碩士 === 國立臺北科技大學 === 製造科技研究所 === 101 === This study designed two different dye-sensitized solar cell structures, these two design methods have a three-dimensional structure of the light anode, respectively closed and open cell battery. The aim is to increase the area of the photoelectrode film, in a fixed area of the illumination area of the light to enhance, improve photoelectric conversion efficiency in order to achieve the purpose. Consideration closed cell design experiments in order to prove that the direction the dye-sensitized solar cell on the basis of the three-dimensional structure is established, production methods of this experiment is to 5 of indium tin oxide coated conductive glass anode structure stack synthesized light, glass spacing to 300 μm; electrolyte using a liquid electrolyte, the counter electrode is a conductive foil thickness 300 μm, encapsulation method is to use a height of 10 mm to 15 mm acrylic sheet bonding together a complete package, according to the solar light simulator machine actual measurements, voltage measurement curve can be reached - Current fourth quadrant of the coordinate axes, although the photoelectric conversion efficiency is poor, but the feasibility of the experimental results confirmed. Open the battery are designed to improve Enclosed battery, its way of making a lot of dollars, mainly using graphite paper, carbon sink and counter electrode materials such as platinum, and then do measurements in different dimensions, electrolyte using colloidal electrolyte package method is simple package. Pt counter electrode material is laminated three-dimensional cell film applied experimental results show, according to the light-receiving area of 0.28 cm2, cell height of 7 mm, the open circuit voltage can be obtained 0.662 V, short circuit current density 18.42 mA/cm2, fill factor of 0.31, the photoelectric conversion efficiency 3.85%, for the three-dimensional vertical 1.65 times the battery and the battery is flat 2.15 times.
