General description

Titania paste, active opaque is a precursor for titania that has anatase particles and larger sized anatase scatter particles, used to form a white coating on the fluorine doped tin oxide glass (FTO) substrate. It is used in a variety of electrochemical devices to improve electron mobility and power efficiency.

Application

Titania paste has a hierarchical pore structure which allows non-agglomerated loading on nanomaterials for the fabrication of dye sensitized solar cells with higher light absorption.
Use Active Opaque Titania Paste in applications that do not require transparency.
The dispersed scattering particles in Active Opaque Titania Paste formulation lead to enhanced DSC performance through the large surface/volume ratio of the sintered film.
Active Opaque Titania Paste has a blend of active anatase particles (~20nm) and larger anatase scatter particles (up to 450nm).
After drying; this paste must be fired at or above 500°C. This results in an opaque sintered layer with film thickness of 7-8μm for one printed layer and ~15μm for two layers; when using a 48T mesh.
This paste exhibits optimal rheological properties that provide good surface uniformity and contain organic binders specially formulated to provide versatile porosity suitable for a range of dye/electrolyte systems.
Storage: Store in the dark at 20°C

Organic and Hybrid Electronics in Optical Analytical Applications

Professor Shinar (Iowa State University, USA) summarizes the developments of a variety of sensor configurations based on organic and hybrid electronics, as low-cost, disposable, non-invasive, wearable bioelectronics for healthcare.

Inverted Organic Photovoltaic Devices Using Zinc Oxide Nanocomposites as Electron Transporting Layer Materials

Organic photovoltaics (OPVs) represent a low-cost, lightweight, and scalable alternative to conventional solar cells. While significant progress has been made in the development of conventional bulk heterojunction cells, new approaches are required to achieve the performance and stability necessary to enable commercially successful OPVs.

Understanding and Successfully Applying Materials for Dye-Sensitized Solar Cells

While dye sensitization as the basis for color photography has been accepted for a very long time,1 attempts to use this principle for the conversion of solar light to electricity generally had resulted only in very low photocurrents, below 100 nA/cm
