Modelling shading on amorphous silicon single and double junction modules
conference contribution
posted on 2011-03-09, 14:55 authored by A. Johansson, Ralph Gottschalg, David InfieldThe effect of shading amorphous silicon mini-modules is investigated by means of measurements and simulation. Several devices are measured under varying degrees of
shading and the reverse bias behaviour is investigated, including the reverse breakdown voltage. A simulation using a modified single diode model for amorphous silicon is presented, in which the Bishop extension of the shunt
resistance is used to simulate the behaviour of shaded
devices. The differences between the effect of shading on
amorphous silicon and on crystalline silicon devices are
investigated based on measurements and simulations. It is
shown that the thin film cells do not develop hot spots in
the same manner as crystalline silicon devices; they
always break down at the interconnection to the adjacent
cell.
