Disclosed is a polyimide film prepared from an aromatic tetracarboxylic acid component and an aromatic diamine component, which has a dimensional change from 25 °C to 500 °C within a range of from -0.3 % to +0.6 % based on the initial dimension at 25 °C. The polyimide film may be used as a substrate for a CIS solar cell. |
