Multiphase CuInSe2 (CISe) nanoparticles including the secondary CuSe phase are synthesized by a polyol-based, microwave-assisted solvothermal method. It is demonstrated that the reaction chemistry involving formation of the CISe phase is adjusted depending on the heretofore unrecognized chemical nature of polyol solvent, allowing for formation of secondary CuSe phase-incorporated multiphase CISe nanoparticles. The critical role of CuSe phase in generating the pore-free, dense CISe absorber layer for a high-performance thin-film photovoltaic device is investigated through the comparative study on CISe absorber layers derived from both multiphase and single-phase CISe nanoparticles.
