Abstract

We have started a new research project on a hybrid power generation system consisting of piezoelectric, thermoelectric and solar cell modules. In the first step, we have focused on the antireflection coating based on zinc oxide (ZnO) and metal nanolayers incorporated in solar cells. In layered structure containing ZnO and metal nanoscale layers, we have presented the possibility of increasing wave transmission in the visible region by adding the top and bottom cap layers. The enhancement of optical transmission is very important in improving the performance of sensor protections, solar cells, UV protective films and transparent conductive display panels electrode. It is found that, the structure containing both the top and bottom cap layers (S3) yields larger transmittance than the structures S1 without any cap or S2 just with one cap layer. The maximum transmittance in the visible range can be increased from 33% to 67%. In addition, for the TE mode (TM mode), the maximum value of transmission in the S1 and S2 structures occurs at angles close to normal incidence while in the S3 multilayer it happens around 1 radian, that is, the behavior of the TE mode is the opposite of the TM mode. Also, when the incident angle varies, the band edges experience a blue shift. The amount of TE shift is more pronounced than TM one. Moreover, the metal with higher plasma frequency will move the band gap edges to the higher frequencies.
基于ZnO和Ag薄膜的窗口层作为混合节能系统的一部分应用于太阳能电池
我们已经开始了一个由压电、热电和太阳能电池组件组成的混合发电系统的新研究项目。在第一步,我们专注于基于氧化锌(ZnO)和金属纳米层的抗反射涂层,并将其结合到太阳能电池中。在含有ZnO和金属纳米层的层状结构中,我们提出了通过增加顶部和底部帽层来增加可见光区波透射的可能性。光传输能力的增强对传感器保护、太阳能电池、紫外线保护膜和透明导电显示板电极的性能的提高具有重要意义。结果表明,包含顶帽层和底帽层的结构(S3)比没有帽层的结构S1和只有一帽层的结构S2的透光率更高。可见光范围内的最大透过率可由33%提高到67%。另外,对于TE模式(TM模式),S1和S2结构的透射最大值发生在接近法入射角处,而S3多层结构的透射最大值发生在1弧度左右,即TE模式的行为与TM模式相反。此外,当入射角变化时,带边缘经历蓝移。TE偏移量比TM偏移量更明显。此外,等离子体频率较高的金属会使带隙边缘向更高的频率移动。
