Abstract:
In a method for simulating fluid flow using Tsallis entropy and Rényi entropy, the method includes a space defining step, a state determining step, a flow effect generating step, and a state renewal step. In the space defining step, a simulation space having lattices is defined. In the state determining step, a space occupation state is determined by objects, a fluid state, and a probability distribution state of a particle with respect to a velocity of the particle, for nodes of the lattices of the simulation space. In the flow effect generating step, a flow effect for nodes of the lattices of the simulation space is generated by using a collision rule, as a probability distribution of a particle with respect to a velocity of the particle, which is obtained by satisfying a condition at which Tsallis divergence between the collision rule itself and a reference collision rule which is obtained under a given condition has an extremal value. In the state renewal step, a state of the simulation space is renewed, based on the flow effect generating step.

Abstract:
Disclosed is a method for producing a copper indium selenium (CIS) or copper indium gallium selenium (CIGS) thin-film light-absorbing layer. The method includes forming a coating layer of CIGS slurry, removing a solvent, a dispersant and a binder from the coating layer to form a powder coat layer, pressing the powder coat layer to improve its particle packing density, and heating the powder layer to form a dense thin film. The method uses a powder process as a non-vacuum process to produce a CIS or CIGS thin film in high yield at low cost. Further disclosed is a method for manufacturing a thin-film solar cell including the production method.
