From today's viewpoint future solar cells will be thinner, of higher efficiency and produced in greater numbers. A solar cell concept able to fit these developments could be the passivated emitter and rear cell. With a new laser-based process (laser-

Damage-free reactive ion etch processes have been developed that allow the formation of grooves with intentional under-etching of the mask, e.g. photo resist. In a succeeding metal evaporation step this very same mask obstructs the deposition of meta

New concepts in silicon solar cell design require dry processing technologies. For this reason two reactive ion etching (RIE) processes have been developed: one for surface cleaning and one for the removal of phosphorous glass (PSG). However, damage

The use of hydrogen for passivation of multicrystalline silicon in solar cell technology is described. Three kinds of hydrogen incorporation into mc-Si solar cells have been evaluated: hydrogen diffusion out of a SiN-layer (SiN:H), low-energy hydroge

The introduction of selective emitters underneath the front contacts of solar cells can considerably increase the cell efficiency. Thus, cost-effective fabrication methods for this process step would help to reduce the cost per W p of silicon solar c

Conference Record of the Twenty-Eighth IEEE Photovoltaic Specialists Conference - 2000 (Cat. No.00CH37036).
New processing schemes for fabricating the rear contact pattern of the PERC-structure (passivated emitter and rear cell) are demonstrated. Both, thermally-grown silicon oxide (SiO/sub 2/) and plasma-deposited silicon nitride (SiN/sub x/) are used as
