PROJECT TITLE :

An Explicit Multiexponential Model as an Alternative to Traditional Solar Cell Models With Series and Shunt Resistances

ABSTRACT:

Classical analyses of numerous conventional solar cell models are examined. They are unified through the separation of their linear and nonlinear components and the application of Thevenin's theorem to the linear terms. An express multiexponential model with series and shunt resistances is proposed as an alternate to conventional implicit multiexponential models commonly used to explain significant parallel conduction mechanisms in real solar cells. The proposed model is best suited than conventional models for repetitive simulation applications because of its inherently higher computational efficiency. Its specific nature is a terribly helpful feature for direct analytic differentiation and integration. The model's applicability has been assessed by parameter extraction and subsequent playback using synthetic I–V characteristics of a hypothetical solar cell at various illumination levels chosen purely for illustrative purposes.
