Concrete Optimization and Modeling of Organic Tandem Solar Cells Using Series Resistance, Temperature and Optical-Bandgap

Abstract

A comparative study of two methods for extracting solar cell parameters of single and two-diode lumpedcircuit model is presented. These parameters are usually the saturation current, the series resistance, the ideality factor, the shunt resistance and the photocurrent. It is found that the influence of the distributed series resistance on electrical characteristics can be described numerically by the application of the two models to Tandem organic solar cells. A description of the efficiency fill factor open circuit voltage and sort circuit current on the devices are marked with series resistance, optical band gap and atemperature .This approach allows one to obtain a set of parameters which is reasonable and representative of the physical system.
