Introduction Metallization is a key process step in the fabrication of crystalline silicon solar cells. It is well known, that the composition of the metallization paste has a strong influence on the firing behaviour, contact formation and resulting efficiency of the cell.
Basic structure of crystalline silicon solar cells. The fabrication of crystalline silicon solar cells consists of three main processes, i.e., preparing a junction by diffusion, vapor deposition of an anti-reflection film, and electrode preparation).
Polycrystalline silicon solar cells may not apply to standardized processes for certain special properties. Some alternatives to the standard process have been proposed, while they have not been adopted for their relatively high cost. People are still looking for a solution, two of which are not the same as the single crystalline silicon process.
Schematic diagram of crystalline silicon solar cells. For ideal solar cells, four main assumptions are proposed: there exists no transport loss, and the body recombination is minimal. Under the mentioned assumptions, the minimum Auger recombination and good free carrier collection can be obtained with the intrinsic substrate material.
The silver paste composition for the front side has a strong influence on the firing behaviour, contact formation and resulting efficiency of the solar cell. It is state of the art that the paste glass is needed for etching the ARC silicon nitride during firing and also plays a major role for the transport of silver to the silicon surface.
However, existing industrialized silicon solar cells exhibit simple structures. The single crystalline silicon with the Czochralski method or the polycrystalline silicon with the casting method has been adopted on a large scale. Generally, these silicon materials are boron diffusion doped, with a resistivity of 0.5–0.6 Ω cm.
