(OTAs) is crucial for designing highly efficient antennas that can be integrated with
photovoltaics. Transparent Conductor Oxides are promising for OTA fabrication due to their
capability of being simultaneously transparent at optical frequencies and conductive within
the radio frequency (RF) range. Here in this study, thin aluminum and zinc oxide layers were
co-sputtered onto Si and a polycrystalline photovoltaic cell and then annealed between 350 …
