Moisture ingress in photovoltaic (PV) modules is the core of most degradation mechanisms that lead to PV module power degradation. Moisture in EVA encapsulant can lead to metal grids corrosion, delamination and discolouration of encapsulants, potential induced degradation, optical and adhesion losses.

• To reduce the weight of these modules, some manufacturers are using thinner glass and/or thinner frames, which can reduce rigidity and durability. Second, reductions in inter-cell spacing, which are achieved through shingling and other cell-to-cell interconnection techniques, could increase mechanical stress on solar cells.
Modules based on c-Si cells account for more than 90% of the photovoltaic capacity installed worldwide, which is why the analysis in this paper focusses on this cell type. This study provides an overview of the current state

The photovoltaic effect is a process that generates voltage or electric current in a photovoltaic cell when it is exposed to sunlight. It is this effect that makes solar panels useful, as it is how the cells within the panel convert sunlight to electrical energy. The photovoltaic effect was first discovered in 1839 by Edmond Becquerel. When doing experiments involving wet cells, he noted that

The weight ratio between the donor polymer and acceptor fullerene in the final film has a large effect on the PCE of an OPV device. The ideal or correct weight ratio is usually defined as the ratio that achieves the highest PCE.
