Abstract:
CZTS1-xSex and ABX3 (where A = CH3NH3
+, HC (NH2)2
+, CS+, Rb+; B = Pb2+, Sn2+, Sb2+;
X = Cl, Br-, or I-), have received much attention from the scientific community as light absorbing
semiconductor materials. Their high absorption coefficient makes them very attractive for solar
cells applications [1,2].
The general structure of the solar cells has the following sequence: the transparent
conducting oxide (TCO - fluorine-doped tin oxide: FTO or indium tin oxide: ITO) / the electron
transport layer (ETL) / the absorber layer (CZTS1-xSex or ABX3) / the hole transporting layer
(HTL) / the metal electrode.
