Efficiency of earth abundant and pure sulfide kesterite Cu-Zn-Sn-S (CZTS) solar cell has been stagnant around 9.4% for years, while its counterpart Cu-In-Ga-Se (CIGS) reports an efficiency of more than 22%. Low open circuit ...

We report effects of an interface between TiO2−perovskite and grain−grain boundaries of perovskite films prepared by single step and sequential deposited technique using different annealing times at optimum temperature. ...

The non-stochiometric deviations in CZTS often results in certain detrimental point defects that act as trap centers causing non-radiative recombination and potential fluctuations, eventually results in large open circuit ...

In this work, the energy and flux of high energetic ions were controlled by RF superimposed DC sputtering process to increase the grain size and suppress grain boundary potential with minimum residual stress in Al doped ...

For the first time, room temperature heating free growth and crystallization of perovskite films in ambient air without the use of thermal annealing is reported. Highly efficient perovskite nanorod-based solar cells ...

Earth abundant kesterite copper-zinc-tin-sulfide-selenide (CZTS-Se) is considered as cost-effective material for next generation solar cells. However, current CZTS-Se solar cells have much lower efficiency than CIGS solar ...
