Effect of Humidity During Perovskite Photovoltaic Ink Deposition

As stated in our Perovskite Solar Cell Fabrication Guide, it is essential that humidity is no higher than 40% whilst depositing the perovskite precursor ink onto the PEDOT:PSS coated substrates. In the following video, Ossila Research Scientist Dr. Darren Watters performs an experiment to demonstrate the effects of high humidity on perovskite films.

If you have any questions regarding the I101 Perovskite Precursor Ink, need any technical advice on fabricating perovskite solar cells, or would like a recommendation for a high quality dehumidifier, please get in touch with us and we'll be happy to help.

 

In this video, Dr. Darren Watters demonstrates how high humidity during perovskite ink deposition can reduce the performance of perovskite solar cells.
