Finally, in June GT Advanced Technologies announced a deal to supply its HiCz ingot pullers to Qatar Solar Energy, which the company will use to produce n-type wafers for production of high-efficiency PV at an integrated factory in Qatar.
GTM Research Analyst Shyam Mehta says that while there has been increased interest in n-type technologies lately, many companies have been pursuing high-efficiency PV designs based on n-type mono wafers for a number of years without significant success.
"People have been talking about the shift to n-type for a while, and we see it as part of a number of company's roadmaps," explains Mehta. "But in terms of actual market adoption so far, it's still pretty niche."
