Application:

Production of pigmented solar cells


Certified ByTrust

Product Introduction:

This paste is used to make a layer of TiO2 (titanium dioxide) with the ability to reflect and respread light. The paste contains rutile TiO2 particles of several hundreds of nanometers with a coating of SiO2. This type of scattering layer has great reflection power; on the other hand, it does not cause a drop in the electrical properties of the cell. Due to its insulating properties, this paste can make separator layers in monolithic cells. The paste contains submicron particles of titania with a rutile phase (average size 400 nm) and a nanometer shell of silica (thickness 70 nm) as a reflective layer with the ability to reflect nearly one hundred percent in all visible wavelengths. The concentration of titania in the final product is 28 weight percent.

The production process of rutile titanium dioxide transparent paste with a silicon dioxide shell is complex. The reason for this complexity is the need to control several parameters in its production process. These parameters include: creating a strategy to obtain particles with a rutile crystal phase and with an average size of 400 nm, forming a silicon dioxide shell with a nanometer thickness on titania, as

well as non-agglomeration of particles with a high percentage of solids (28 weight percent) and long-term stability (more than three years).
