摘要： A Cu2ZnSnS4-xSex (0≦x≦4) thin film solar cell is disclosed. The thin film solar cell includes a Cu2ZnSnS4-xSex (0≦x≦4) thin film as an absorber layer produced by forming a precursor film composed of Cu, Zn, Sn, and Se using an ionic liquid as a solvent through a constant current process and annealing the precursor film with sulfur. Also disclosed is a method for fabricating the thin film solar cell. The method uses a non-vacuum electrodeposition process that is appropriate for large-area mass production and is thus cost effective compared to a vacuum process. In addition, since the method uses an ionic liquid, the formation of by-products harmful to humans as a result of side reactions is suppressed. Furthermore, the method uses a one-step electrodeposition process, which enables the deposition of a maximum of four elements at one time, or a multi-step deposition process, and an annealing process.

摘要： The present disclosure relates to a novel polymer compound and a method for preparing the same. More particularly, the present disclosure relates to a novel conductive low band gap electron donor polymer compound having high photon absorptivity and improved hole mobility, a method for preparing the same and an organic photovoltaic cell containing the same. Since the conductive polymer compound as a low band gap electron donor exhibits high photon absorptivity and superior hole mobility, it can be usefully used as a material for an organic optoelectronic device such as an organic photodiode (OPD), an organic thin-film transistor (OTFT), an organic light-emitting diode (OLED), an organic photovoltaic cell, etc. as well as in the development of a n-type material.
