Abstract
Bioethanol is one of the alternative sources of oil resources which received attention with biodiesel. Many countries produce bioethanol from food sources such as corn and sugarcane, but it causes food-energy conflicts and farmland problem. So it needs to focus on new biomass which is sustainable, renewable, cost-effective and do not occurred any conflicts. Algae are one of the bioma

A Study on Properties of Cu/In ratio on the CuInS2 thin film
Abstract
CuInS2 thin films were synthesized by sulpurization of Cu/In Stacked elemental layer deposited onto glass Substrates by vacuum furance annealing at temperature 200[℃].
And structural and electrical properties were measured in order to certify optimumconditi
