Thin-film solar cells: Review of materials, technologies and commercial status

Abstract

The recent boom in the demand for photovoltaic modules has created a silicon supply shortage, providing an opportunity for thin-film photovoltaic modules to enter the market in significant quantities. Thin-films have the potential to revolutionise the present cost structure of photovoltaics by eliminating the use of the expensive silicon wafers that alone account for above 50% of total module manufacturing cost. The strengths and weaknesses of the contending thin-film photovoltaic technologies and the current state of commercial activity with each are briefly reviewed. © Springer Science+Business Media, LLC 2007.
