Carbon-based organic photovoltaic cells, which use organic polymers or small molecules as semiconductors, are significantly thinner and cheaper than their inorganic silicon-based counterparts. Unfortunately, they are also much less efficient at converting sunlight into electricity. That could be on its way to changing, however, as an international team of researchers have reportedly boosted the efficiency of organic photovoltaic cells by 20 percent ... with some help from gold nanoparticles.
The MH-2 is a telepresence robot like no other we have seen, and believe us, we’ve seen our share of weird robots. This tiny humanoid figure is always there for you, perching on your shoulder, ready to be remotely inhabited by your friends. Conceived by the researchers at Yamagata University in Japan, MH-2 is designed to imitate human behavior accurately enough for you to feel like your friend is actually there with you.
