PV for UAV: a High-End Photovoltaic Application

Powering unmanned aerial vehicles (UAVs) with solar cells is one of my earlier projects that I submitted to DoD in 2005 for funding.  The focus of the project was to significantly enhance UAVs by adding photovoltaic modules and an on-board automaton for multi-source and multi-load energy management. Firefox UAV model, built by Advanced Ceramic Research Inc., was an excellent UAV platform for the purpose of my project. A large PV module was integrated with the UAV to enhance its mission and the operational capabilities, through powering more electronic instruments and increasing the mission duration.  I referred to the then new technology as "PV for UAV". My research group and I have focused on maximizing the harvested energy during the UAV mission, and optimizing the energy usage of the on board sensors of the mid-size Firefox UAV. A follow-up project funded by the Army Research Lab (ARL) was also carried out; it was titled:  "Third Generation Photovoltaic Cells for Autonomous Sensors".

Thin Film Solar Cells for the "PV for UAV" Technology

Materials Science and photovoltaic research topics in photovoltaics (PV) for PV systems intended to power UAVs are still some of my R&D areas of interest. This research started with an earlier projects in 2005-2006 funded by DoD-NAVAIR. The focus was for powering unmanned aerial vehicles (UAVs) with high efficiency solar cells. The research them was: use of Multi-Source energy system and on-board energy management for extending the mission of Unmanned Aerial Vehicles in duration and functionalities. The title of the NAVAIR sponsored project was "Photovoltaic Power Supply for autonomous Sensors".

Terawatt Photovoltaic Energy Scenario, Dreams and Realities

The photovoltaic (PV) industry is promoting the idea of scaling-up photovoltaic technologies to produce deca-Terrawatts, some are even talking about hundreds of TWs. In many ways, they are right; but are these extreme ideas doable? If so, how to achieve them? Will these goals be met by only relying on silicon PV technologies? Realistically, how much could be achieved by 2050?
