In consequence, the polymer in an organic vehicle for low-temperature curable paste fulfils two tasks: 1) it adjusts the viscosity of the binder, which acts as a screen-printing medium; and 2) it facilitates the adhesion between the metal particles of the paste, as well as the adhesion to the surface of the wafer.
In this paper an investigation of material concepts for new low-temperature contact pastes for HJT solar cell preparation has been reported. Screen-printable pastes, which are curable at 150–200°C, can be prepared using suitable polymer– solvent combinations.
Today’s paste systems pose difficulties in handling during processing, especially with regard to the storage conditions. In the study reported in this paper, new metallization pastes for HJT solar cells are examined.
Ag particles distribute very uniformly in the paste. We think such uniform distribution is very beneficial not only for the coalescence growth of Ag particles, but also for the removal of the organic solvents during the sintering process. Fig. 9.
How to get excellent electrical performance for low-temperature Ag paste was studied. The paste should be made of nano-sized silver particles. The binder resin content in the paste should be low. The organic solvents with low boiling point are easy burnt out at low temperature.
The electrical performance of the new paste is similar to (or even better than) that of currently available reference metallization pastes, while a significantly easier handling and processing behaviour is observed. Using the contemporary generations of new pastes with bimodal silver mixture, the sheet resistance is decreased to 2.7mΩ/sq.

In this solar cell, the doped semiconductor layers of the emitter and the passivation layer are generated by vaporization of amor-phous silicon. The amorphous Si layers only survive a maximum temperature of 200 °C. Thus, silver pastes capable of being cured at 200 °C were developed for front-side metallization (Figure 1).
