Abstract

The present invention provides a solar battery short circuit part removing apparatus which can remove the short circuit part fast; simultaneously, requirements to power supply specifications of reversed bias voltage range necessary to the removing of the short circuit part is not high, or damages generated by applied voltage during removing are prevented. The battery short circuit part removing apparatus of the present invention removes a short circuit part of a battery by applying a reversed bias voltage; the short circuit part comprises one or more solar battery units stacked with a first electrode, a photoelectric switching layer and a second electrode on a base plate in turn. The battery short circuit part removing apparatus is characterized in that the apparatus comprises a belt gap voltage set part to set belt gap voltages of one or more materials forming the photoelectric switching layer; a reversed bias voltage applying part regarding all the set belt gap voltages as the reversed bias voltage to be applied on two electrodes clamping the short circuit part.

Description

technical field [0001] The present invention relates to a device and method for removing a short-circuit portion of a battery, for example, a device and a method for removing a short-circuit portion (poor insulation portion) of a solar cell. Background technique [0002] When manufacturing thin-film solar cells using amorphous semiconductors, etc., short circuits may occur between the substrate-side electrode and the back-side electrode sandwiching the photoelectric conversion semiconductor layer for power generation, between two back-side electrodes, or within each layer department. For example, in a thin-film solar battery, a plurality of solar battery cells (cells) are arranged in parallel on one substrate. In the process of laminating the substrate-side electrode, photoelectric conversion semiconductor layer, and back-side electrode on the substrate, a plurality of solar cells are common, and thereafter, grooves (scribed grooves) for dividing adjacent solar cells are fo...
