[0029] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0030] Such as figure 1 with figure 2 As shown, the conventional packaging process for ordinary black photovoltaic modules is:
[0031] First, use a series connection tape 2 (such as tinned copper tape) to weld multiple photovoltaic cells 1 in series to form a battery string;
[0032] Then lay the glass 3 flat on the production line, which is used for the front protection of photovoltaic modules; lay EVA material on the glass 3 as the laminating glue 4;
[0033] Next, the front of each battery string is facing the glass 3 for layout, and each battery string is arranged in parallel, leaving a gap of 2 to 3 mm between the strings; the battery string 3 is connected by welding with the string using a bus bar;
[0034] Laminate glue 5 on the back of all battery strings after typesetting; Laminate glue 5 also uses EVA material;
[0035] Then lay the black backing sheet 6 on th...
