The photoelectrochemical properties of (Ag,Cu)GaSe2 (ACGSe) modified by deposition of CdS and CuGa3Se5 layers were investigated. The CdS and CuGa3Se5 layers formed p–n junctions with an appropriate band diagram on the surface of the electrode and they clearly increased the cathodic photocurrent and onset potential. The Pt, CdS, and CuGa3Se5 modified ACGSe (Pt/CdS/CuGa3Se5/ ACGSe) with an approp...
This study evaluates the effect of silver alloying, stoichiometry, and deposition temperature wide-gap (Ag,Cu)GaSe2 (ACGS) absorber films for solar cell applications. Devices using a standard CdS buffer exhibit strong anticorrelation between open-circuit voltage (VOC) short-circuit current density (JSC), with VOC decreasing JSC increasing toward stoichiometric composition. Increasing ACGS leads...
The light gray selenogallate CsGaSe2-mC64 was obtained by reaction of stoichiometric amounts of CsN3, GaSe, and Se at elevated temperatures. Its crystal structure was determined by single-crystal X-ray diffraction. The compound crystallizes in the monoclinic space group C2/c (No. 15) with a = 11.043(2) Å, b = 11.015(4) Å, c = 16.810(2) Å, β = 99.49(1) °, V = 2016.7(8) Å, and Z = 16 (powder data...
