【摘要】：激光诱发硅太阳能电池产生载流子,由于少数载流子的复合而发射红外辐射.基于一维载流子传输方程,建立了调制激光诱发PN结少数载流子密度模型,利用该模型仿真分析了载流子寿命、扩散率、表面复合率及光电压对辐射复合产生红外辐射信号的影响.利用InGaAs红外探测器(0.9~1.7μm)记录激光诱发载流子辐射复合的红外辐射信号,用数字锁相放大器提取了幅值与相位.通过频率扫描试验获得了多晶硅太阳能电池载流子传输参数.
[Abstract]:Laser induced silicon solar cells produce carriers and emit infrared radiation due to the recombination of a few carriers.Based on the one-dimensional carrier transport equation, a minority carrier density model of modulated laser-induced PN junction is established. The carrier lifetime and diffusivity are simulated and analyzed by using the model.The influence of surface recombination rate and photovoltage on infrared radiation signal produced by radiation recombination.The laser induced carrier radiation composite infrared radiation signal was recorded by using InGaAs infrared detector (0.9 渭 m), and the amplitude and phase were extracted by digital phase-locked amplifier.Carrier transport parameters of polysilicon solar cells were obtained by frequency scanning test.
