Photon-enhanced thermionic emission (PETE) is a new type of solar cell. The existing papers on PETE research do not consider the structure of actual PETE devices; in practical PETE structure, the original incident light intensity is attenuated by the window layer and the buffer layer (include anode in reflection PETE devices). In this paper, according to two kinds of the common structure of PETE device, the influence of transmission and reflection of sunlight on the conversion efficiency of PETE device is analyzed. Using a light-trapping structure on the cathode of the PETE device is a valid method to reduce the reflection of the incident light. The calculation results show that the optical attenuation has a great influence on the actual photon flux received by the cathode effective layer. Under the condition of reasonable operation of the device, the efficiency of PETE can be improved by reducing the size of the material, improving the light transmittance of the buffer layer and window layer, and using the light-trapping structure.

考虑光衰减对实用结构光子增强热电子发射转换器的影响

光子增强热电子发射(PETE)是一种新型太阳能电池。现有关于PETE研究的论文没有考虑实际PETE装置的结构;在实际的 PETE 结构中,原始入射光强度被窗口层和缓冲层(包括反射 PETE 器件中的阳极)衰减。本文根据PETE器件的两种常见结构,分析了太阳光的透射和反射对PETE器件转换效率的影响。在 PETE 设备的阴极上使用光捕获结构是减少入射光反射的有效方法。计算结果表明,光衰减对阴极有效层接收到的实际光子通量有很大影响。在设备合理运行的情况下,
