“…With its high bandgap of E g = 1.68eV at room temperature and optical absorption coefficient larger than 10 4 cm -1 for photon energies hν > 1.7eV, CuGaSe 2 is a promising absorber for thin-film solar cell devices. Up to now energy conversion efficiencies of 9.7% and 9.5% have already been achieved for single-crystal [1] and thin-film cells [2], respectively. A pronounced degradation of ZnO/CdS/CuGaSe 2 solar cells was found, when the CuGaSe 2 absorber films were exposed to air before deposition of CdS [3].…”

The thermal and native oxidation of CuGaSe 2 thin films was studied by in-situ X-ray photoelectron spectroscopy (XPS). The special design of the XPS chamber allowed to measure XP-spectra under oxidizing gas atmospheres at pressures of up to 5mbar (in-situ) or in ultra high vacuum (UHV). During thermal oxidation, the formation of predominantly Ga 2 O 3 and some amount of SeO 2 were observed, but no copper oxides could be detected in the near surface region of the thin films. The same oxides were found after native oxidation in air under ambient conditions. Only after long term native oxidation for longer than four months Cu(OH) 2 was detected. An additional sodium oxide compound formed at the thin film surface, Na x O and Na 2 CO 3 after thermal and native oxidation, respectively. The amount of these sodium oxide compounds depends on the Na content on the as prepared surface. The formation of SeO 2 under humid conditions at 100°C was found to depend on the surface composition of the thin film.

This review points out the current need for further research on tandem solar cells as the commercial single‐junction solar cell technologies report close to their maximum performance limit. First, the conceptual insight and the desired interconnection schemes for tandem solar cells are briefly presented. Then, a comprehensive discussion on the structural, optical, and electronic properties of CuGaSe2, evaluating its use as a top cell absorber material, is presented. Furthermore, the current status and the critical analysis of CuGaSe2 solar cells, which finds that the adapted conventional device architecture possesses severe limitations, are presented. Based on the drawbacks of the existing materials in use, new materials to fabricate CuGaSe2 solar cells are proposed. Also, tandem configurations with newly proposed CuGaSe2 solar cell architecture by choosing Si photovoltaics as bottom cells are devised. In the end, further challenges in the devised tandem configurations with a focus on their band alignments are elucidated.
