Fabrication of solar cells based on Cu2ZnSnS4prepared from Cu2SnS3synthesized using a novel chemical procedure

Abstract: Solar cells based on kesterite-type Cu2ZnSnS4 (CZTS) thin films were fabricated using a chemical route to prepare the CZTS films, consisting in sequential deposition of Cu2SnS3 (CTS) and ZnS thin films followed by annealing at 550 • C in nitrogen atmosphere. The CTS compound was prepared in a one-step process using a novel chemical procedure consisting of simultaneous precipitation of Cu2S and SnS2 performed by diffusion membranes assisted CBD (chemical bath deposition) technique. Diffusion membranes were used… Show more

“…This system also includes a pumping system and an electronic control proportional integral differential (PID) of the solution temperature. Details of the deposition system and of the possible reaction mechanism for the formation of the Cu 2 SnS 3 compound are given by Correa et al 14 The preparation of Cu 2 ZnSnS 4 films was achieved by sequential deposition of Cu 2 SnS 3 and ZnS films followed by annealing at 550 °C in sulfur ambient. The synthesis of the Cu 2 SnS 3 films was performed using the procedure described above and the ZnS films were deposited by conventional CBD method using a solution containing thiourea (CSN 2 30, 400 and 45 mM, respectively.…”

“…The ZnS layer was deposited by the conventional chemical bath deposition (CBD) method and the compound Cu 2 SnS 3 was grown in a onestep process using a novel chemical procedure which includes simultaneous precipitation of Cu 2 S and SnS 2 performed by diffusion membrane assisted CBD technique to achieve a moderate control of release of metal ions into the work solution, details are given by Correa et al 14 It is well known that in a CBD process, the controlled release of precursor ions to the work solution favors the ion by ion growth. 15 Therefore, we consider that a controlled release of ions achieved by the physical barrier provided by the diffusion membrane favors the growth ion by ion and prevents the cluster formation.…”
