Abstract:
1. A betavoltaic cell semiconductor device, said betavoltaic cell semiconductor device comprising: a substrate; a positive metal contact; wherein said positive metal contact goes through said substrate, from front of said substrate to back of said substrate; said positive metal contact is located near a first side of said substrate, along said first side of said substrate; a negative metal contact; wherein said negative metal contact goes through said substrate, from said front of said substrate to said back of said substrate; said negative metal contact is located near a second side of said substrate, along said second side of said substrate; said first side of said substrate is located opposite to said second side of said substrate; a first electrical insulator jacket; said first electrical insulator jacket goes through said substrate, from said front of said substrate to said back of said substrate; said first electrical insulator jacket covers said positive metal contact and isolates said positive metal contact from said substrate in all directions except for said front of said substrate; a second electrical insulator jacket; said second electrical insulator jacket goes through said substrate, from said front of said substrate to said back of said substrate; said second electrical insulator jacket covers said negative metal contact and isolates said negative metal contact from said substrate in all directions except for said back of said substrate; wherein said substrate is made of semiconductor material; a radioisotope source layer; said radioisotope source layer is located on top of said substrate, on said front of said substrate; said radioisotope source layer is located between said first electrical insulator jacket and said second electrical insulator jacket, in middle of said substrate; wherein said negative metal contact is connected to a second negative metal contact of a second device; wherein said positive metal contact is connected to a second positive metal contact of said second device.
