I recall that back in 2011 ..2012 the big push was in cost reduction then the market focus changed to efficiency.
The market was willing to pay a premium for higher efficiency cells vs spending $ make lower eff cells at a reduced cost.
That put a crimp in a lot of development work and caused a lot of reprioritization in R & D. 1000 Kg multi crystalline DSS furnaces shifted to 450 KG mono/ pseudo cast ingots and Cz mono gathered some steam. Multi crystalline cells have an eff below mono and n type mono can get to approx. 25 % +/-.
Good multi were up to 18% I believe. Not sure 15% panels will get a big welcome in the market place at least not in rooftop systems (industrial of residential) where area can be at a premium....in the dessert may the lower cost of lower eff panels will be acceptable.
