A solar cell module with a simple configuration and high efficiency is provided. A solar cell module of the present invention is configured by electrically connecting a plurality of solar cell elements. Each of the plurality of solar cell elements includes a plurality of first connection parts representing wiring connection parts in a first electrode and a plurality of second connection parts representing wiring connection parts in a second electrode on the same surface. A first solar cell element and a second solar cell element arranged adjacent to each other have portions of the plurality of first connection parts of the first solar cell element and the plurality of second connection parts of the second solar cell element connected by a wiring having a linear form in plan view.

Solar cell module

A solar cell module comprises a plurality of solar cell elements including a front surface electrode and a wiring member electrically interconnecting the solar cell elements. The front surface electrode includes a bus bar electrode and finger electrodes, the finger electrodes including a plurality of first finger electrodes and connected to the bus bar electrode, and a plurality of second finger electrodes not connected to the bus bar electrode. The front surface electrode further includes a fine wire electrode that is disposed in a region extending from the bus bar electrode in a longitudinal direction of the bus bar electrode and that is electrically connected to the second finger electrodes, the fine wire electrode including first and second fine wire electrodes intersecting to each other. The wiring member is connected to an intersection of the first and second fine wire electrodes and to the bus bar electrode.

Disclosed are: a printing plate having improved productivity; and a method for manufacturing a solar cell element, which uses the printing plate. A printing plate according to one embodiment of the present invention comprises: a metal plate; a buffer layer that is arranged on one main surface of the metal plate; and a slit that penetrates through the metal plate and the buffer layer. The slit has a first penetrating part that is located in the metal plate, a second penetrating part that is located in the buffer layer, and a bridge that is arranged inside and across the first penetrating part. When viewed in plan from the above-mentioned main surface side, the buffer layer-side opening edge of the first penetrating part is inside the metal plate-side opening edge of the second penetrating part.
