Title:
SLICED CELL PHOTOVOLTAIC MODULE
Document Type and Number:
WIPO Patent Application WO/2021/051862
Kind Code:
A1
Abstract:
Disclosed is a sliced cell photovoltaic module, comprising one or more cell units connected in series, wherein each cell unit comprises one cell string sequence or a plurality of cell string sequences connected in series or in parallel; each cell string sequence comprises one cell string or a plurality of cell strings connected in parallel by means of a bus bar; and each cell string comprises a plurality of small cell slices connected in series by means of connection materials; the spacing between the plurality of small cell slices is -2 to 5 mm, wherein each small cell slice is one of 2-8 independent small cell slices obtained by means of laser cutting a solar cell with a size of 156*156 to 300*300, etc.; each small cell slice has a positive electrode and a back electrode; and the positions of each positive electrode and each back electrode are superposed with each other or are respectively at the edges of two ends of the small cell slice. According to the photovoltaic module of the present application, the module power is greatly improved, and a sharp increase in a short-circuit current of the module cannot be caused, such that the power loss cannot be increased, and a potential failure risk, caused by an increase in a rated current of a junction box, of the module can also be avoided.
