Spheroidal Si solar battery

Development that aims at the cost reduction of the solar battery is interesting.  At this time, the main solar power generation system is polycrystal Si solar battery. The majority of the manufacturing cost is polycrystal Si of the raw material.
”Spheroidal Si solar battery” that uses minute spheroidal polycrystal Si is a technology that can greatly reduce the amount of use. The amount of the Si use is called 1/5. The expectation of the cost reduction is great.
I am paying attention to “Clean Vnture 21” company in Japan.
