Problems solved by technology

This connection method is very troublesome and time-consuming
At the same time, the use of cables for connection and the protection and fixing of cables will also increase the cost of the solar battery system
[0016] In addition, when the back side of the battery module is visible, there are junction boxes and output cables on the back side of the battery module, which makes the back side of the battery module unsophisticated and unsightly

Abstract

A thin-film solar photovoltaic cell module comprises a cell panel and a connecting box. The cell panel is provided with a cell plate layer and bus bars, wherein the cell plate layer is formed by a plurality of cell plates extending longitudinally and in transverse series connection, and the bus bars extend along two longitudinal extending edges of the cell panel respectively. The connecting box is arranged along a transverse extending edge of the cell panel and comprises a box body and a connecting circuit. In the connecting circuit, a conductive wire extends along the transverse extending edge and at least partially extends out of the box body, a bypass diode in the box body is connected in the conductive wire so as to prevent the cell panel from disconnection or reverse current, the two bus bars arranged on two sides of the diode are connected to the conductive wire, a male connector and a female connector which are on two sides of the diode are connected to the conductive wire so as to realize external connection, and the two bus bars are directly connected to two ends of the connecting circuit at the two ends of the transverse extending edge of the cell panel. The thin-film solar photovoltaic cell module is attractive, easy to mount and maintain with less use, fixation and protection of cables and not easy to be damaged.

Description

technical field [0001] The present application relates to a thin film solar cell module having a junction box arranged along the laterally extending edges of the panels. Background technique [0002] Recently, thin-film solar cells have become a new trend and new hotspot in the field of solar cells (photovoltaic cells) due to their low silicon consumption, low cost, and high efficiency. The types of thin-film solar cells mainly include amorphous silicon thin-film solar cells, microcrystalline silicon thin-film solar cells, dye-sensitized dye thin-film solar cells, organic thin-film solar cells, copper indium selenium thin film solar cells, copper indium gallium selenium thin film solar cells, tellurium Thin-film solar cells, etc. [0003] figure 1 A common thin-film solar cell module is shown in , which is mainly composed of a cell panel 10 , a frame 30 surrounding the periphery of the cell panel, and a junction box 50 for outputting electric energy generated by the cell p...
