Microwave‐Assisted Solvothermal Synthesis of Copper Indium Diselenide Powders

Abstract

Copper indium diselenide (CuInSe 2 ) powders were successfully synthesized using the microwave-assisted solvothermal process at 2001C within a short time. The reaction time for preparing singlephased CuInSe 2 was significantly shortened with the developed microwave treatment. The microwave field enhanced the mobility of the reactants, thereby resulting in an accelerated reaction rate. CuSe was the major intermediate product during these reactions and the CuInSe 2 phase was gradually formed as the reaction temperature and time were increased. The prepared powders exhibited plate-like and spherical shapes, and the fraction of plate was increased with increasing reaction time. The solvothermal route combined with the microwave heating system was found to significantly promote the formation of plate-like particles.

“…Thin film solar cells have attracted substantial attention globally because of increasing demand for energy . Among various absorber materials used in thin film solar cells, chalcopyrite Cu(In,Ga)Se 2 is an effective candidate because of its direct band gap and high absorption coefficient .…”

Synthesis and Characterization of Silver Indium Diselenide Thin Films Prepared via the Sol‐Gel Assisted Process

“…Thin‐film solar cells have been rapidly developed because of their low cost and low material consumption advantages . As a result of the high optical absorption and direct band gap, the ternary I–III–IV 2 compounds with the chalcopyrite structure are regarded as promising materials for thin‐film solar cell applications . AgInSe 2 , one of the ternary compounds, have the ability to be n‐type or p‐type semiconductors.…”
