Abstract

An indoor charger equipment is applied to an indoor space with an artificial light source and an electric appliance. The indoor charger equipment includes a photoelectric conversion module and an electric energy storage device. The photoelectric conversion module includes a plurality of perovskite-based photovoltaic cells stacked into a multilayer structure. The multilayer structure is placed in the indoor space facing the artificial light source, so that the light sequentially penetrating these perovskite-based photovoltaic cells is absorbed and photoelectrically converted into electrical energy. The electric energy storage device is electrically connected with the photoelectric conversion module for storing the electric energy. The electric appliance is electrically connected with the electric energy storage device to receive the electric energy for operation. Therefore, the light energy that was wasted in places where silicon-based solar cells could not work can be effectively converted into electrical energy and recycled for reuse.

Abstract

A light emitting element, used behind a display, comprises LED chips emitting blue light and separated red and green phosphor layers on the LED chip, the layers receiving the emitted blue light and respectively converting the same into precise colors for the display. A portion of the light directly from the LED chip is also combined with the converted light and passed on as lighting for the display. Partial absorption of green light by the red phosphor and red light by the green phosphor, occurring when the red and green phosphor layers are overlapped, is avoided. Light conversion efficiency of the green and red phosphor layers is thereby improved. A light emitting assembly, a display device, and a method for making the light emitting assembly are also disclosed.

Abstract

A very small piezoelectric sensor capable of being mass produced includes a core, a piezoelectric layer on a surface of the core; and a conductive layer on a surface of the piezoelectric layer away from the core. The core is flexible and threadlike, the core is a first electrode of the piezoelectric sensor, and the conductive layer is a second electrode of the piezoelectric sensor. An array of such sensors allows the “skin” of a robot for example to simulate the sensitivity of hair-covered human skin. A method for making the piezoelectric sensor and an electronic device using the piezoelectric sensor are also disclosed.
