R&D is especially important for new cell technologies to enter the
manufacturing sector and markets. There are a number of PV cell
technologies, each of which offers unique characteristics. New cell
technologies evolve through R&D but also require manufacturing experience
to become commercial. Because PV cell manufacturing requires large
investments, market and manufacturing volume is very important.

The MUSIC FM project concluded that up-scaling the manufacturing plant to
500 MW would result in module costs below € 1 1995 per W for multicrystalline
silicon. In theory, manufacturing costs for different thin-film
technologies would be around € 0.7 1995 per W at a scale of 60 MW. A recent
study by Arthur D. Little indicated that cost reductions close to 50% are
possible for most technologies in the period from 2000 to 2010, bringing
manufacturing costs down to USD 0.95 to 1.40 per W. Major contributions
come from:
● up-scaling from 10 MW to 100 MW, allowing cost reductions due
to volume purchase, balanced line, larger equipment and higher
throughput;
