1 Alwaystone Conductor Pastes for solar Cells
The Thick Film Materials Division of Uninwell International is market leader in electronic materials such as thick film pastes and materials for passive components and hybrid circuits, as well as advanced materials such as LTCC materials and photo-etchable pastes.
Due to the development of conductive pastes, this expertise can be used in the photovoltaic industry.
Uninwell® Aiwaystone™ is the brand name for products that are used to apply electrical contacts to solar cells of the first photovoltaic generation (wafer based cells).
The conductive pastes are based on silver. The Uninwell Solarcare series is cadmium-free and the printing properties are excellent. After firing, the series stands out due to its high efficiency and fill factor along with excellent line resolution. Lead-free formulations are also available.

2 Solarcare Conductor Pastes for Thin Film solar Cells
Uninwell has now introduced afeatures a new range of low temperature screen printable pastes for all major thin film PV applications enabling more cost effective manufacturing of solar cells with improved efficiency and yield.
The main purpose of the low temperature curing Ag Silver paste is for use as a front side current collector grid and bus bar to reduce the resistive losses due to the relatively low conductivity of the transparent conductive oxide (TCO) layer used in thin film PV devices.
Uninwellt® Solarcare™ lacan be used on both rigid (glass, silicon) and flexible (polyimide, polyester, stainless steel) substrates.
