Learning know-how on fabrication and encapsulation of 10 cm x 10 cm perovskite modules
There is a huge gap between making small cells and modules. Conveniently, multiple stand alone perovskite cells (~0.1 cm square) can be made by spin coating techniques. Meanwhile, the policy makers and community at large want to see data obtained from modules at real outdoor conditions, leaving small cells tested under simulated and controlled ambient less relevant to paving way for perovskite PV to enter market. Our project aims to provide evidence of outdoor testing of solution-processed emerging PV suitable and potential for cloudy climate such as that of the UK. We clearly see VIPERLAB as an accelerator for us to establish the know-how and minimize resource waste in shifting from small cell to a minimodule 10 cm x 10 cm. By the end of our project (2024), we will also develop larger 30 cm x 30 cm modules. Instead of conducting a specific experiment, it would be a great gain for us to learn know-how and establish our baseline alike to other more experienced research groups.
