Interconnection of perovskite/Si solar cells with low Power Conversion Efficiency loss (D4.1, M12 - October 2023)

In this deliverable, PEPPERONI partners from CSEM present insights into the interconnection of perovskite/Si tandem solar cells using electrically conductive adhesives (ECA). The objective was to identify ECAs and curing conditions that minimise power conversion efficiency (PCE) losses while considering other factors influencing the perovskite material and causing its degradation. Within the task, partners demonstrated an assembly of a string comprising of four perovskite/Si tandem solar cells. Different protocols have been tested to ensure the process efficiency and set up the basis for further developments. These will involve the evaluation of further ECA compositions.
