The Characteristic Analysis of the Dye-sensitized Solar Cells as the Change of Incident Angle

Dye-sensitized solar cells (DSCs) have been proposed as a substitute for overcoming the limitation of Si solar cells because DSC has the various applications using advantages of DSC such as low cost, transparency and flexibility. Although some people point out low efficiency of DSC as the important problem at present, general views say that actually cumulative power is not insufficient as compared with Si solar cell. Therefore, we analyzed the characteristics of both cells according to the change of incident angle in this study. The insensibility about the incident angle has more developable time. Finally, DSC is able to fill a shortage of power caused from low efficiency of DSC for same time by developing during impossible time to develop in Si solar cell. As a result, DSC has 75% and 210% cumulative power of Si solar cell in summer and winter under the standard sunshine duration.
