Abstract: A heterojunction cell includes: a cell sheet, the cell sheet being provided with a front face and a back face, which are arranged opposite each other; screen-printed grid lines, the screen-printed grid lines being made of silver paste and being arranged on the front face and the back face of the cell sheet; and a metal mesh, the metal mesh being connected to the screen-printed gate lines and being fixedly arranged on the cell sheet.

Abstract: A photovoltaic module includes a cell string, transparent insulated flexible protectors, a front adhesive film, a back adhesive film, a first plate, a second plate. The cell string includes multiple cells. Adjacent cells are connected in series through multiple spaced welding ribbons. The area on the surface of each cell without the welding ribbons is a mounting portion. Adjacent cells are staggered vertically. The protector is arranged on the front or back side of each cell. The protector includes a first protective portion connected to the surface of the mounting portion, and a thickness of the first protective portion is not less than thicknesses of the welding ribbons. The front adhesive film and the back adhesive film are respectively connected to the front side and back side of the cell. The first plate and the second plate are connected to the front adhesive film and the back adhesive film, respectively.

Abstract: Disclosed are a shingled cell, a cell unit, and a shingled photovoltaic assembly. The cell unit includes a cell. The front side of the cell includes a plurality of parallel front-side fine grid lines. The back side of the cell includes a plurality of parallel back-side fine grid lines and a front-side connection line. The front-side connection line is a continuous or non-continuous line segment. The front-side connection line is arranged on at least one side of the cell. The front-side connection line is connected to the ends of all the front-side fine grid lines on the same side. The front-side connection line is such configured that when two cell units are overlapped along the extension direction of the front-side fine grid lines, the front-side connection line of the lower cell unit contacts each of the back-side fine grid lines of the upper cell unit.

Abstract: The present disclosure describes methods of forming a colored conductive ribbon for a solar module which includes combining a conductive ribbon with a channeled ribbon holder, applying a color coating to at least the conductive ribbon within the channel, curing the color coating on the conductive ribbon, and separating the conductive ribbon from the channeled holder.

Abstract: A method of forming a solar module. The method includes etching a solar cell, singulating the cell to form strips, and depositing a conductive adhesive on at least one portion of the singulated strips. The strips are then arranged with the conductive adhesive in a shingled manner to form strings of strips such that a portion of each strip overlaps with a portion of the next with the conductive adhesive forming a bond between adjacent strips. A plurality of strings are then connected electrically in parallel to form a set of strings, and a plurality of sets of strings are connected electrically in series. The sets of strings are encapsulated between a front glass and a backsheet and mounted in a frame to form a solar module.
