Defects in poly-Silicon and amorphous Silicon solar cells

Authors

The paper introduces the issue of the typical

defects present in PV-cell. Typical defects are introduced for

two different technologies of photovoltaic devices: the

multicrystal Silicon and the amorphous Silicon one. The defects

have been implemented on a tridimensional model of a well

operating cell implemented in Comsol Multiphysics

environment. The aim of the paper is to simulate the behaviour

of possible defect as they are pointed out by means of

thermography. Defects have been modelled as they are

described in literature and implemented into the model of

photovoltaic cells. A multiphysical analysis, needed to study the

effects of the defects on the cell behaviour, has been conducted

using utilities available in Comsol environment.
