Improving the light trapping in a module results in an increase in the generated current. Consequently, an optimization of the front grid metallization of the cell is required for the best trade-off between series resistance, ...

We investigate the optical properties of n- and p-type polycrystalline silicon (poly-Si) layers. We determine the optical constants n and k of the complex refractive index of polycrystalline silicon by using variable-angle ...

We report on ion-implanted, inkjet patterned back junction back contact silicon solar cells with POLysilicon on Oxide (POLO) junctions for both polarities – n+ doped BSF and p+ doped emitter. The recombination behavior is ...

Kerfless wafering techniques have the potential to reduce the cost of crystalline silicon (Si) in photovoltaics by saving material and production costs. Thermomechanical spallation from thick wafers with aluminium (Al) in ...

The back end process of passivated emitter and rear cells (PERC) consists of at least one laser process and three screen-printing steps followed by the stringing and tabbing of the cells. To reduce the number of steps we ...

A potentially cost-effective ion implanter for solar cells has become commercially available very recently. As the emitter dopant profiles differ from the standard diffusions, a combination of process simulation and device ...

We combine two kerfless approaches to unite advantages of both processes: the epitaxial layer transfer based on porous silicon (PSI process) and the lift-off of a thin silicon layer from a substrate via controlled spalling ...

We measure the three dimensional movement of cracked solar cell parts in standard sized PV-modules during a four line bending test. We develop a model which explains this movement assuming that the centers of mass of the ...
