A folded-type amorphous silicon photovoltaic battery pack which can be suspended

Abstract

The invention discloses a folded-type amorphous silicon photovoltaic battery pack which can be suspended. The battery pack includes a photovoltaic battery panel and an output line electrically connected thereto. The photovoltaic battery panel comprises a plurality of amorphous silicon photovoltaic batteries and a transparent conductive layer; the plurality of amorphous silicon photovoltaic batteries is distributed on the transparent conductive layer through the Miura folding method to form a photovoltaic battery pack for power to be output; the flexibility of the transparent conductive layer makes the battery pack easy to expand or fold through the Miura folding method; and the transparent conductive layer is a ZnO-based TCO transparent conductive film, of which the two surfaces are attached with PET transparent adhesive tape protective layers. The Miura folding method makes the entire photovoltaic battery pack very easy to expand and fold. The entire photovoltaic battery pack can be expanded as long as the opposite angles of the photovoltaic battery pack are stretched. The entire photovoltaic battery pack can be put in place within two seconds, thereby reducing the battery occupation space. The photovoltaic battery pack can be dismounted.

Description

technical field [0001] The invention relates to a suspendable and foldable amorphous silicon photovoltaic cell group. Background technique [0002] Today's photovoltaic cell technology is very mature, and amorphous silicon thin film cells have been developed and perfected. However, at present, the power generation efficiency of photovoltaic cells is low. In order to improve the charging efficiency of equipment, most portable photovoltaic power supply equipment expands the area of ​​thin-film batteries as much as possible, so as to increase the area for absorbing light. But this makes the device appear bulky. [0003] In order to increase the area, some portable photovoltaic devices use square folding links to fix photovoltaic cells on soft substrates (such as non-woven fabrics) (CN201520995250), so that the photovoltaic cell group can be folded, thereby reducing the volume and making it easy to carry and use. However, this folding method has a low utilization rate of spac...
