In 2025, certified efficiency up to 27% has been demonstrated using Perovskite Solar Cells.[1] Also, many progresses have been done on encapsulation to improve their stability.[2] These results are showing their potential for the next generation of photovoltaic device. This explain why some industrials are now investigating this field and start to build their pilot and fabrication lines. So far most of high efficiency devices have been achieved using the DMF / DMSO solvent system with an antisolvent step using chlorobenzene.[3] This approach is very sensitive to the antisolvent step and has a narrow processing window which might make it difficult to scale up. Other approaches rely on the use of nitrogen or vacuum quenching which might be costly due to the high amount of high purity gas use during the nitrogen quenching step and the slow speed of the vacuum quenching respectively.[4] Here we present our work on inkjet printed perovskite using a relatively unexplored solvent with low toxicity, 1-methoxy-2-propanol. By using different additive we show that we can control the crystallization kinetic to make compact perovskite layer without any quenching and achieve device efficiency over 20%.
