SOLAR CELL EXAMINATION APPARATUS AND TRANSFER DEVICE FOR EXAMINATION DEVICES

摘要

A solar cell examination apparatus for examining a solar cell by applying a current in the forward direction to the solar cell thereby to cause EL emission of the solar cell is disclosed. The examination apparatus has a simple structure and is produced at low cost. A transfer device for transferring a stack of constituent members of a solar cell to be measured before lamination thereof to the examination apparatus is also disclosed. The stack of the constituent members is prevented from being displaced. The solar cell examination apparatus includes a dark chamber (110) having an opening (or a transparent plate) (112) in the top surface, a support means which is provided on the top surface (111) of the dark chamber and on which an object to be measured is placed, and a camera (120) provided inside the dark chamber (110). The solar cell examination apparatus further includes a light-shielding cover for interrupting light entering the dark chamber through the opening and through the gap between the opening (112) and the solar cell placed on the support means. The transfer device includes a pair of lines of transfer members (two lines) connected in an endless form in the transfer direction. Each transfer member has a wall lower than the thickness of the stack of the constituent members such as a transparent substrate of the solar cell being transferred. The two lines of transfer members guide the stack of the constituent members to prevent the constituent members from being displaced during the transfer.
