Abstract

This paper presents the basic principles of solar cells/ panels and explores its different models, such as single and double diode models. The main purpose of this research is to confirm that the principle of multi-junction solar cell (MJSC) operation to improve the conversion efficiency. To perform this simulation, single and double diode models have been developed. The process was ultimately utilized to find the influence of irradiance and temperature in electricity generation. In addition, the ideality factor and the impact of resistance on conversion efficiency also have been investigated. Maximum power point tracking (MPPT) method was used and optimized to improve the MJSCs performance for conversion efficiency improvement. The I-V and P-V curves show that double diode model produced more accurate results than the single diode model. The MJSCs expand the band gap and reduce the temperature influence in simulation to increase the energy conversion efficiency using the optimized MPPT method.
