Paper Abstract

Optical wireless transmission system using a solar cell can receive energy and information simultaneously with single link. Optical spectrum of transmitter is the one of factors in wireless energy and data hybrid transmission system, and optical spectrum effects should be researched. Firstly, the energy and data hybrid transmission system are designed and simulated based on lambert model and equivalent circuit of solar cell. Secondly, a hybrid transmission indoor experimental system is established using a monocrystalline silicon solar cell as a receiver. The frequency response of the solar cell is measured with different date rates and wavelengths. Additionally, the output signal’s amplitude and conversion efficiency of receiver with different wavelengths of transmitters (470nm and 850nm) are observed and measured in the process of energy transmission. What is more, 100 kHz output waveform of the receiver in the process of data transmission is researched and discussed in different intensities and wavelengths. The experimental results show that hybrid transmission of data and energy can be achieved in our indoor system. The energy transmission efficiency and amplitude of the receiver signal with 850 nm LED transmitter is better than those of 470 nm LED transmitter (2.1 times and 1.39 times, relatively) in energy transmission process. Compared to the performance using a 470 nm light source in data transmission process, the waveform contrast of 850nm light source band is better.
