| description | A method for preparing compact CuInSe2 thin film on flexible substrates belongs to the photovoltaic cell technical field, which is characterized in that the method comprises the following steps: preparing Cu-In alloy prefabricated film on a metallic titanium flake or on a stainless steel flake by adopting the constant-current co-electrode position method, seleniding the Cu-In alloy prefabricated film in selenium steam, wherein selenylation treatment temperature is 250-300 DEG C, holding time is 30-40min, then obtaining the CIS thin film which is accord with stoichiometry, compacting the CIS thin film, one of the compacting is under room temperature, and pressure intensity is 150-200MPa, the other compacting is that compacting after heating moulds and samples to 40-60DEG C, and pressure intensity is 300-600MPa, carrying out the heat treatment to the compacted CIS thin film, treatment temperature is 400-500 DEG C, holding time is 30-60min, and finally obtaining the compact CIS thin filmwhose surface is smooth. |
