Title:
THIN FILM SOLAR BATTERY
Document Type and Number:
Japanese Patent JPS5994881
Kind Code:
A
Abstract:
PURPOSE:To form a stable series connection type thin film solar battery whereto a reverse parallel diode is added without increasing a photo power generating reactive area by a method wherein the reverse parallel diode for protecting the thin film solar battery element in series connection is formed on a flexible metallic electrode and is then connected between each element and the upper electrode of adjacent elements. CONSTITUTION:Generally, ITO (indium tin oxide) film or SnO2 film is used for a plurality of clear electrodes 4 formed in isolation on a common clear insulation substrate 3. An a-Si pattern 5 with a P-layer, an I-layer, and an N-layer laminated from the substrate side is isolation- formed thereon. And, the metallic electrode 6 is formed thereon. The left side edge of the metallic electrode 6 in the figure is so formed as to overlap on the edge of the a-Si layer 5, and the right side is extended until it is electrically connected to the clear electrode 4. Thus, the solar battery elements are put in series connection. The exposed part of the metallic electrode 8 is adhered to the metallic electrode 61 of one solar battery element 11 with an adhesive such as conductive paste, and the metallic electrode 10 to the metallic electrode 62 of the adjacent solar battery element 12, and the protection diode 2 is connected to the solar battery element 1 in reverse parallel. A plurality of such protection diodes 2 are prepared on the common flexible film 7, which are then adhered on the solar battery elements prepared in a plurality on the common insulation substrate 3.
