Solar cells (SCs) are the most ubiquitous and reliable energy generation systems for aerospace applications. Nowadays, III–V multijunction solar cells (MJSCs) represent the standard commercial technology for powering spacecraft, thanks to their high-power conversion efficiency and certified reliability/stability while operating in orbit.
A key conclusion is that the technology development trend in solar aircraft systems can be assessed based on the current technology endpoint of individual systems with significant impact on the overall aircraft. These have been identified in this review to be the energy storage system and the energy source system.
Overall trends in Solar Aircraft Efficiency The basic concept of a solar aircraft is a combination of systems which ultimately convert solar energy into electrical energy and then mechanical energy in order to do work. This work includes flight propulsion and powering on board avionics, sensors and electrical systems.
Solar energy has a large potential to be a major fraction of a future carbon-free energy portfolio in aviation. However, technological advances and breakthroughs are necessary to overcome low conversion efficiency and high cost of presently available systems.
The most important technical challenge that solar-powered aircraft is facing today is developing a system which is capable of not only harvesting enough energy for flight during the day, but to store enough energy during the day for sustained flight through the night until a new solar energy harvesting regime starts from sunrise the next day.
By way of definition, solar-powered aircraft could be described as aerial vehicles capable of sustained level flight in the atmosphere depending solely on solar radiation impacting on its airframe as its primary energy source. The design and development of solar-powered aircraft has gained an increasing level of interest in the last 30 years.
