Cu(In,Ga)Se2 and CuInSe2 thin film solar cells have achieved high energy conversion efficiencies because of their tunable bandgaps and high absorption coefficients. For reducing the production cost,vacuum processes need to be substituted by non-vacuum ones such as solution- or nanoparticle-based processes. Among them, Cu-In alloy nanoparticle-based processes are favorable to precursor film formation and pore elimination during selenization.In this study, morphological aspects of Cu-In alloy nanoparitlce layers are investigated upon selenization in various conditions. The evolution of microstructure during thermal treatment will be discussedin association with intermediate crystalline phase transformation. |
