Abstract
A voltage-matched solar module for converting incident solar radiation into electricity consisting of a plurality of wafer-sized multi-junction solar devices and wiring circuitry adjacent to a module-sized bottom substrate. Each solar device has at least two photovoltaic (PV) cells separated by electrically insulating transparent layers. The PV cells are aligned so as to overlap and are electrically connected to the wiring circuitry by conducting vias. The wiring circuitry includes a multiplicity of serial strings electrically connected in parallel and having substantially the same voltage. A method of producing the solar module is disclosed which utilizes an ALD/LPCVD tool for van der Waals epitaxy of 2D materials.
