The absorber layer of CZTS solar cell is a compound semiconductor which has favourable optical and electrical properties. Researchers are highly interest to investigate the CZTS solar cells for its earth abundant, non-toxic and low cost feature. Consequently, the absorber layer of CIGS is replaced to CZTS absorber layer. In this research work, the potentiality of Molybdenum Sulphide (MoS2) as buffer...
The Cu2ZnSnS4 is a quaternary semiconductor compound has recently been drawn the attention of extensive research as a potential absorber layer since its offers favourable optical and electronic properties along with low cost material. In this research work, the deep level defects on the performance of CZTS solar cells with Bismuth Sulphide (Bi2S3) buffer layer was carried out by numerical analysis...
In this work, a numerical analysis on cadmium stannate (Cd2SnO4) as front contact, zinc stannate (Zn2SnO4) as buffer layer and antimony telluride (Sb2Te3) with molybdenum (Mo) as back contact has been conducted in the conventional (SnO2/CdS/CdTe/Ag) CdTe cell structures. Here, CdS window layer is replaced by zinc cadmium sulphide (ZnxCd1−xS) aiming to improve efficiency and stability utilizing Analysis...
Cadmium telluride (CdTe) polycrystalline thin-films have long been recognized as a leading material in realizing cost effective and reliable photovoltaic (PV) cells. The formation of a stable, low resistance, non-rectifying contact to p-CdTe is one of the major and critical challenges associated with this kind of solar cells. The aim of this work is the systematic investigation of back-contact materials...
