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.

摘要： Disclosed is a method for manufacturing a thin-film solar cell using plasma between a couple of parallel electrodes. In the method, a base member is placed in a chamber between a first electrode and a second electrode facing each other. A hydrogen gas is heated, and thus heated hydrogen gas and a silicon-based gas are introduced into a space between the first electrode and the second electrode. A ratio of a flow rate of the heated hydrogen gas to that of the silicon-based gas is at least 25 and no more than 58. A plasma is generated between the first electrode and the second electrode by applying high-frequency power to the second electrode while a pressure in the chamber is 1000 Pa or higher, and an optically active layer containing crystalline silicon is deposited on the base material.
