Improving performance of Cu2ZnSnS4 solar cell via back contact interface engineering

Publikováno v: Solar Energy. 230:986-995

Although kesterite Cu2ZnSnS4 (CZTS) has emerged as a potential absorber material for development of low cost thin film solar cells, the performance of the CZTS devices has been limited by a large deficit in open circuit voltage caused by recombinatio

Influencing mechanism of post-sulfurization with sulfur flakes on phase evolution and Schottky diode characteristic of Cu2ZnSnS4 thin films sputter deposited from a single target

Autor: Bhaskar Chandra Mohanty, Kaushlendra Pandey

Publikováno v: Solar Energy. 228:333-338

While single target sputter deposition appears very attractive to prepare kesterite Cu2ZnSnS4 (CZTS) thin films for photovoltaic applications, the growth of secondary phases arising as a consequence of stoichiometric deviation stemming from variation

Critical Influence of Annealing Configuration in Kesterite Phase Evolution During Growth of Cu2ZnSnS4 Thin Films from Non-Toxic Environment-Friendly Solutions

Autor: Indu Gupta, Kaushlendra Pandey, Alok Kumar Jain, P. Malar, Bhaskar Chandra Mohanty

Publikováno v: Journal of Electronic Materials. 50:1314-1322

While preparing Cu2ZnSnS4 (CZTS) thin films via non-toxic solution based approaches, it is critical to suppress the formation of secondary phases as they adversely affect solar cell performance. During post-deposition annealing of the precursor film�

Evaluating the role of precursor concentration in facile conformal coating of sub-micrometer thick Cu2ZnSnS4 films using non-toxic ethanol based solutions

Autor: Kunal J. Tiwari, P. Malar, Indu Gupta, Bhaskar Chandra Mohanty

Publikováno v: Applied Surface Science. 494:795-804

Although non-toxic solution processing offers a scalable approach for growth of Cu2ZnSnS4 (CZTS) thin films, it must suppress the formation of secondary phases and yield facile conformal large grained films with minimum process steps. While growing C

Eliminating secondary phases: Understanding kesterite phase evolution of Cu2ZnSnS4 thin films grown from ethanol based solutions with high photosensitivity

Autor: Bhaskar Chandra Mohanty, Indu Gupta

Publikováno v: Solar Energy. 181:214-221

Non-toxic solution based approaches need to suppress the formation of secondary phases in the growth of Cu2ZnSnS4 (CZTS) thin films, which otherwise detrimentally affect the device performance especially by limiting the open circuit voltage. While gr

Growth control of molybdenum thin films with simultaneously improved adhesion and conductivity via sputtering for thin film solar cell application

Autor: Neetu Bansal, Kaushlendra Pandey, Kulvir Singh, Bhaskar Chandra Mohanty

Publikováno v: Vacuum. 161:347-352

Thin molybdenum (Mo) films have been recognized as an effective bottom contact in Cu2ZnSnS4 (CZTS) based thin film solar cells. In typical deposition settings, the Mo films are required to have a favourable microstructure that facilitates sodium diff
