“…While this thermal effect will be greater for c -Si due to its inferior temperature coefficient (−0.45%/°C) relative to CdTe (−0.17%/°C), spectral effects dominate such that CdTe modules should outperform Si underwater even when cooled. Finally, it is important to prohibit biofouling, i.e., the build-up of organic matter on the solar cell encapsulant ( Crimmins et al., 2006 ), as this will result in power loss as light can no longer reach the active materials inside the solar cell ( Ageev et al., 2002 ). Various antifouling approaches exist that can be explored for this purpose ( Cao et al., 2011 ).…”

“…The results reported here are preliminary, but they help define the unique characteristics of the SAUV II as it is built today. The results of this and other investigations [5] [6] [7] have allowed the establishment of an engineering database focused on the technologies to implement refinements in the SAUV II system. Work is currently underway to continue to evaluate performance through in-water experimentation and collaborative development efforts.…”

The solar-powered autonomous underwater vehicle (SAUV) was designed for long-endurance missions, such as monitoring, surveillance, or station-keeping, where real-time bidirectional communications to shore are critical. In April 2006, the Naval Undersea Warfare Center (NUWC) Division Newport, Falmouth Scientific Inc. (FSI), and Autonomous Undersea Systems Institute (AUSI) conducted a 30-day, long-endurance test using SAUV II primarily to demonstrate that the vehicle is capable of conducting long-term oceanographic data collection and to validate the vehicle's mechanical integrity. This test also served to evaluate possible anomalies and risk-reduction measures for future production-level vehicles. A key part of this long-endurance test was the logging of the SAUV II charge and discharge rates under different sky and weather conditions with the vehicle under varied energy load situations-data that can be used to assess vehicle endurance and help establish future mission capabilities of the SAUV II. This paper describes the SAUV II test vehicle, test methods, data collected, and the results of the long-endurance test.

“…Its power system consists of two Solarex (MSX30L) 30‐W solar panels and four batteries (32 NiCd cells) . In order to verify its endurance measurements in the ocean, SAUV I has undergone sea testing near Vladivostok for 22 days . On the basis of the successful test of SAUV I, AUSI, cooperating with Technology Systems Inc and Falmouth Scientific Inc, had developed the SAUV II, with 200‐kg weight, 2.3 m length, and 1.1 m wide, max operating depth of 500 m, speed of 0.75 to 3 knots, as shown in Figure A.…”

Summary The power supply for ocean robots has always been an important issue since it has a fatal influence on the endurance of these vehicles. However, the marine renewable energy (MRE) has huge potential and can provide the possibility to solve this problem between essential endurance and finite energy in ocean robots. This paper starts with brief introduction of marine energy resource and ocean robots and presents significance of improving ocean robots' endurance, through comparison of their performance characteristics. MRE applied in ocean robots developed or under development, including energy conversion and driving principle, is reviewed, such as solar, wind, tides, waves, thermal energy, etc. Many challenges and difficulties are also discussed in energy exploitation and utilization related to ocean robots. Finally, the prospect for the future development of related technologies is proposed in this paper.
