Determining the decomposition voltage of Cu(In_1-xGa_x)Se₂

Partial shading of CIGS modules can lead to permanent damage of the module in the shaded area. This is caused by harmful reverse bias voltages in the shaded area which lead to reverse bias induced defects, also known as wormlike defects. A lot is already known about the origin and propagation of wormlike defects. However, the fundamental...

The Need for a New Parameter on PV Modules Datasheet: Shading Tolerability

This paper suggests a measurable parameter, the so-called Shading Tolerability (ST), to be added on PV modules datasheet. Using this parameter, PV modules can be compared and classified regarding the ability to oppose shading effects. The parameter is extracted based on mathematical and probability analysis, then measured using a Large Area...
