Document Type and Number:
Japanese Patent JP2002532888
Kind Code:
A
Abstract:
Disclosed is a thin-layer solar cell array system and a method for producing the same, having placed over a carrier substrate of plane design, a solar cell layer which is provided with at least one n-type conducting semiconductor zone (emitter) and at least one p-type conducting semiconductor zone (base) as well as a first and a second contact electrode, each of different electric polarity, which are each electrically connected to the emitter respectively to the base.The invention is distinguished by at least the first contact electrode being applied directly on the carrier substrate or separated by an electrically insulating layer, an electrically insulating layer being provided thereupon, and the solar cell layer being placed over the insulating layer, by at least one contact channel extending through the insulating layer and/or the solar cell layer in such a manner that the first contact electrode and the semiconductor layer zone of respective polarity inside the solar cell layer being electrically connectable by means of an electrically conducting material provided inside the contact channel, and by the second contact electrode like the first contact electrode being placed above or in the case of a conductive carrier layer also under the carrier layer and under the electrically insulating layer and the solar cell layer, and by at least one contact channel extending through the insulating layer and/or the solar cell layer in such a manner that the second contact electrode and the semiconductor layer zone of respective polarity inside the solar cell layer being electrically connected by means of an electrically conducting material provided inside the contact channel.
