Tin sulfide (SnS) is a semiconductor with direct optical band gap of 1.3 eV and absorption coefficient above 10 4 cm â1 for photon energies above 1.3 eV. It is a p-type semiconductor whose electrical properties can be tailored by doping and structural modification and has emerged as one of the simple, non-toxic and affordable material for thin films solar cells since a decade.
Quartz: Letâs talk installation costs so that we can get a realistic, final price. Quartz has historically been more expensive than granite, but times have changed, technology has improved and now the discussion is not so cut-and-dry. Quartz generally runs from about $65-$100 per square foot installed. So your average quartz countertop of, say, 40 square feet will run from $2,600-$4,000.
The Cost of Granite vs. Quartz Countertops Itâs really about a toss-up in this category. The cost of quartz ranges from $80-$140 per square foot installed and granite starts at about $80 and can go to $175 or slightly higher for high-end material.
