The CuZnSn(CZT) precursor thin films are grown by ion-beam sputtering Cu, Zn, Sn targets with different orders and then sputtering Se target to fabricate Cu_2Zn
Mesoporous tin oxide(SnO_2/ with a high surface area of 147.5 m~2/g has been successfully synthesized via self-assembly process, combining the driven forces of
