具有电压相关载流子收集的太阳电池中的广义互易关系：在p-i-n结器件中的应用
Generalized Reciprocity Relations in Solar Cells with Voltage-Dependent Carrier Collection: Application to p-i-n Junction Devices
摘要：
两个互易定理对于太阳能电池操作的基本理解和器件评估的应用是重要的：（1）连接暗载流子注入与短路光生载流子收集的载流子传输互易性和（2）连接电致发光与短路时的光伏量子效率的光电互易性。然而，这些定理在诸如p-i-n结太阳能电池的具有厚耗尽区的器件中失效。通过适当的线性化的载流子输运方程在这样的设备中，我们报告说，暗载流子注入有关的光生载流子收集效率在工作电压，而不是在短路的建议，在原来的定理。这导致了连接电致发光与电压依赖的量子效率的光电互易关系的一般形式，提供了p-i-n结器件的光电特性的正确解释。我们还讨论了开路电压和外发光效率之间的关系的有效性。定量研究了光照强度和器件参数对互易定理有效性的影响。
英文摘要：
Two reciprocity theorems are important for fundamental understanding of the solar cell operation and applications to device evaluation: (1) the carrier-transport reciprocity connecting the dark-carrier injection with the short-circuit photocarrier collection and (2) the optoelectronic reciprocity connecting the electroluminescence with the photovoltaic quantum efficiency at short circuit. These theorems, however, fail in devices with thick depletion regions such as p-i-n junction solar cells. By properly linearizing the carrier-transport equation in such devices, we report that the dark-carrier injection is related to the photocarrier collection efficiency at the operating voltage, not at short circuit as suggested in the original theorem. This leads to the general form of the optoelectronic reciprocity relation connecting the electroluminescence with the voltage-dependent quantum efficiency, providing a correct interpretation of the optoelectronic properties of p-i-n junction devices. We also discuss the validity of the well-known relation between the open-circuit voltage and the external luminescence efficiency. The impact of illumination intensity and device parameters on the validity of the reciprocity theorems is quantitatively investigated.
