Abstract
We report scalable deposition of perovskite thin film by blade coating and slot-die coating towards large-area perovskite solar cell and module development. We find that extending perovskite ink processing window is critical to transitioning from laboratory-scale spin coating to scalable deposition. Using blade coated perovskite thin films, we demonstrate perovskite mini-modules with efficiency near 16. Using slot-die coating, we show uniform deposition of perovskite thin films on substrate with area larger than 200 cm 2 . Using slot-diecoated perovskite thin films, we obtain perovskite solar cells with efficiency higher than14. Further optimization of coating conditions is expected to improve device performance comparable to those prepared by spin coating for small area devices.
