Contacting along the grain boundaries of mc Si solar cells

PhD thesis of Michael Radike, 1998 - ??

Abstract:

The PhD thesis of Michael Radike has the aim to develop a method to collect the charge carriers on the front side of a mc Si solar cell not as usual by a more or less dense regular grid of silver lines but to use one special feature of mc Si: there is no electrical activity along the grain boundaries and therefore the collection of the current is significantly less than in the middle of a grian. Though we have developped a PC program that is able to detect the grain boundaries of a Si wafer digitised by a flat bed scanner. After the detection the contact lines are put on the wafer not only by screen printing. We use some other technologies: Direct printing by an ink-jet printer (CANON), galvanisation of silver on silicon or photolitography. We assume a simplification of the production process of solar cells and therefore a reduction of the costs of PV devices.
