USAF Unmanned Aerial Vehicles to Run on Solar Power

A team of US scientists are working on a new generation of airborne solar cells, and expects them to power Air Force unmanned aerial vehicles (UAVs) in the near future.

The University of Washington’s Multidisciplinary University Research Initiative (MURI) project team, believe that their new breed of Dye-sensitized solar cells (DSSCs) will become an optimum energy harvesting source that may lead to longer flight times without the need to refuel.

According to lead researcher Dr. Minoru Taya, “These kinds of solar cells have more specific power convergence efficiency (PCE), very clean energy and easy scalability to a larger skin area of the craft, as well as low-temperature processing, which leads to lower costs overall.”

Chinese and Swiss researchers announced earlier this week that they have reached the highest efficiency yet for dye-sensitized solar cells (Grätzel cells). The photovoltaic cells are cheaper than silicon-based solar cells, but until this week’s discovery their drawbacks have outweighed their benefits.
