Chemical liquid deposition of CuInSe2 and CuIn(S,Se)2 films for solar cells

Ternary and quaternary metal chalcogenide nanocrystals: synthesis, properties and applications

“…It efficiently removes the organic ligand layer and improves the overall conductivity of the lm. Sintering of the ternary and quaternary nanocrystals is widely used in the fabrication of allinorganic nanocrystal based solar cells 31,67,110,[158][159][160][161][162][163][164][165][166]173,174 and in thermoelectric devices. 127,129,167 The main disadvantages of sintering are the high energetic cost and the incompatibility with exible substrates.…”

Synthesis of CIS (CuInSe2) Based Materials for Solar Applications

“…It is known that processes based on vacuum technology have some disadvantages such as high energy consumption, high processing temperature, necessity of ultrapure materials, and limitation in total area of films [6]. Other types of methods of synthesis involve methods such as electrodeposition [7], chemical deposition [8,9], hydrothermal process [10], and solvothermal process [11,12]. It appears from earlier work that the solvothermal method is the simplest low-cost process for manufacturing and suitable for PV industry.…”

CuIn(S,Se)2 thin films prepared from a novel thioacetic acid-based solution and their photovoltaic application

“…19 In contrast, pure precursor solution methods generally provide a high yield, are simple in the scale-up process, and have precise stoichiometry control at the molecular scale. 20,21 The hydrazine-based solution method has been successfully used to fabricate high-efficiency thin film solar cells because of the excellent ability of the solution to dissolve metal chalcogenides such as Cu 2 S and In 2 S 3 , 9,[22][23][24] Nevertheless, the highly toxic and explosive hydrazine is a barrier for the mass production of those films. It is essential to develop a facile, green and low-cost method to prepare an air-stable precursor containing Cu, In and S (and/or Se), which is an important direction for the current non-vacuum CISSe-based solar cells.…”
