In perovskite solar cells using plastic films, flexibility is important. Flexibility of moisture barrier films is also necessary. In our research on perovskite solar cells on film substrates, we have been investigating a method involving direct lamination of ITO-PET film for electrodes on a spiro-OMeTAD layer, which serves as a hole transport layer. This method includes pressing ITO-PET film onto the fabricated film-type solar cell, followed by applying a hot melt film and moisture barrier film, and then applying pressure using heat press equipment. However, while the use of hot melt film minimizes the impact on the perovskite layer post-lamination, ensuring adhesion requires sophisticated equipment such as a 20kN screw-type heater press (NP Systems N4053-00), indicating that simpler methods were insufficient. Therefore, we have redesigned evaluation cells to validate different types of barrier films and sealants, considering methods involving heat laminators to facilitate roll-to-roll processing, particularly when using thermosetting sealants.
