WELCOME ADDRESS
Coordinator's message

Welcome to the seven VIPERLAB Newsletter

 

Greetings VIPERLAB Community,


As we reflect on our recent third yearly meeting, we are both proud and inspired by the tremendous progress and achievements we have made over the past year.

Our dedicated efforts in sharing VIPERLAB infrastructures and conducting joint research activities targeting harmonised procedures for fabrication, characterisation, and life cycle analysis, have created VIPERLAB as a recognisable brand in the perovskite community.

With just six months remaining in the VIPERLAB project, our focus is now on the dissemination and exploitation of the wealth of results we have accumulated over the past three years.

We would like to highlight some upcoming events where VIPERLAB will be actively participating. These include the Quantsol and ISOPHOS summer schools, the VIPERLAB Public Event at EUPVSEC in Vienna, and the ISOS-15 conference in Berlin.

These events offer unique opportunities to engage with leading experts, share knowledge, and discuss the future of perovskite PV technologies. Detailed information about these events can be found later in this newsletter.

Thank you for being an integral part of VIPERLAB's journey and success.

 

 Stay connected for exciting updates!

VIPERLAB ACTIVITIES

     

 
     

Round Robins are moving forward!

 

In the framework of the VIPERLAB project, four Round Robins have already been completed: two focused on measurement and two on aging. During these rounds various protocols and configurations were thoroughly evaluated. Additionally, at present two rounds are underway, one dedicated to measurement and the other to aging, specifically involving tandem PSK/Si solar cells.

The current measurement Round Robins involves a benchmarking study to compare different measurement protocols uses for tandem devices. Insights from the previous Round Robins can be summarised as follows:

Firstly, when comparing measurements taken before and after the samples were shipped to the measuring labs, it was detected that the short circuit current was influenced by these measurements. Additionally, the open circuit voltage was found to be slightly influenced. The mean value for the fill factor appeared to be stable, although silver paste had to be added to some of the substrates to maintain consistency. These findings highlight the importance of using stable cells and reducing waiting periods, ensuring consistent contacting procedures, performing EQE or using adapted spectral mismatch correction, controlling and monitoring temperature, and utilising appropriate spectral distribution for tandem cells.

Moreover, using larger cells can help avoid issues related to mask positioning. A shorter protocol to determine performance could potentially be sufficient to extract the necessary electrical parameters. It would be advantageous to exchange a reference cell, ideally a filtered silicon cell, to ensure that all laboratories operate with the correct irradiance settings. This would help standardise measurements and improve consistency across different labs.

As early as the results of the new measurement Round Robin are obtained, they will be disseminated for further discussion with the community.

 

UPCOMING EVENTS ON PV
