本研究係採用一種無線光通訊與能量傳輸(Optical Wireless Information and Power Transfer, OWIPT)的架構，分別使用發光二極體(Light Emitting Diode, LED)與多晶矽的太陽光電板(Photovoltaic Panel, PV Panel)作為發送端與接收端。
實驗架構中，我們分別使用TO-22封裝及OSRAM公司所生產的高功率LED作為發射光源，並使用函數波產生器來加入類比信號，使具有攜帶能量及信號的光經過空氣或水之後，被PV Panel 接收後，再透過通訊與能量收集 (Communication and Energy Harvesting, CEH ) 電路，將能量與信號進行分離。在CEH 電路中，我們分別使用直流電流表及示波器(Oscilloscope, OSC)觀察二種LED分別使用紅、綠、藍、白光作為發射光源時，所產生電流的大小及訊號的傳送情形。
實驗結果發現，在通信傳輸中，PV Panel 本身的頻率響應較低，限制了可以被接收的頻率大小，因此對攜帶中、高頻率信號的光之響應較低，另外在能量傳輸中，白光的光電轉換效率較好。

This research adopts a framework of Optical Wireless Information and Power Transfer (OWIPT), which uses Light Emitting Diode (LED) and polycrystalline silicon photovoltaic panel (PV Panel) as the transmitter and receiver, respectively.
In the experimental architecture, we use TO-22 package and high-power LED produced by OSRAM GmbH as the transmitting light source, respectively, and use the function generator to add the analog signal, so that the light with energy and signal passes through the air or water, after receiving the PV Panel, the communication and energy harvesting (CEH) circuit separates the energy and the signal. In the CEH circuit, we use a DC ammeter and an oscilloscope (OSC) to observe the magnitude and signal of the current generated when the two LEDs use red, green, blue, and white light as the transmitting light sources delivery situation.
The experimental results found that in communication transmission, the frequency response of the PV Panel itself is low, which limits the frequency that can be received. Therefore, the response to light carrying medium and high frequency signals is low, white light at the photoelectric conversion efficiency is better.
