Defect Structure and Photogenerated Carrier Loss Processes in Cu1 –x(In0.7Ga0.3)Se2 (0 ≤ x ≤ 0.30) Chalcopyrite Solid Solutions

Molecular modelling and synthesis of a new collector O-butyl S-(1-chloroethyl)carbonodithioate for copper sulfide ore and its flotation behavior

“…The lattice optimization results were shown in Table 2. Then, 2D periodic surface cells were created from the unit cells of chalcopyrite [13][14][15] and pyrite 16 at the cleavage plane (101)and (101), respectively. The optimized chalcopyrite surface slab was extended to a periodic super lattice of approximately 25 A Â 20 A with a certain vacuum thickness of 27 A.…”

Crystallographic and Luminescence Characteristics of the Cu2MgSnSe4 Quaternary Compound and Cu2 – xMgSnSe4 (0 < x ≤ 0.15) Copper-Deficient Solid Solutions

“…Further, Cu 2 -x MgSnSe 4 copper-deficient solid solutions can be of interest for the fabrication of the absorbing layer in thin-film solar cells because, by analogy with the CIGS [8] and CZTS [9] materials, copper deficiency should be expected to ensure required properties, including necessary p-type conductivity, and raise the electrical conductivity of the material.…”
