The successful isolation of phosphorene (atomic layer thick black phosphorus) in 2014 has
currently aroused the interest of 2D material researchers. In this review, first, the …

The non-toxic and wide bandgap material TiO2 is explored as an n-type buffer layer on p-
type Cu (In, Ga) Se2 (CIGS) absorber layer for thin film solar cells. The amorphous TiO2 thin …

This study describes in detail the effects of sodium and potassium on Cu (In, Ga) Se 2
(CIGS) absorbers and solar cells. We report on the influence of these species on the surface …

Cadmium free ZnS buffer layers were deposited on Cu 2 ZnSn (SSe) 4 (CZTSSe) absorber
layer by chemical bath deposition method. The thickness of ZnS buffer layers was tuned by …

Herein, a novel combination of Mg‐and Ga‐co‐doped ZnO (MGZO)/Li‐doped graphene
oxide (LGO) transparent electrode (TE)/electron‐transporting layer (ETL) has been applied …

ZnMgO thin film is a potential buffer layer in Cu (In, Ga) Se2 (CIGS) solar cells. ZnMgO film
can be uniformly deposited, and the composition of Mg can be precisely controlled by the …

In this work, we discuss two alternative structures of CIGS-based solar cells, a bi-facial
configuration and a back-wall configuration. One of the critical issues in these structures is …

Sulfur-based metal chalcogenide films have been widely used for high-performance
optoelectronic devices due to their attractive optical and electrical properties. Although …

Abstract We fabricated Cu 2 ZnSn (S, Se) 4 (CZTSSe) solar cells with (Zn, Mg) O buffer
layers as an alternative to the CdS buffer layer for the improvement of cell performance …

For the fabrication of high efficiency Cu (In, Ga) Se2 (CIGS) solar cells, a CdS thin film is
usually used as the buffer layer. However, since Cd is toxic and also a hazardous material …
