The purpose of this study was to review in available DSSC(Dye Sensitized Solar Cell) for architectural window system in the field of condition of lighting. For this examination, firstly, inside daylighting performance was analysed at the suggested building model which was mounted DSSC window instead of existing clear window. Secondly, it drew up objective data in the preferred pattern of DSSC colors in related to psychological stability and capacity for work. First of all, the result of the inside illunimance and DF for performance of natural lighting was satisfied with standard value as minimum acquired illuminance 400Lux and recommended DF 4% in office domain. In assessment of uniformity of ratio by season and orientation, its alteration was not so great in 3% by building orientation inserted DSSC window and satisfied with 10% of standard from lateral daylighting, but it had big deviation by type of DSSC window. Next, in preferred visual color of DSSC window by making 3D graphic image, the space of Sky Blue dye color had first preference of 13.3% and the space Red dye color had lowest of 5.0% on the questionnaire. The sincerity of survey was assessed at high value as 97.3%
