The angle-dependent spectral response is measured for six differently textured silicon solar cells before and after encapsulation. Deviations from Lambert's cosine law and differences due to the textures can be clearly determined by means of an uncer

Understanding the origin of thermomechanical stress in solar cells is a key factor to extend the lifetime of photovoltaic modules. However, the methods to determine the stress are very limited. With the confocal micro-Raman spectroscopy, we present a

This study analyses thermomechanical stresses in silicon solar cells after the soldering process by finite element modeling. An experimentally validated model shows compressive and tensile stresses, longitudinal and transversal to a busbar or a pad r

Raman spectroscopy is used for measuring stress in microelectronic devices [1] as well as in solar cells [2, 3]. However, on PV module level it has not been examined yet. We transfer the method in order to enable the experimental determination of the

Despite having generally excellent corrosion resistance copper is still susceptible to several forms of corrosion. To obtain accurate and current information about atmospheric corrosion of copper in Europe, two different approaches are implemented. T

This work presents an interconnection approach for 6” back-contact back-junction (BC-BJ) solar cells by using conventional solder-coated copper ribbons with implemented wave structures for thermomechanical stress relief. We developed a process for

In this paper we propose a method to predict hot spot temperatures in crystalline silicon photovoltaic modules operating under critical shading conditions prior to module fabrication. We developed a unique tool to evaluate the damage risk potential f

The power output and efficiency of a crystalline silicon PV module is a highly relevant quantity to evaluate novel cell, material and design technologies. It is therefore necessary to develop a full understanding of the different factors that impact

Small photovoltaic reverse osmosis systems (PV-RO) without batteries are not driven constantly at their operating point, but are tracked to the solar power offered. Because of this intermittent and dynamic operation, high requirements for the operati
