A study of solar cells took place by using Lambert W function based diode model. All calculations were made through computer algebra, having the software Maple a special place. Current vs. Voltage graph corresponding to cells was obtained as a main result, so as diode’s parameters values such as the series, shunt resistances and its constant. Analytical results will be useful for cell manufacturing, either for home or industrial usage. As a future research line, Lambert W function utilization is suggested as a mean for multi-diode systems development.
The Lambert W function is applied via Maple to analyze the operation of the modern digital camera
sensors. The Lambert W function had been applied previously to understand the functioning of diodes
and solar cells. The parallelism between the physics of solar cells and digital camera sensors will be
exploited. Digital camera sensors use p-n photodiodes and such photodiodes can be studied using the
Lambert W function. At general, the bulk transformation of light into photocurrent is described by an
equivalent circuit which determines a dynamical equation to be solved using the Lambert W function.
Specifically, in a camera senor, the precise measurement of light intensity by filtering through color filters
is able to create a measurable photocurrent that is proportional to image point intensity; and such
photocurrent is given in terms of the Lambert W function. It is claimed that the drift between neighboring
photocells at long wavelengths affects the ability to resolve an image and such drift can be represented
effectively using the Lambert W function. Also is conjectured that the recombination of charge carries in
the digital sensors is connected to the notion of “noise” in photography and such “noise” could be
described by certain combinations of Lambert W functions. Finally, it is suggested that the notion of bias,
and varying the width of the depletion zone, has a relationship to the ISO “sped· of the camera sensor;
and such relationship could be described using Lambert W functions.
