Perovskite quantum dots (PQDs) are semiconductor nanocrystals that have received tremendous attention in photovoltaic devices due to their exceptional optical and electronic properties. PQD solar cells (PQDSCs) have shown great potential to overcome many drawbacks of their large-grain perovskite thin-film (often called bulk) counterparts, such as high defect tolerance and better stability due to the controlled surface properties of the quantum dots. Over the past few years, PQDSCs have shown a quick increase in efficiency, already exceeding 16%, and high stability. However, the fabrication of these solar cells is based on the spin-coating technique, which leads to significant waste. In this work, we develop and optimize a printing process for PQDs layers and study them with various techniques such as UV-Vis, scanning electron microscopy and X-ray diffraction to achieve an up scalable fabrication of PQDSCs.
