Researchers at Linköping University, Sweden, have developed a stable high-conductivity polymer ink. The advance paves the way for innovative printed electronics with high energy efficiency. The results have been published in
Nature Communications.
Electrically conducting polymers have made possible the development of flexible and lightweight electronic components such as organic biosensors, solar cells, light-emitting diodes, transistors, and batteries.
The electrical properties of the conducting polymers can be tuned using a method known as doping . In this method, various dopant molecules are added to the polymer to change its properties. Depending on the dopant, the doped polymer can conduct electricity by the motion of either negatively
Study Discovers How Energy is Lost During Singlet Fission in Solar Cells

Solar energy is considered one of the most significant eco-friendly and fossil-free sustainable sources of electricity. The existing silicon-based solar cells use only around 33% of the energy in sunlight and transform it into electricity.

The reason is the packets of light, or photons, present in the sun’s beams possess energy that is either too little to be absorbed by the solar cell, or too high, such that part of the energy is released as waste heat. This optimum theoretical efficiency is called the Shockley-Queisser limit.
