Jaguar electric boat breaks the world’s speed record with its electric boat. As we know Jaguar is famous for its luxury vehicle brand of Jaguar Land Rover, and not only luxury vehicles but also electric cars, and what about electric boats? It really sounds fantastic, they released not only electric boat but also electric boat brakes the speed record.
Engineers from South Korean university Hanyang developed thin solar photocells, which can be pasted on any curvilinear surface, previously having soaked them in water. Thin layer photocells are created on the basis of the amorphous silicon sated with hydrogen. Their structure and way of production practically don’t differ from this kind of solar panels. The innovation brought by authors, is that between a basis, the silicon plate, and a thin photoactive layer brings a metal layer. This fact allows easily to separate a thin photocell from a silicon basis, which can be used repeatedly. The process reminds gluing of transfers -a soaking in water with the subsequent transfer on the necessary surface. Authors showed that new thin photocells can be put on such materials as paper, plastic, a windowpane or a back wall of the mobile phone. Thus, initial efficiency of electro generation, which makes about 7,5 percent doesn’t decrease. The panels with quantum points have two nuances: on the one hand, panels have to be rather thin, that light of the Sun could pass through them, and on the other hand, they shouldn’t be too thin, that the delay of light was effective. To adjust ideal composition and materials – rather complex challenge, but it became possible with zinc oxide in their structure. From zinc oxide experts created nano wires, this provided interaction with light photocells. According to the scientists the production of light-weight flexible solar energy cell overcomes the limitations of traditional methods, while maintaining performance. The scientists believed, that the new cells could broaden the spectrum of solar energy cells. Earlier, other group of engineers already showed the super thin and flexible photocells created on an organic substrate. Their efficiency was twice lower. Also, the recently scientific developed flexible and transparent batteries, which can serve for energy accumulation from similar flexible photocells.
