Abstract

Thin films of Cu2ZnSnSe4 (CZTSe) with copper de�ficiency and zinc excess were fabricated at Northumbria University by the selenisation of metallic precursors deposited on Mo/glass and bare glass substrates. Absorption and photoluminescence (PL) measurements were used to examine the �film on glass whereas fi�lms on Mo/glass were used to produce a solar cell with ef�ficiency of 8.1%. Detailed temperature and excitation intensity analysis of PL spectra allows identifi�cation of the main recombination mechanisms as band-to-tail and band-to-band transitions. The latter transition was observed in the spectra from 6 to 300 K.
