Abstract: A solar cell inside a photovoltaic (PV) panel inherently produces dc output which needs to be processed and
inverted for ac applications. Using a modern manufacturing facility, PV panels could be mass produced without any
apparent issues. Unfortunately, power converters used in PV systems are still made of discrete components and are not
suitable for mass production. The power engineering and automation research lab (PEARL) team at University of Utah
aims to introduce a breakthrough technology to generate 120V/240V ac output directly from the panel. Therefore, the
individual PV strings inside the panel would produce ac output rather than dc. All circuit components are embedded on the
same substrate material (for now, this is rather expensive single crystal Si, ultimate integration will be done with least
expensive thin film or poly-Si) to integrate both the PV cells and the converter unit without using any discrete components
and interconnections.
The proposed silicon processing technique will provide a guideline for solar cell designers to fabricate various discrete
