摘要： A solar cell including: a substrate having front and back surfaces, the back surface includes first, second and gap regions, the first and second regions are staggered and spaced from each other in a first direction, and each gap region is provided between one first region and one second region adjacent thereto by recessing toward interior of the substrate; a first conductive layer formed over the first region; a second conductive layer formed over the second region, the second conductive layer has a conductivity type opposite to the first conductive layer; a first electrode forming electrical contact with the first conductive layer; a second electrode forming electrical contact with the second conductive layer; and a boundary region between the gap region and the first and/or second conductive layer adjacent thereto, and a line-pattern concave and convex texture structure is formed on the back surface corresponding to the boundary region.

摘要： Provided is a busbar-free interdigitated back contact (IBC) solar cell and an IBC solar cell module. The IBC solar cell includes a semiconductor substrate, finger electrode lines and conductive lines. The finger electrode lines include first finger electrode lines and second finger electrode lines that are alternately arranged on the semiconductor substrate. The conductive lines include first conductive lines and second conductive lines that are alternately arranged. The first conductive lines are connected to the first finger electrode lines and spaced apart from the second finger electrode lines. The second conductive lines are connected to the second finger electrode lines and spaced apart from the first finger electrode lines.
