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.
A slab of granite is usually priced starting at $60 a square foot but the prices rise quickly from that point on. For quartz countertops, youâll generally be paying anywhere from $67 up to $95 per square foot.For a 28 ft.Â² counter made of quartz youâll have to budget for approximately $2200 â $3100.Here are some more details to help you get a closer estimate.
