ABSTRACT
The photovoltaic market currently consists mainly of Si, CdTe, CIGS,
and III-V compound-based solar panels. There are some issues,
especially on variations in performancemeasurements, stability, and
lifetime. Some of these variations and behaviours, especially in thin-
film solar cells, are not well understood at present. This chapter,
therefore, addresses this subject. The experimental attempts made
on this front, with possible explanations to the observed results
and some solutions to reduce these undesirable behaviours, are
presented in this chapter.
