Abstract – The generation of a small signal dynamic model of a
solar cell was investigated. As a starting structure the usual one
diode large signal dynamic model was used with known parameter
values. A simple parallel linear RC circuit was used to represent
the model while the element values were put to be functions
of the illumination here represented by the photo-current. The
element value versus photocurrent dependences were captured by
artificial neural networks one per element. Verification of the
model was performed by comparisons of the responses of the
original nonlinear dynamic model and the linear RC model to a
chirp signal of small amplitude.
