Transparent Coatings- New Study In Bandpass Filters

In the field of science and technology, there have been numerous breakthroughs since the ancient times that have benefited mankind in more ways than one that have made the world a much better place to live in despite its many imperfections and shortcomings.

Over the years, these discoveries have provided us with both things to be proud of and that have caused significant financial, social and cultural losses, which is why they are held with contempt by the common people.

There is the underlining thought process that scientists have to be complimented for giving us many things to cherish for but at the same time they also had an ulterior motive of their own and simply wanted to get rich.


Leaving that argument aside, we are going to talk about an important technique that is concerned with electricity and filters which is a breakthrough to be studied and analyzed to its last detail.

Transparent coatings are the topic of discussion for today and they are also known by their broader term, which is Transparent Conducting Film (TCF) and it is a sectional part of transparent thin film covers that are useful for making electronic conductive material.

These coatings emit a very high transmission of combustible materials whose resistance is very low and sometimes downright negligible where they are of no use in various matters.

What makes it unique is that it is a part of band pass filters that assists it in handling of many electronic devices that are being tested officially by scientists because they want to ascertain further hidden components in their invention that can prove to be intellectual breakthroughs like their original counterparts.

Electronic Conduction

However, for any component to be classified as a transparent filter in electrical terminology has to prove itself a worthy competitor in this field by excelling at the norms and processes that the term signifies.

It means that they have to have a great deal of power in them so as to repel electricity backwards. In other words, they have to be resistive to current and it is this resistance technique that makes them stand out.

The resistance of electricity is quite similar to electronic conduction as both are essential properties of an electronic material that has the ability to quantify the strength of resistance towards electric currents of various degrees, both high and low.

If the resistance is low then it means that the material in question is ready to allow the electric current to surge through and if the resistance is high then the electric current cannot come anywhere near to the source.

Electric conduction is inversely proportional to electrical resistance as it determines the capability of a random material to conduct electronic processes, which in turn leads to newer discoveries in transparent coatings.

Uses of TCF

Transparent Conductive Coatings are many used as electrodes whenever there is a demand for lower resistance of electronic contact between two materials and it has to be done without blocking any light whether it is photovoltaic or light emitting diodes.

The materials in question possess a wide area of energy gaps and they are named so because their value of energy is far superior to the light that emanates from its different properties.

Due to this reason, the photons that have energy level lower than the energy gap value cannot be absorbed by these materials and as a result, the light visible to the naked eye easily passes through the barrier and emanates stronger than ever.

The coatings are used for fabrication purposes where the conduction layers are used for voltaic devices and can only be grown on a substrate piece of glass and that too only if it can provide a layered support that will allow oxide to grow on its surface.


The conductivity of transparent coatings has a low absorption level on any spectrum that gives them the technique to be a visible conductor on different devices that pertain to it but that does not mean that they cannot absorb a small part of the spectrum, which is why the efficiency level of voltaic devices is negligible.

Important points on applications:

  1. Poly conductivity is nearly 1500 sq cm
  2. Poly PSS is around 4500 sq cm
  3. Poly Dioctyl is around 1020 sq cm
