Abstract
This research appraises comparative analysis between single diode and double diode model of photovoltaic (PV) solar cells to enhance the conversion efficiency of power engendering PV solar systems. Single diode model is simple and easy to implement, whereas double diode model has better accuracy which acquiesces for more precise forecast of PV systems performance. Exploration is done on the basis of simulation results and MATLAB tool is used to serve this purpose. Simulations are performed by varying distinct model parameters such as solar irradiance, temperature, value of parasitic resistances, ideality factor of diode and number of series and parallel connected solar cells used to assemble PV array. Conspicuous demonstration is executed to analyze effects of these specifications on the efficiency curve and power vs. voltage output characteristics of PV cell for specified models.

Summary
The globe gains an unbelievable supply of solar energy. The sun is an average star, a fusion reactor. Material property of semiconductor is the reason of photovoltaic phenomena, which enables consumption of distinct type of photons from sunlight and these photons have higher energy than the band-gap energy of the semiconductor [5] This leads to formation of a few free electron-hole pairs in the cell which are precisely proportional to input solar irradiance. This paper presents a comparison between single-diode model and double-diode model of photovoltaic (PV) module to determine cell accuracy for different changing parameters. Both models are implemented in MATLAB environment by adjusting model parameters with similar configurations
