Abstract
A multilayer device for producing electricity. The device comprising a betavoltaic source layer for generating beta particles, and at least three semiconductor layers each having a bandgap substantially similar to a band gap of the other layers, the at least three layers comprising a doped top layer, an undoped intermediate layer and a doped bottom layer, wherein the top and the bottom layers are doped with opposite-type dopants, and wherein the top layer is closer to the betavoltaic source layer than the bottom layer.
