Application

PT1 Platinum Paste can be used in applications that require a highly transparent layer with high electrocatalytic activity.

PT1 Platinum Paste is oil-based and formulated to be applied using a screen printer; providing films with excellent uniformity; performance and reproducibility; and can be used for DSSC polot production.

After drying; this paste must be fired at or above 420°C. This results in uniformly distributed platinum nanoclusters; providing good transparency and high catalytic activity for the electrochemical reduction of I3- to I-.

Articles

Dye-sensitized solar cells (DSCs) are 3rd generation solar cells combining the promise of high efficiency with low production costs.

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

Professors Tokito and Takeda share design principles and optimization protocols for organic electronic devices, focusing on flexibility and low cost.

Progress in solution-processed functional materials leads to thin-film optoelectronic devices for industrial and consumer electronics.

Questions

1–2 of 2 Questions  
  1. Can the paste be thinned using solvent? If so, which? Also, will be paste become solid if cured underneath the 420degC temperature? And would it adhere to a polymer substrate? Thanks!

    1 answer
    1. This platinum paste has initially been developed as a screen printing paste to obtain a highly conductive and “catalytic” amount of platinum when printed on a transparent substrate (glass, plastics), while allowing the substrates to maintain their transparency after deposition and annealing. The concentration of platinum is therefore quite low (<1%), and the screen printed layer is usually quite thin. Any changes to the product would be for the researcher to experiment with. This paste must be fired at or above 420°C and any modifications made to the product does void the performance guarantee.

  2. Does it work as a conductive paste? Do you have the resistivity of the paste?

    1 answer
    1. Unfortunately, Product 791512 has not been tested for its properties in terms of conductivity or resistivity. Rather, it was developed for its catalytic properties.
