INFLUENCE OF INKJET PRINTING PARAMETERS ON PEROVSKITE-BASED PHOTOVOLTAIC CELLS

摘要

The photovoltaic research has recently paid great attention on the perovskite compounds and their noteworthy potential to be processed by scalable low-cost deposition methods, like inkjet printing. The employment of this digital technology in perovskite-based photovoltaics is currently limited by issues related to the need of producing smooth, compact photoactive layers with suited cristallinity. In this work, a study of the effect of the printing parameters on the morphology and optical properties of printed perovskite layers obtained through a double-step process is reported. The electrical characteristics of the solar cell devices printed with a different nozzle number have indicated that the best performances can be reached with a working condition at reduced number of multiple simultaneous droplets.
