Cu(In,Ga)Se₂ SOLAR CELLS

Growth and properties of single crystals of the ternary CuIn5Se8 compound

“…3 shows a plot of (a_n) 2 versus (_n). The continuous line is a least-squares fit to the data in the region where (a_n) 2 gap increases as the temperature decreases [1]. For the description of the dependence given, the empirical Bose-Einstein expression was used [18]:…”

“…The broad range of optical and electrical properties offered by A I B III C VI 2 compounds has led to their applications in light-emitting diodes, photovoltaic and nonlinear optical devices [1][2][3]. Solar cells made from polycrystalline Cu(In, Ga)Se 2 absorber layers have shown the best energy conversion efficiencies of all polycrystalline thin-film solar cells.…”

Surface Composition of CIS Compound Affected by Xe⁺ Irradiation

“…Among Cu-chalcopyrite semiconductors, the compound CuInSe 2 (CIS) is of great interest in photovoltaics as a result of acceptable energy gap width (1-2.4 eV), high optical absorption coefficient ((3−6) × 10 5 cm −1 ), high efficiency (20.3%) and radiation resistance [1][2][3][4][5]. These features give an opportunity to use CIS compound for production of inexpensive, operation stable and highperformance solar thin-film elements (STE).…”

Preparation and properties of In/p‐Cu(In1–xGax)(S1–ySey)2 surface‐barrier structures

“…It is known that a critical problem related to this process is the segregation of Ga towards the backside of the thin films [3,4]. The intermediate bi-layer structure of CuInSe 2 on CuGaSe 2 phases forms in the bulk of the film due to the difference in the reaction rates between the binary selenides.…”
