Effects of ZnS Buffer Layer on Performance of CIGS Solar Cell [PDF]

East European Journal of Physics
Cu(In,Ga)Se2 (CIGS)-based thin-film solar cells are currently among the most efficient. Zinc sulfide (ZnS) is the best buffer layer used in CIGS-based solar cells because it is non-toxic and has a wide band gap.

Unveiling a Near-Total Rear Passivation for High Performance of Ultra-Thin ACIGS. [PDF]

Adv Sci (Weinh)
Ultra‐thin solar cells of (Ag,Cu)(In,Ga)Se2 (ACIGS) suffer from rear interface recombination, limiting their performance. To tackle it, a full coverage plasma enhanced chemically vapor‐deposited 8 nm porous SiOx passivation layer was implemented and evaluated. It is shown that a combination of the near‐complete passivation from silica and the formation

BTO-Coupled CIGS Solar Cells with High Performances

, 2022
In order to improve the power conversion efficiency (PCE) of Cu(In,Ga)Se2 (CIGS) solar cells, a BaTiO3 (BTO) layer was inserted into the Cu(In,Ga)Se2. The performances of the BTO-coupled CIGS solar cells with structures of Mo/CIGS/CdS/i-ZnO/AZO, Mo/BTO ...

Different natures of sub-gap states in 135-CIGS/112-CIGS and 112-CIGS/135-CIGS heterostructures investigated by photoluminescence technique

Journal of Physics: Conference Series, 2018
CuIn1-xGaxSe2 (112-CIGS) has been proposed as a material for high efficiency thin film solar cells with reliably applicable photovoltaic properties. Higher efficiency devices can be achieved by various surface treatments and are believed to have Cu deficiency at the surface. One of the possible techniques is to have a very thin Cu-depleted surface, e.g.

Increasing the Effective Area of Small‐Sized CIGS Modules by Printed Ag Front Contacts

, 2022
Despite the high-efficiency potential of the Cu(In1-xGax)Se2 (CIGS) technology, its global market share is still relatively small. One reason for that is the comparatively low active module area caused by small cell widths and therefore the resulting ...

Engineering CIGS grains qualities to achieve high efficiency in ultrathin Cu(InxGa1−x)Se2 solar cells with a single-gradient band gap profile

Results in Physics, 2019
Reducing the Cu(InxGa1−x)Se2 (CIGS) thickness is an effective way to reduce the material use and increase manufacturing throughput. However, it is still a challenge to obtain high efficiency in the ultrathin CIGS solar cell.

Traces of iron impurities in copper sources can be a poison to Cu(In, Ga)Se2 solar cells

Nano Select, 2022
It has been widely accepted that the diffusion of iron from stainless steel substrates has detrimental impact on Cu(In, Ga)Se2 (CIGS) solar cell performance. However, the effect of traces of iron impurities in copper sources can be neglected all the time.
