Influence of feedstock on c-Si module cost
conference paper
This paper analyzes the impact of solar silicon feedstock alternatives on the wafer-based crystalline silicon photovoltaic (PV) module cost. As the impact of feedstock affects the whole manufacturing chain of a PV technology, its technological steps need to be defined. This is done with a number of roadmap scenarios that have been defined in the CrystalClear project. Advanced Basepower is defined as the reference technology, developed in a high throughput plant (300-500 MWp/a) which is built now with state-of-the-art technology, and ready to operate in 2011. Six more advanced technologies, two multicrystalline, two monocrystalline, one ribbon technology, and one wafer-equivalent technology are also defined. Regarding Advanced Basepower technology, the cost advantage of using low-cost feedstock (10߿Ưkg) instead of high-cost feedstock (30߿Ưkg) is lost if the cell efficiency is reduced, due to quality degradation, by an absolute 1.7%.
