These techniques enable precise and scalable thin-film deposition, making them essential for printed solar cell manufacturing. The process starts with slot-die coating of the active layer. The ink is prepared by dissolving the active material in solvents and stirring at an elevated temperature. Once ready, the substrate is cut and placed on the vacuum chuck of the Slot-Die Coater, with the hot plate turned on to maintain the correct temperature. The slot-die head is assembled and mounted, and the ink is loaded into a syringe, connected to the slot-die head, and attached to a pump for controlled flow. After setting the coating speed and gap, the ink flows through the slot-die head, forming a meniscus, and the coating begins. A second stripe is applied before cleaning the slot-die head. Next, the hole-conducting layer is coated using the same slot-die process, with a slight offset to ensure proper alignment. Once both layers are in place, we use flexo printing to apply the silver back electrode. A flexo roller is installed and aligned with the pattern on the substrate. The silver paste is transferred onto the printing roller using a small paint roller and printed onto the coated stripes. This step is repeated for the second stripe, completing the structure. With the active layer, hole-conducting layer, and back electrode in place, the solar cell is now complete and ready for characterization. Slot-die coating and flexo printing offer a precise, scalable, and efficient approach to thin-film solar cell manufacturing.
