The Challenges of Scale for Printed Perovskite

Whilst the photovoltaic performance of perovskite solar cells continues to increase, technology developments are also progressing in the area of printing and processing in order to realise large scale manufacture. Possible methods for both depositing the layer stack and its subsequent heating are numerous; to deliver a working and scalable device stack can require a hybrid approach where multiple printing techniques are employed. This talk will introduce a series of technology developments required to enable the continuous fabrication of perovskite solar cells at commercial scale using both R2R and S2S processing.
A layer by layer approach to coating deposition will be presented including the mechanism and process parameters required to successfully deposit the entire device stack via screen printing and slot die coating. This talk will consider the trials and tribulations of manufacturing perovskite solar cells at scale on glass and flexible PET substrates, in particular delivering an assessment on the matching of device architecture to deposition method to substrate with the view of unlocking large-scale production.
