Today's Photovoltaic module production is driven by cost. Due to its high conductivity and solderability the precious metal silver is used in standard solar cell production as base material for solder pads. The need for replacing the costly silver em

Soldering is the most common way to interconnect solar cells into strings to form a PV module. The most prevalent and standard solder material is the SnPbAg-solder. Since lead is a hazardous material and the RoHS-guideline is expected to prohibit its

Air-breathing PEMFCs consist of an open cathodic side to allow an entirely passive supply of oxygen by diffusion. Furthermore, a large fraction of the produced water is removed by evaporation from the open cathode. Gas diffusion layers (GDLs) and the
The tabbing step is a critical process step in module manufacturing. Defective solder joints lead to an increased series resistance, a lower fill factor and to mechanical stability problems. Out of several image-based methods, such as PL, PL-j 0 , EL

This paper presents a model-based analysis of a proton exchange membrane fuel cell (PEMFC) with a planar design as the power supply for portable applications. The cell is operated with hydrogen and consists of an open cathode side allowing for passiv

A new type of planar fuel cell based on printed circuit board (PCB) technology has been developed. This planar design consists of an open cathode side which allows a completely passive, self-breathing operation of the fuel cell. Power densities of 10

The interconnection of busbar-free solar cells by multiple wires is a simple and evolutionary concept to lower the cost of PV modules by reducing silver consumption for the front side metallization and to increase the module efficiency by lower serie

Wafer-based PV modules, which accounted for 87% of the market in 2010 [1] , include soldered cell strings. Yet, soldering is a critical process for the production yield because it introduces severe thermo-mechanical stress into the cell. The quality
