Title: Manufacture of solar cell
Inventor: SUDA KOICHI
IPC: H01L31/04
Filed: 1986-12-08
Abstract: PURPOSE:To improve spectroscopic sensitivity on the side of short wavelength, to prevent decrease in lifetime of a substrate in heat treatment, to decrease the recombination speed at the surface of a light receiving plane and to improve throughput, by implanting ions through an oxide film layer located on the surface of a substrate, forming a junction deeply at the electrode part of the light receiving plane other than a bypass, forming the junction shallowly at a light receiving part, and utilizing the oxide film as a protecting film in heat treatment. CONSTITUTION:In ion implantation, the amount of implantation in a substrate can be controlled by changing the thickness of an oxide film on the surface of the substrate. In consideration of this fact, ions are implanted into a part other than an oxide film 2 where finger electrode parts 6 are provided on a surface electrode part of a light receiving plane. A deep junction having a low sheet resistance is formed at this part. Meanwhile, the ions are implanted through the oxide film 2 into a part which is to become a light-receiving part, and a shallow junction is formed. The oxide film 2 is made shallow at a part where the light-receiving part and a bus bar 7a are formed. Thus a surface recombination speed is further decreased. The oxide film 2 is also utilized as a protecting film for preventing the decrease in lifetime in heat treatment of the oxide film 2. The film 2 is used as a passivation film for decreasing the surface recombination speed of the light receiving plane. The throughput is increased, and a highly efficient solar cell is obtained in this way.

IPC: C22C47/08
Filed: 1989-11-10
Abstract: The present invention relates to a novel method for forming metal matrix composite bodies. Particularly, a permeable mass of filler material is formed into a preform (3). The preform material (3) can then be placed onto the surface of or into a matrix metal alloy (4), whereupon the matrix metal alloy (4) spontaneously infiltrates the preform (3). After substantial complete infiltration of the preform (3), the preform (3) begins to at least partially sink into the matrix metal alloy supply. The matrix metal (4) which has infiltrated the preform (3) is then allowed to cool, thus forming a metal matrix composite body (6).
