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.
Prices for quartz countertops range from about $30 to $170 per square foot for the materials and professional installation. When you get quartz countertop estimates, where they fall in that price spectrum will be decided by several factors that we discuss here.
