Presented at: 20th European Photovoltaic Solar Energy Conference and Exhibition, Barcelona, Spain, 6-10 juni 2005.


Given the current shortage of off-spec p-type silicon from the microelectronics industry to feed the rapidly growing PV industry, research is being conducted to explore other types of silicon feedstock to produce solar cells and modules. In particular, within the EU funded NESSI project a technology is under development to purify n-type Si feedstock from highly-doped off-spec n-type silicon and produce thin n-type multicrystalline wafers.

A technology to process solar cell over these substrates and to interconnect them with a low-temperature process has been developed. Module prototypes have been built and their performance evaluated.
