A High Voltage MWT Module with Improved Shadow Performance
conference paper
In this paper we present a module concept designed for better performance under shadow conditions, incorporating also lower BOS costs. This concept is a high-voltage, low-current, shadow resistant, back-contact module concept. The experimental results under partial shading conditions for mini-modules having a Voc of 39.8V show a substantial improvement in shadow performance. The concept is based on the existing ECN MWT (Metal Wrap Through) back-contact technology [1], where the standard MWT cells are replaced by series connected mini߿ݠcells. With the flexibility of the back-foil system we are able to approach a more linear shadow response for our module.
