TL;DR: In this paper, the bus bar electrodes are used to retrieve light-produced current produced at the solar cell element to the outside and collecting finger electrodes connected to these bus bars, and the finger electrodes (5b) are 0.5 mm through 2 mm in width and the bus-bar electrodes were 0.05 mm through 0.1 millimeter in width.

TL;DR: In this article, the authors proposed a solar battery element which suppresses increase in the series resistance of a first current-collecting electrode, mainly made of an aluminum and a second current collector made of a silver to maintain the output characteristics and relax the warpage of the battery.

TL;DR: In this article, a solar cell element has the surface electrode on the light receiving face-side of a semiconductor substrate of polycrystalline silicon, and the surface area of a region where the surface electrodes is arranged to be Sb (cm 2 ) in the light receptive face of the solar cells element, a relation of 1.10≤Sb/Sa≤2.

TL;DR: In this article, the authors proposed a solar battery element which can reduce gas content between electrodes and an inner lead 8 while keeping electrode strength between a semiconductor substrate 1 and bus bar electrodes (4a, 5a) in a photo-sensitive surface side and/or a non-photosensitive surface side thereof.

TL;DR: In this paper, an optoelectric conversion element comprising a p-type crystalline Si semiconductor, n-type semiconductor (4) to form a pn junction portion by joining the crystalline si semiconductor and an electrode (1) provided on the n type semiconductor was presented.
