Title:
MANUFACTURING METHOD FOR HIGH-EFFICIENCY CIS/CIGS SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2019/105152
Kind Code:
A1
Abstract:
A manufacturing method for a high-efficiency CIS/CIGS solar cell: with dimethylformamide serving as a solvent, thiourea, a copper precursor compound, an indium compound or an indium and gallium precursor compound are sequentially dissolved in DMF to produce a clear and transparent precursor solution; the precursor solution is spin coated onto a piece of molybdenum glass, heated, and annealed to produce a CuInS2 or Cu(In,Ga)S2 thin film; the CuInS2 or Cu(In,Ga)S2 thin film undergoes a heated selenization in a Se atmosphere, then deposited by means of a chemical bath deposition method are CdS and a magnetron sputtering window layer ZnO/ITO, and an Ni/Al electrode is acquired by vapor deposition. The need to immerse in a toxic solution such as KCN and (NH4)2S is obviated for a sample acquired by pressurized selenization, thus preventing the production of Cu2-xSe, preventing safety and environmental hazards brought forth by same; therefore, a cell component achieving 10.4% in terms of efficiency can be manufactured without requiring KCN etching, and a wide range of market application values is provided.
