just a video testing 2 different methods of encapsulating solar cells with EVA laminant. EVA is a clear, thin laminant that can be heated to encapsulate solar panels. Professional companies use it to encapsulate their solar panels by using machines that provide pressure and heat at the same time, to all sides of the panel. This combination allows the EVA to be vacuum-sealed to the solar cells, creating no air bubbles.
This allows long-lasting solar panels that are water and air-tight.
In this video I show you guys two different methods of encapsulating solar cells with EVA.
The first is by making a sandwich (Glass-EVA-Cell-EVA) and heating it. This method proved less effective and allowed large air bubbles to be present in front of the cells.
The second method is by sealing the EVA to the front of the cell and backing the cell with parchment paper to provide a heat-resistant, non-stick surface. The EVA was sealed on to the front of the cell, and then the cell were flipped over and placed on the glass, with the front of the cell already encapsulated. EVA was then sealed to the back of the cell, and to the glass. This method proved more effective as the front was encapsulated just as well as the back, and I will be using this method in making my solar panel.
