摘要:
An electrical connector for electrically connecting multiple photovoltaic bus bars. A casing includes first and second opposing walls. An elastic strip is bent into a bent elastic strip with a first leg and a second leg. The bent elastic strip is disposed between the first and second walls of the casing with the first leg pressing against the first wall and the second leg pressing against the second wall. The bent elastic strip is configured to hold at least one of the photovoltaic bus bars between the first leg and the first wall and another of the photovoltaic bus bars between the second leg and the second wall. The bent elastic strip may be formed of resilient spring metal with a thickness and an elastic modulus. The thickness and/or the elastic modulus of the elastic strip is/are configured so that the bus bars are inserted without requiring a tool to open a space and so that the bus bars are removed from the connector without requiring a tool to break the electrical connection.

The invention relates to a thin-film solar cell module (71) in which a layer (72) of TCO is applied on a glass substrate (73). On this layer (72) of TCO is disposed a semiconductor layer (75) on which is applied an electrically conducting backside layer (85). The backside layer (85) includes a bridge element (88) in contact with the layer (72) of TCO. Directly on the layer (72) of TCO are applied busbars (82) by means of a printing method. The busbars (82) are herein connected with the backside layer (85) via the layer (72) of TCO.

A solar cell includes: a front surface electrode having a first current-collecting electrode and non-straight line electrodes connected to the first current-collecting electrode; a semiconductor substrate serving as a photoelectric conversion body; and a rear surface electrode having a second current-collecting electrode and line electrodes connected to the second current-collecting electrode. The front surface electrode, the semiconductor substrate and the rear surface electrode are arranged in that order. The non-straight line electrodes of the front surface electrode and the line electrodes of the rear surface electrodes are opposed to each other with the semiconductor substrate interposed there-between. The non-straight line electrodes of the front surface electrode and the line electrodes of the rear surface electrodes are different in shape while having a portion where the electrodes intersect each other, as seen in a direction perpendicular to the front surface of the semiconductor substrate.
