Optoelectronic characterization of perovskite mini-modules
The proposed work aims to explore a novel approach for the measurements of the spectral response of mini-modules. The novel approach will utilize strip illumination so as to avoid the necessity of illuminating the whole device. In addition to this, measurement of the performance of several perovskite mini-modules will be conducted as part of an inter-comparison campaign between the host organization (AIT) and the University of Cyprus (UCY). Spatially-resolved techniques (Electroluminescence, Photoluminescence and Lock-In Thermography will be utilized for the characterization of the modules as well.

How would you describe your experience with the VIPERLAB opportunity? How did the experience/visit at AIT (ECH) meet your expectations?
Great experience. My visit at AIT was a positive experience and met my expectations.
Did you face any difficulties during your visit or application process?
No difficulties.
Does this VIPERLAB experience at AIT (ECH) bring you closer to your research objectives? How?
The testing and measurement of PV samples as a part of inter-comparison campaign between the host organization (AIT) and my institute (UCY) assisted in gaining confidence about the measurement capability of the infrastructure built at UCY.
What other VIPERLAB activities have you participated in, or would you like to participate in?
I have participated in another VIPERLAB activity with HZB (stability lab) regarding stability testing of perovskite mini-modules.
Do you intend or already did publish/present your collected results in a paper or conference?
We are planning to present the results in a conference or paper. We will mention the financial support from Viperlab.
