Article
Silver antimony sulfide selenide (AgSbS1.3Se0.7) thin film forms from silver antimony sulfide (AgSbS2, 700 nm) and amorphous selenium (Se, 300 nm), both obtained via chemical deposition, heated in contact at 180 oC for 30 min in an argon ambient. The fcc‐structure of AgSbS2 (cuboargyrite) is maintained in AgSbS1.3Se0.7. The optical bandgap of 1.8 e...

Polycrystalline thin films of AgSbS2 of thickness 140 nm and crystalline structure matching that of the mineral cuboargyrite (a = 0.5652 nm) are obtained by heating chemically deposited thin films at 150–320 °C. These films are deposited at 40 °C from a solution mixture containing antimony-thiosulfate complex and Ag-nitrate at a mole-fraction Ag/(A...

Photo-crystallization is a rapid thermal processing technique which uses concentrated sunlight toward the absorber film by a glass lens of 8.5 cm in diameter. This process minimizes loss of volatile components (S, Se) when heated conventionally. The solar cell has open circuit voltage 0.45 V, short circuit current 9.4mA/cm2 and conversion efficienc...

Full-text available
Thin films of antimony sulfide (Sb2S3) were prepared with different silver-ion content in a chemical deposition bath, and silver antimony sulfide (AgSbS2) was produced through the addition of higher concentrations of silver-ions in the bath. The chemical deposition solution mixture contained antimony trichloride (SbCl3) and sodium thiosulfate (Na2S...
Thesis
In the present work novel materials and solar cells based in silver antimony chalcogenides are developed by all-chemical deposition. A chemical formulation for the deposition of amorphous Ag-Sb-S thin films is presented. When this film is annealed, the formation of AgSbS2 is seen, which presents Eg of 1.79 eV, σlight = 1.6 × 10−5 Ω−1cm−1 with cubic...

Polycrystalline cubic-AgSbS2 (a = 0.5652 nm) is obtained by heating amorphous thin film of Ag-Sb-S, deposited at 10 ºC from a solution mixture of antimony salt, thiosulfate and silver nitrate. A film of thickness 700 nm is obtained via sequential deposition. The amorphous Ag-Sb-S film has an optical band gap (Eg) of 2.03 eV and crystalline, 1.79 eV...
Article
Thin films of AgSbS2 (150 nm) are prepared (75 min at 40 °C) via chemical deposition using a solution mixture containing SbCl3, Na2S2O3 and AgNO3. As-deposited films are amorphous. When they are heated in nitrogen at 180-320 °C, crystalline cubic-AgSbS2 films are formed. They show an optical band gap 1.89 eV and photoconductivity 1.8x10-5 Ω-1cm-1....
Conference Paper
Full-text available
Abundance of antimony in the earth’s upper crust is near 0.2 ppm, with an annual production nearly two hundred thousand tons, and 99.65% ingot price below US$15/kg, thus making antimony-based semiconductor compounds attractive for solar cells. The optical band gap (Eg) 1.5-1.8 eV of antimony sulfide qualifies it as a solar cell absorber, particular...
Article
We report on PbSe thin films serving as an absorber in solar cell structures, . The cells are prepared by sequential chemical deposition of the films on a commercial coated sheet glass. These cells show of 690 mV and of and a conversion efficiency of 0.69% under sunlight. Two distinct routes are taken to deposit PbSe thin films of 100–250...
