Electrical and optical characterization of Na: CuInS2 thin films grown by spray pyrolysis

“…To date, CdTe and Cu (In, Ga) Se 2 absorbers are the more promising semiconducting compounds since better efficiencies have been reached using these materials (19% for CIGS and 16% for CdTe [1]). CuInS 2 is a promising absorber material for thin film solar cells due to its high absorption coefficient (å10 4 cm À 1 ) and its optical band gap, which ranges from 1.3 to 1.5 eV for CuInS 2 polycrystalline thin films [2]. These values are close to the optimal value for the solar cell absorber materials.…”

Growth and characterization of chalcopyrite CuInSe2 nanoparticles

“…The compound semiconductors, particularly CuInX 2 (X = S, Se) have several desirable features as absorbers in thin film solar cells due to their direct band gap (*1.05 eV), high absorption coefficient and good radiation stability [1][2][3][4], making them a promising material for solar cell applications. There are several diversified techniques to fabricate CuInSe 2 (CIS) such as evaporation [5][6][7], sputtering [8][9][10], spray pyrolysis [11,12], chemical method etc. [13][14][15][16][17].…”
