BISTABLE PHOTONIC CRYSTAL WITHOUT EXTERNAL POWER CONSUMPTIONTech for Transfer TTO 18-12-2015 The present invention provides the way to create a photonic crystal with fast response time and wide tunable range of wavelength, and meanwhile, remain at a stable state without external power consumption. The photonic crystal has a plurality of voids and each surface of void has an hydrophobic film. When the photonic crystal is immersed in a predetermined liquid, the crystal has two stable states. The first stable state is to fill the plurality of voids with the predetermined liquid, and the second stable state is to exclude the liquid from the plurality of voids. Owing to the energy barrier between the first and second stable states, the photonic crystal can remain at either of the two states without external power consumption.

OPTICAL FIBER 3D SOLAR CELLSTech for Transfer TTO 19-12-2015 In this invention, a dye-sensitized solar cell for harvesting solar energy is integrated with a piezoelectric nanogenerator for harvesting ultrasonic wave energy. The two energy harvesting approaches can work simultaneously or individually and can be integrated in parallel or in series for increasing the output current, voltage or power, respectively. The solar cell employs an optical fiber and semiconductor nanowires grown around the fiber. The fiber can transmit light, while the nanowires increase the surface area of light exposure. Light propagates through the fiber until it enters a nanowire where it reaches a photovoltaic element. Light in the fiber cannot escape until it interacts with a photovoltaic element, thereby increasing solar conversion efficiency. Fiber Optics Photovoltaics Tell me more |
