Indium Sulfide. The indium sulfide (In2S3) possesses a high temperature modification which has a defect spinel structure, and a low temperature modification which is a superstructure of the spinel structure (16, 18, 19, 21). Several MIn2S4 compounds have the spinel structure (17) and we observed the existence... 

Tris(dialkyldithiocarbamato)indium(Iip compounds In[S2CNR2]3 exist as discrete molecules with distorted octahedral indium sites. The related In[S2COEt]3 has a similar structure. The five-coordinate ClIn[S2CN(i-Pr)2]3 displays square-pyramidal geometry.Compounds such as In[S2CO-i-Pr]3 serve as precursors for indium sulfide films. 

Thioacetamide, which is well established for the precipitation of ZnS in solutions, can be also used [68] in which case the films have been deposited from acidic solutions. The addition of urea has a beneficial effect on the adherence [68], Some attempts have been made to deposit ZnS by using thiosulfate-based solutions [16], As compared to CdS and PbS it appears that the deposition of ZnS films is not yet optimized and in addition presents some differences in the growth mechanism. This is illustrated by the lower activation energy values ( 20 kJ.rnol" ) which has been determined in the ammonia-thiourea-hydrazine process, which is more likely characteristic of a diffusion limited growth [69]. The deposition of indium sulfide has been also reported in acidic solutions using TA [52], along with a detailed study of the influence of the deposition conditions on the structural and optical properties of the films. 

Indium sulfide (In2S3) is an important material for PV applications [239, 240]. Due to its band value (2-2.8eV), it can replace Cd8 in CIG8-based solar cells to avoid toxic Cd and realize more environmentally friendly PV technology. Results for the development of Cd-free buffer layers for CIG8 thin-film solar cells from different laboratories have shown that 383, with optimal physical properties, can meet the requirements for use as window material or buffer layer for these PV structures [248],... 

Tetragonal Sodium sulfide and indium adopt the tetragonal system. This is similar to the cubic structure, but it s stretched along one of the axes, so now not all of the sides are of equal length therefore, a = b c and a=P = Y = 90°.
