NOVELTY - The base i.e. shorting tray (201), has an enclosure fastening a dye sensitized solar cell (211) at a predetermined position in a predetermined posture relative to the enclosure. A shorting circuit shorts two poles of the dye sensitized solar cell fastened to the enclosure. The enclosure is formed with conductive material to serve as the shorting circuit. The shorting circuit includes a resistor having predetermined resistance that permits as large current flow possible to an extent that the dye sensitized solar cell is not being damaged.    USE - Base for use in a packaging container for fastening a dye sensitized solar cell (all claimed) i.e. photoelectric conversion element, that is utilized for converting sunlight into electric energy, at a predetermined position in predetermined posture relative to an enclosure of the base. Uses include but are not limited to manufacture, inspect, store and transport the solar cell.    ADVANTAGE - The base shorts the power collection sections of the different poles of the solar cell to be fastened, thus minimizing polarization in the solar cell, and hence minimizing the deterioration of the power generation characteristic of the solar cell. The base can be formed with a conductive material, and the enclosure can fasten the solar cell and serve as a shorting circuit adapted to come in contact with and short the power collection sections of the two poles of the fastened solar cell, thus providing a reduced number of components of the base, and hence facilitating the manufacture of the base in cost-efficient manner, and the packaging of the solar cell. The base can stably fastens the dye sensitized solar cell at the predetermined position in the predetermined posture relative to the enclosure of the base.    DETAILED DESCRIPTION - The conductive material is made of metal selected from a group consisting of steel and copper, carbon-containing plastic, aluminum evaporated plastic and wood and paper coated with conductive paint.
