Title:
PHOTOVOLTAIC ELEMENT AND FABRICATING THE SAME
Document Type and Number:
Japanese Patent JPS55117287
Kind Code:
A
Abstract:
PURPOSE:To provide an excellent and inexpensive electrode for a photovoltaic element by adding In to silver conductive paint which is regarded as being improper for the electrode of II-VI group compound semiconductor. CONSTITUTION:An n-type CdS sintered film 2 is formed on a glass substrate 1, and a CdTe sintered film 3 is selectively laminated thereon the form an electrode 4 on the film 2. The electrode 4 contains silver conductive paint and predetermined amount of In powder added to the paint. Sintered copper is diffused in the electrode 5 by employing paste containing graphite carbon powder containing copper ion organic binder added thereto on the film 3, and lead wire 7 is connected with silver conductive paint. Before hardening the electrode 4, the lead wire 5 is adhered thereto, and then paste is hardened to be connected. When the electrode 4 is formed with such material, it is brought into contact with the ohmic CdS layer 4 to provide rigid adhered state readily with lead wires. In addition, no deterioration of characteristics occurs at the element with inexpensive material cost.
