摘要： A surface electrode (5) is installed on the light receiving surface of a solar cell element, the surface electrode (5) comprises three bus bar electrodes (5a) for extracting light-produced at the solar cell element to the outside and collecting finger electrodes (5b) connected to these bus bar electrodes (5a), and the bus bar electrodes (5a) are not less than 0.5 mm and not more than 2 mm in width and the finger electrodes (5b) are not less than 0.05 mm and not more than 0.1 mm in width. A high-efficient solar cell module can be obtained with substantially lowered resistance by increasing the number of bus bar electrode (5a) and thereby decreasing the lengths of the finger electrodes (5b).

摘要： In a photoelectric conversion device, in a contact between a p-type semiconductor 3a and an electrode 2, an n-type semiconductor 6 of a conductivity type opposite to that of the p-type semiconductor is provided between the p-type semiconductor 3a and the electrode 2. The existence of the n-type semiconductor 6 allows a recombination rate of photo-generated carriers excited by incident light to be effectively reduced, and allows a dark current component to be effectively prevented from being produced. Therefore, it is possible to improve photoelectric conversion efficiency as well as to stabilize characteristics. Further, a tunnel junction is realized by increasing the concentration of a doping element in at least one or preferably both of the p-type semiconductor 3a and the n-type semiconductor 6 in a region where they are in contact with each other, thereby keeping ohmic characteristics between the semiconductor and the electrode good.
