Photovoltaic Panel with Removable Solar Cells

With the aim of meeting the needs of both the energy transition and the circular economy, it is imperative to develop photovoltaic panels with removable solar cells that can be reconditioned. We present a configuration of such a panel with three variants of charges collections on the front face. These three variants were fabricated and assembled in an inert environment (N2 glovebox). Their PV performances before and after a test degradation were analyzed. Anticipating an issue concerning ageing, H20 and O2 sensors were integrated into the prototypes to assess ant interpret the evolution of PV performances in a climatic chamber. The results, both in terms of tightness and PV performance degradation, are satisfactory, especially for one of the variants. Several improvements are proposed.
