Colloidal AgSbSe2 nanocrystals: surface analysis, electronic doping and processing into thermoelectric nanomaterials

“…15 However, an apparent optical bandgap of 0.6-1.1 eV 2, [15][16][17][18] and a high optical absorption coefficient (10 4 cm À1 ) have also motivated the use of AgSbSe 2 for photovoltaic applications. 2,17,[19][20][21] The AgSbSe 2 band structure is characterized by a multi-peak valence band maximum, which potentially results in a high effective mass for holes and thus a high Seebeck coefficient. In addition, AgSbSe 2 features a strong anharmonic bonding arrangement associated with the Sb 5s 2 lone pair, which translates into strong phonon-phonon interactions that reduce the lattice thermal conductivity to values close to the amorphous limit.…”

AgSb(SxSe1‐x)2 thin films by rapid thermal processing of Sb2S3‐Ag‐Se thin films for photovoltaic applications

“…AgSbSe 2 and its alloys stand out to be promising candidates for solar cell applications, due to their optical absorption coefficient of 10 4 cm -1 with a band gap of 0.9-1.1 eV [2,3]. Photovoltaic structures using AgSbSe 2 absorber thin films prepared by heating multilayers of Sb 2 S 3 /Ag 2 Se in contact with a chemically deposited Se thin film and CdS window layer showed promising results [4]. Our group have reported the preparation of AgSb(S x Se 1-x ) 2 thin films by heating layered structure of glass/Sb 2 S 3 /Ag after dipping in sodium selenosulfate solution [5].…”

A comparative study of the physical properties of Sb2S3 thin films treated with N2 AC plasma and thermal annealing in N2

“…Antimony sulfide (Sb 2 S 3 ) is a semiconductor compound that belongs to the groups V-VI, and due to its nature it can be used in optoelectronic devices, thus becoming of technological importance [1][2][3]. Recently, this material has been used in solar energy storage cells [4], and photovoltaic devices [5][6][7][8][9]. In addition, chemically deposited Sb 2 S 3 thin films have been used in the preparation of photovoltaic materials such as CuSbS 2 [5] and AgSbSe 2 [7,10].…”
