What is Conducting polymers and applications?
Conducting polymers are organic polymers that conduct electricity due to conjugated π-electron systems, enabling applications in devices such as light-emitting diodes, solar cells, and supercapacitors.
The field encompasses 125,156 works with applications demonstrated in polymer light-emitting diodes, photovoltaic cells, and electrode materials. Burroughes et al. (1990) introduced light-emitting diodes based on conjugated polymers, achieving electroluminescence in thin films. Yu et al. (1995) enhanced polymer photovoltaic cell efficiencies through internal donor-acceptor heterojunctions using MEH-PPV and C60 blends.
