Fabricating IBC solar cells with screen printed dopant pastes requires high print resolution in order to align the interdigitated doped pattern. In high-volume solar cell production a screen printable paste must maintain high fidelity between the printed feature and the intended feature size defined by the screen opening.
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.
This rheological property is well established for metal pastes used in solar cell applications38,39. Paste A has a shear viscosity of ηpaste-A = (111.9 ± 5.0) Pa s at a shear rate of ̇γ = 101 s−1 and a decreased shear viscosity of ηpaste-A = (5.6 ± 0.1) Pa s at a shear rate of ̇γ = 103 s−1.
We report results on the development of a cost-effective all-screen-printed interdigitated back contact (IBC) solar cell process. The rear side interdigitated doping pattern is achieved using screen printed n-type and p-type dopant pastes, and thermal drive-in.
Here, a low-temperature curing Ag paste was applied onto SHJ solar cell by parallel dispensing. The SEM image is taken out of ref.12. Ag pastes, an understanding of the paste’s inner state during micro-extrusion is needed to solve the limitations of applicable process velocities and line electrode widths.
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.
