Abstract:
A wireless transceiver apparatus is provided. The wireless transceiver apparatus includes a signal transmitting circuit, a circuit unit, and a signal receiving circuit. The signal transmitting circuit includes a first output port and is utilized for outputting a first transmission signal via the first output port in a transmission mode. The circuit unit is coupled to the first output port of the signal transmitting circuit. The signal receiving circuit includes a first receiving port and is utilized for receiving a first wireless communication signal via the first receiving port in a reception mode. The first output port is coupled to the first receiving port at a first node. The circuit unit forms a frequency resonance mode to increase an impedance value of the signal transmitting circuit seen by a signal at the first node.
Abstract:
Disclosed is a solar cell including a first base layer, a second base layer on the first base layer, and an emitter layer on the second base layer. Furthermore, a window layer may be disposed on the emitter, and/or a back surface field (BSF) layer may be disposed under the first base layer.
Abstract:
The present application relates to an opto-electronic device. The opto-electronic device includes an n-cladding layer, a p-cladding layer and a multi-quantum well structure. The multi-quantum well structure is located between the p-cladding layer and the n-cladding layer, and includes a plurality of barrier layers, a plurality of well layers and a barrier tuning layer. The barrier tuning layer is made by doping the barrier layer adjacent to the p-cladding layer with an impurity therein for changing an energy barrier thereof to improve the light extraction efficiency of the opto-electronic device.
