| titleOfInvention | Improve the electrochemical process for treating of copper-zinc-tin-sulfur film surface nature |
| abstract | The present invention relates to technical field of solar batteries, specifically disclosing improves the electrochemical process for treating of copper-zinc-tin-sulfur film surface nature, including step：Copper-zinc-tin-sulfur film material selenizing or sulfuration in constant-temperature tubular annealing furnace, are then placed within electrochemical workstation, only substrate and Mo back electrodes connection working electrode；1～2min of immersion in dehydrated alcohol is placed in, surface particles impurity is removed；Copper-zinc-tin-sulfur film material is put into processing solution, and processing solution is the mixed solution of 0.001～1M/L ethyls purpurine, two perchlorate, 0.001～1M/L hexafluorophosphoric acids, four butylamine and organic solvent；Apply the signal of telecommunication, the signal of telecommunication is any one of the cyclic voltammetric signal of telecommunication, the constant pressure signal of telecommunication, the constant current signal of telecommunication, the pulse voltage signal of telecommunication or the pulse current signal of telecommunication.The method of the present invention, effectively removes the high connductivity secondary phase on copper-zinc-tin-sulfur film surface, reduces the roughness of film surface, optimizes the interfacial characteristics contacted with Window layer, and environmental friendliness is with low cost. |
