摘要:
A process for producing a solar cell module comprising at least a photovoltaic element module is provided. The photovoltaic element module is formed by electrically connecting a plurality of photovoltaic elements with each other, after the individual photovoltaic elements are identified or classified into a plurality of groups which are different from each other in property and attribute. The photovoltaic element module is formed such that at least two kinds of photovoltaic elements having different property and attribute co-exist therein. A solar cell module having at least a photovoltaic element module comprising a plurality of photovoltaic elements electrically connected with each other is also provided; the plurality of photovoltaic elements comprises photovoltaic elements identified or classified into at least two kinds which are different in terms of property and attribute.

A photovoltaic element with a low shadow, a high energy conversion efficiency, a high freedom in dimension and a high reliability with prolonged use is provided. The photovoltaic element comprises a photovoltaic layer having a first semiconductor junction layer for generating an electromotive force, a current collecting electrode provided at the light incident side of the photovoltaic layer, and a bypass diode connected in parallel, wherein the bypass diode is provided under the current collecting electrode as a bypass diode layer having a second semiconductor junction layer other than the first semiconductor junction layer of the photovoltaic layer.
摘要:
A solar cell module has a very agreeable appearance and can carry a large volume of information on the light receiving surface thereof. An information carrying body storing information (including, for example, the date, the process the rated values, the destination of shipment, I-V curve data and other data) for identifying the module is invisibly arranged on the light receiving surface side of the solar cell module (e.g., on the front surface sealing member or the front surface member of the photovoltaic elements).
摘要:
A photovoltaic device is provided which comprises at least one metal wire on a surface of a photovoltaic element for collecting the power generated by the photovoltaic element, the at least one metal wire being coated with an electroconductive adhesive over the entire length and fixed onto the photovoltaic element. The photovoltaic device is produced without applying and curing the electroconductive adhesive in the photovoltaic device production process at low cost with high reliability.
