Yesterday, we harped about how scientists were able to discover the cause of efficiency in organic polymer solar cells. And now, a group of researchers have determined how some materials perform comparatively better in the realm of printable electronics. For this intricate procedure, the scientists employed powerful X-rays, which can be utilized to observe organic components at their molecular level.
The basic working of a printable electronic system involves the usage of conventional printing methods to deposit special inks containing organic conductive molecules onto the surfaces. This process results in a sort of ‘printed’ circuitry that serves the core functionality of various mechanisms such as solar cells, displays and even lighting systems.
However, when it comes to their commercial applicability, the developers and manufactures employ a cumbersome ‘trial and error’ method to observe which polymer material has higher efficiency. That is up till now; because, an international group of scientists have finally cracked the working effectiveness of such materials.
As we mentioned before, their process entailed the use of X-rays that could perceive the working state at a more definitive molecular level. In this respect, the scientists found out that the core performance always corresponded to the molecular alignment of the materials. For example, when it came to transistors, the distances of the micro alignments were directly proportional to their efficiency. And, in case of solar cells it depended upon the alignments on the surface interface.
Now, beyond just understanding the primary attributes of performance, this important ‘determining technique’ can actually lead us to develop even more advanced printable gadgetry. After all, it is always about a better perspective of a complex scope that fuels effective progression of technology.
