The Interactive Computer Program to Fit I-V Curves of Solar Cells

ABSTRACT: Computer program has been developed to lit illuminated I-V curves of solar cells. The main effort has been put to achieve reliable fit rather then the optimum speed. A concept of a now weight factor modifying an object function has been introduced. i-V curves of the cells fabricated and measured in different laboratories were analysed. Results are compared with other concepts of the object functions. It is shown that the best fit is achieved with the exponential we fit which gives the best linearization of the I-V curves in respect to the parameters being calculated.
