A research group led by Associate Prof. Simone Fabiano at the Laboratory of Organic Electronics, Linköping University, has created an organic material with superb conductivity that doesn't need to be doped.
The group achieved this by mixing two polymers with different properties.
To increase the conductivity of polymers, and in this way obtain higher efficiency in organic solar cells, light-emitting diodes and other bioelectronic applications, researchers have until now doped the material with various substances.
Typically, this is done by either removing an electron or donating it to the semiconductor material with a dopant molecule, a strategy that increases the number of charges and thereby the conductivity of the material.
"We normally dope our organic polymers to improve their conductivity and device performance. The process is stable for a while, but the material degenerates and the substances we use as doping agents can eventually leach out," said Fabiano,
