Critical role of Zn/Sn ratio to enhance Cu-Zn-Sn-S solar cell eﬃciency by suppressing detrimental Cu2-xS secondary phase

Kaur, K.; Sood, M.; Kumar, N.; Nazari, H.H.; Gudavalli, G.S.; Dhakal, T.P.; Kumar, M. (2018-09-25)

The co-existing secondary phases, in oﬀ-stoichiometric Cu-Zn-Sn-S (CZTS) solar cells, are one of the main causes of performance gap between earth abundant CZTS and matured Cu-In-Ga-Se (CIGS) solar cells technology. Highly ...
Nanoscale charge transport and local surface potential distribution to probe defect passivation in Ag doped Cu2ZnSnS4 absorbing layer

Kaur, K.; Arora, K.; Behzad, B.; Qiao, Q.; Kumar, M. (2019-01-02)

The performance of earth abundant Cu2ZnSnS4 (CZTS) material is limited by high deﬁcit of open circuit voltage (VOC) which is mainly due to the easy formation of CuZn antisite defects. Suppression of CuZn defects is thus ...
A study to control secondary phases and defects in Kesterite Cu2ZnSnS4 absorber layer for photovoltaic applications

Kaur, K. (2022-09-23)

Chalcogenide based quaternary compound: Cu2ZnSnS4 (CZTS), a Kesterite material, has been identified as a potential absorber for thin film solar cells. Salient features of CZTS such as, high absorption coefficient (>104 ...
