Design optimization of photovoltaic arrays on curved surfaces
2018 Design, Automation & Test in Europe Conference & Exhibition (DATE), 2018Flexible photovoltaic (PV) arrays often have to be mounted on surfaces that have a significant amount of curvature. These include solar-powered vehicles, planes, and also some wearable devices. However, this inevitably leads to non-uniform solar irradiance among connected PV cells.

Photovoltaic array loss mechanisms
Solar Cells, 1986Loss mechanisms which come into play when solar cell modules are mounted in arrays are identified. Losses can occur either from a reduction in the array electrical performance or with nonoptimal extraction of power from the array. Electrical performance degradation is caused by electrical mismatch, transmission losses from cell surface soiling and ...
