Graphene-based nanomaterials have many promising applications in energy-related areas. In particular, there are four major energy-related areas where graphene will have an impact: solar cells, supercapacitors, lithium-ion batteries, and catalysis for fuel cells
The extremely high electron mobility of graphene – under ideal conditions electrons move through it with roughly 100 times the mobility they have in silicon – combined with its superior strength and the fact that it is nearly transparent (2.3 % of light is absorbed; 97.7 % transmitted), make it an ideal candidate for photovoltaic applications. It could be a promising replacement material for indium tin oxide (ITO), the current standard material for transparent electrodes used for electrodes in LCD displays, solar cells, iPad and smart-phone touch screens, and organic light-emitting diode (OLED) displays for televisions and computer monitors.

New nano-material could boost solar panel efficiency as high as 80% . Conventional solar cells based on photovoltaic technology have come a long way in recent years, but they’re still missing a big chunk of
the electromagnetic spectrum. The silicon semiconductors in a solar cell are geared toward taking infrared light and converting it directly to electricity. Meanwhile, the visible spectrum is lost as heat and longer wavelengths pass through unexploited. A new nano-material being developed by a group of researchers spread across the country could act as a “thermal emitter,” making solar power significantly more efficient by scooping up more of that wasted energy.

# Brunton Solaris Foldable Solar Power Array

Brunton has made a great product here. I use three of these linked together to charge my teardrop campers battery. When i dont need them, they fit easily inside a cabinet. When needed, i bungee cord them usually to a picnik table. You will need a solar controller. I use the

Buy from amazon

Morningstar model and it works great. You do notice usually 18 volts leaving the panels, but the controller will take care of that for you. I have camped for 3 days...watched a lot of TV, used the ceiling fan, lights, and water pump regularly with no worries of running out of power. Another plus of not mounting traditional panels to your trailer is you can park in the shade, and place your panels in the sun. Oh dont forget a longer cord!
