  • Publication number: 20110083719
    Abstract: The present invention relates to an electronic device configured to make use of features in terms of design quality and flexibility of a dye-sensitized solar cell. A solar cell-cum-display unit 61 has both a function of a solar cell and a function of a display unit that displays a predetermined display body, allows a predetermined character string such as “PONY” to be indentified, generates electric power from illuminating light or sunlight, and stores the electric power in a storage battery 62. A light source 63 such as a fluorescent lamp radiates light to the solar cell-cum-display unit 61 by the electric power stored in the storage battery 63, whereby the features of the dye-sensitized solar cell can be made use of. The present invention is applicable to a device including a dye-sensitized solar cell.

  • Publication number: 20100144083
    Abstract: The present invention relates to a method of manufacturing a photoelectric conversion device in which selective dye adsorption can be performed easily. In the step of a dye adsorbing process, a material unit 21 having partition walls of a predetermined shape is placed over semiconductor electrodes 121 to 123, which are a titanium oxide electrode. The material unit 21 is laminated by a UV cure adhesive. Dye solutions S1 to S3 obtained by dissolving each of three kinds of dyes of N719, Black dye, and D149, for example, into a CH3CN/t-BuOH mixed solution are put in each of sections divided by the partition walls. The material unit 21 is inverted in that state, and left standing still for 24 hours. Then, the adhesive is removed after passage of the 24 hours. Thus, the semiconductor electrodes 121 to 123 having regions corresponding to the sections which regions are colored with the three different kinds of dyes are obtained.
