PV products applied to BIPVs about 99 % of all products in silicon solar cells. Although the initial BIPVs were simply attached to the roof or walls of the building, it caused problems that damaged the appearance of the building. To solve this problem, recently the application of the Dye-sensitized Solar Cell(DSSC) is increased. DSSC have a lower manufacturing cost and permeability than crystallized solar cells and do not rise the room temperature above 25 °C. DSSC can be colored and permeable depending on the dye used, showing excellent aesthetic characteristics when attached to windows or exterior walls. In these days, the studies for DSSC such as efficiency improvements and reliability tests have been conducted. In this study, the optical characteristics of the red DSSC module are analyzed and the complementary colors are calculated to improve the color reproducibility that affects the users work surface comfort. CIE color coordinates were converted into RGB codes, and complementary colors were calculated using the converted codes.

The efficiency and life time of the proton exchange membrane (PEM) fuel cell system is critically changed with its humidity which should be maintained properly during dynamic operation. Membrane humidifier is required to regulate proper humidity level for the design point of the PEMFC system. In this study, we presented the performance of the cylindrical membrane humidifier which is operated as water-to-gas. Dry air pressure, liquid water flow temperature, and air flow rate were chosen as the operating parameters. Humidity level is expressed with dew point.

An LED (light emitting diode) has the advantages of lower power consumption, energy saving, high efficiency, long lifetime, and environmental friendliness so that it has been getting the spotlight as a next-generation light source. Thus, the application range of an LED has been extended to various fields including indoor and outdoor lighting. Recently, the high efficient LED lighting has been developed, an LED has been extended its market rapidly every year and is expected to replace the general light source within near future. In this study were measured electrical and optical properties for 6 types of LED bulbs which are being developed to replace the general incandescent lamps, and were analysed under the standard of the omnidirectional lamp required by the Energy Star.
