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.
It may seem that the cost of quartz countertops is too much, but in reality, it all depends on the surface on which you are installing them. Moreover, the quartzâs high level of durability ensures that the countertop will be with you for a long time.t may seem that the cost of quartz countertops is too much, but in reality, it all depends on the surface on which you are installing them.
