Abstract
A photovoltaic device is disclosed herein that, in various aspects, includes a conductive layer, and a substantially crystalline lamina with a first surface oriented toward the conductive layer and a second surface oriented away from the conductive layer. The lamina thickness is within the range between about 0.2 microns and about 50 microns. An aperture passes through the lamina from the first surface to the second surface. A connector in electrical communication with the conductive layer is disposed through the aperture. Methods of manufacture of the photovoltaic devise are also disclosed.
Claims19
A photovoltaic device, comprising:
- a conductive layer;
- a substantially crystalline lamina with a first surface oriented toward the conductive layer and a second surface oriented away from the conductive layer, and the lamina thickness being within the range between about 0.2 micron and about 50 microns;
- an aperture that passes through the lamina from the first surface to the second surface;
- and
- a connector in electrical communication with the conductive layer and disposed through the aperture.
A method of manufacture of a photovoltaic assembly, comprising the steps of:
- providing a conductive layer;
- providing a substantially crystalline lamina with a first surface oriented toward the conductive layer and a second surface oriented away from the conductive layer, and the lamina thickness being within the range between about 0.2 micron and about 50 microns;
- forming an aperture passing through the lamina from the first surface to the second surface;
- and
- attaching a connector within the aperture in electrical communication with the conductive layer.
The method, as in claim 17, further comprising the step of doping the donor wafer through the donor wafer surface prior to implanting step.
