The latest progress and future perspectives of thin film photovoltaic kesterite technology are
reviewed herein. Kesterite is currently the most promising emerging fully inorganic thin film …

Abstract Kesterite structure semiconductor Cu 2 ZnSn (S, Se) 4 is one of the most promising
candidate as a light absorber material to overtake the next generation of thin film solar cells …

As a low‐cost substitute that uses no expensive rare‐earth elements for the high‐efficiency
Cu (In, Ga)(S, Se) 2 solar cell, the Cu2ZnSn (S, Se) 4 (CZTSSe) solar cell has borrowed …

The defects states and carrier density of CZTSe absorber layers are two of the crucial factors
that decide the photovoltaic performance of CZTSe thin film solar cells. Fine tailoring the …

Sodium treatment of kesterite layers is a widely used and efficient method to boost solar cell
efficiency. However, first experiments employing other alkali elements cause confusion as …

The performance‐boosting effect of alkali treatments is well known for chalcogenide thin‐
film solar cells based on Cu (In, Ga) Se2 (CIGS) and Cu2ZnSn (S, Se) 4 (CZTSSe–kesterite) …

This work presents a comprehensive analysis of the structural and vibrational properties of
the kesterite Cu2ZnSnS4 (CZTS, I 4̅ space group) as well as its polymorphs with the space …

Low open circuit voltage (V OC) has been recognized as one of the principle limitations in
the current generation of kesterite based solar cells. In order to investigate the origin and …

Isoelectronic cation substitution is a potential method to decrease the density of Cu‐Zn anti‐
site defects in CZTSSe, thus improving the VOC and performance of CZTSSe solar cells …

It is very important to understand why a small amount of alkali metal doping in Cu 2 ZnSn (S,
Se) 4 (CZTSSe) solar cells can improve the conversion efficiency. In this work, Na-doped …
