Claim:
1. A method for improving mass-production yield of large-area organic solar cells comprising steps of: rolling out a substrate; disposing a plurality of active-layer materials on a surface of said substrate rolling continuously at room temperature for forming an active layer, and said plurality of active-layer materials include an electron donor material, an electron acceptor material, and an additive; enabling said substrate rolling continuously to enter an oven, and adjusting a baking temperature of said oven such that said additive departs when the wet film transforms to a dry film and said active layer solidifies; and rolling and collecting said substrate; where said additive is 1,8-diiodooctane; wherein said baking temperature of said oven is adjusted dynamically between 70 and 150° C.
