Abstract:
Emitter wrap-through solar cells are looked upon as one possiblecandidate for future next generation crystalline silicon solar cells. It has
the advantage of zero shadow losses, easier module interconnection with both
contacts on the back and improved collection efficiency by the backside
emitter. Although the principal concept and the possible advantages are known
for some decades, there is no commercial product using emitter wrap-through
solar cells available. To assess the potential and to discover the problems
of a possible industrial production are the aims of our project. In this
paper the developments in improving the EWT cell technology are described
both theoretically using 2D-simulations and experimentally. A special focus
was on the backside passivation of the cells which appeared to be a crucial
limiting factor for both fill factor and open-circuit voltage. 11 refs.
