Embodiment Construction
[0025] The technical scheme of the present invention will be further explained below in conjunction with the drawings.
[0026] The metal wire film includes a plurality of metal wires 100 arranged in parallel, and a composite film that is sequentially staggered on opposite sides of the plane formed by the multiple metal wires 100 by hot pressing. The composite film is provided with an even number. In this embodiment, The composite film is an electrically insulating optically transparent film. The composite film includes an upper composite film 200 located on one side of the plane and a lower composite film 300 located on the other side of the plane. There is a separation distance between the adjacent upper composite film 200 and the lower composite film 300. In this embodiment, the upper composite membrane 200 and the lower composite membrane 300 are the same.

The invention discloses preparation equipment for a metal wire film of a solar cell. The metal wire film comprises multiple strands of metal wires arranged in parallel, and composite films sequentially arranged at the two opposite sides of a plane formed by the metal wires in a staggered mode in a hot pressing mode. The composite films comprise an upper composite film positioned at one side of theplane and a lower composite film positioned on the other side of the plane. The equipment comprises a metal wire unwinding mechanism, a traction mechanism, an upper composite film hot-pressing mechanism used for hot-pressing bonding of an upper composite film and a metal wire, and a lower composite film hot-pressing mechanism used for hot-pressing bonding of a lower composite film and multiple strands of metal wires. The equipment is simple in structure, enables the composite film and the multiple strands of metal wires to be bonded to form the continuous metal wire film through heating, simplifies the production process, improves the production efficiency, reduces the consumption of silver paste, greatly reduces the cost, and improves the light transmittance of the composite film, thereby improving the stability and the capacity of a photovoltaic cell.
