Luminescence of Cu2ZnSnS4 polycrystals described by the fluctuating potential model

Autor: Budhika G. Mendis, Ken Durose, M. C. J. Goodman, Douglas P. Halliday, Jonathan D. Major, Richard Claridge

Publikováno v: Journal of applied physics, 2013, Vol.113(22), pp.223503 [Peer Reviewed Journal]

The growth of Cu 2ZnSnS4 (CZTS) polycrystals from solid state reaction over a range of compositions, including the regions which produce the highest efficiency photovoltaic devices, is reported. X-ray measurements confirm the growth of crystalline CZ

The nature of electrostatic potential fluctuations in Cu2ZnSnS4 and their role on photovoltaic device performance

Autor: Budhika G. Mendis, M D Shannon, Jonathan D. Major, Douglas P. Halliday, M. C. J. Goodman, Aidan A. Taylor, Ken Durose

Publikováno v: Journal of Physics: Conference Series. 471:012014

Aberration corrected STEM EELS is used to investigate point defects in Cu2ZnSnS4 (CZTS). Nano-scale clusters of ZnCu anti-site donors are observed with the donor concentration being sufficiently high to degenerately dope the semiconductor. Uncompensa

The role of secondary phase precipitation on grain boundary electrical activity in Cu2ZnSnS4 (CZTS) photovoltaic absorber layer material

Autor: Douglas P. Halliday, Ken Durose, M. C. J. Goodman, Jonathan D. Major, Budhika G. Mendis, Aidan A. Taylor

Publikováno v: Journal of Applied Physics. 112:124508

Cathodoluminescence is used to measure the recombination velocity of the heterointerfaces between Cu2ZnSnS4 (CZTS) and CuxSnySz, SnS secondary phases precipitated along the grain boundaries as well as ZnS precipitated within the CZTS grain interiors.
