of PCE were discussed. Although the obtained PCE is low, the present strategy opens a new path for the fabrication of eco-friendly CISe NPs solar cell by a relatively chief non-vacuum method.

  • This study is a study on the building integrated method of Photovoltaic. It was analyzed into a basic installation condition and an integrated form in this study. And it was confirmed through the 3D simulation & drawing work of an integrated situation to the real domestic building. The Photovoltaic installation of the country to an optimal efficiency for the year must be installed to the due south with an angle of thirty degrees. And also a module spacing must be more than doubled from the bottom to the top of module to prevent from efficiency falling by a shadow of photovoltaic module in a roof setting of flat roof. If Photovoltaic module is an adequate material that is a basic requirement as a building's finishing material, it's not only an efficiency of alternation with an existing finishing material but also a building's design element.

  • 본 논문에서는 $0.35{\mu}m$ CMOS 공정을 이용하여 태양 에너지 하베스팅을 위한 에너지 관리 시스템을 설계하였다. 태양 에너지 관리 시스템은 ISC(Integrated Solar Cell), voltage booster, MPPT(Maximum Power Point Tracker) control unit으로 구성된다. ISC의 개방전압은 약 0.5V이고, 단락 전류는 약 $15{\mu}A$이다. Voltage booster는 뒷단에 약 1.5V로 승압된 전압을 공급한다. MPPT control unit은 ISC가 MPP점에 도달 하였을 때, load로 전력이 전달될 수 있도록 pMOS 스위치를 동작시킨다. SEMU(Solar Energy Management Unit)의 크기는 패드를 포함하여 $360{\mu}m{\times}490{\mu}m$이다. ISC의 면적은 $500{\mu}m{\times}2000{\mu}m$이다. 제작된 칩을 측정한 결과 설계된 SEMU가 ISC에서 수확된 에너지에 대해 MPPT control 동작을 제대로 수행하는 것을 확인하였다. 측정된 MPP 전압범위는 약 370mV∼420mV이다.
