Abstract
An increasing energy demand and growing environmental concerns regarding the use of fossil
fuels in South Africa has led to the challenge to explore cheap, alternative sources of energy.
The generation of electricity from Photovoltaic (PV) devices such as solar cells is currently
seen as a viable alternative source of clean energy. As such, crystalline, amorphous and
nanocrystalline silicon thin films are expected to play increasingly important roles as
economically viable materials for PV development. Despite the growing interest shown in these
materials, challenges such as the partial understanding of standardized measurement protocols,
and the relationship between the structure and optoelectronic properties still need to be
overcome.
