Philip published two important papers for his cumlative PhD disertation

Written by Mukundan Thelakkat

Philip Schmode studied the concept of copolymerization as well as polar polythiophenes carrying oligoethyleneglycol substituents to obtain Ionic Electronic Mixed Conductors for applications in Organic Electrochemical Transistors. The corelation between chemical structures, volumetric capacitance, charge carrier mobility and µC* product are evluated in two papers published in Chem. Mater. (2019) and ACS AMI (2020).

Our postdoc Dr. David Heinrich left the group

Written by Mukundan Thelakkat

After a very long stay in AFUPO, David left the group end of December 2019. We wish him all the best in both private and professional lives.

SolTech seminar, "Soltech meets Industry" was organized in Nürnberg Maritim Hotel on 12.02.2020

Written by Mukundan Thelakkat

About 75 participants from SolTech and 6 representatives of industry took part in a one-day seminar at Maritim Hotel, Nürnberg

Harimohan joined the battery crew to strengthen the cathode research

Written by Mukundan Thelakkat

Mr. Harimohan Erabhoina joined AFUPO to work on new combinations of cathodes and solid polymer electrolytes, which will strengthen our battery research. Harimohan  has submitted his PhD thesis to NIT Warangal, India after working 4 years in the field of Li-S batteries and has developed many concepts to stabilize such a battery and to reduce the Li-polysulfide dissolution. He also developed high capacity anodes such as tin/graphene and silicon/graphite composites as an alternative anode to lithium metal.

Organic electrochemical transistors based on tunable conjugated copolymers

Written by Mukundan Thelakkat

In a conjugated gradient copolymer combining the hydrophilic ionic conductor PTHS and hydrophobic electronic conductor P3HT in different compositions, the water compatibility, swelling, Volume Capacitance and OECT-mobility could be varied and optimized to obtain high performance OECTS. See Chem. Mater. 2019

Sequentially co-clicked single ion Li+ conductor for batteries

Written by Mukundan Thelakkat

In an elegant approach of clicking multifunctionalities, Alexander demonstrates the utility and power of such an approach to create "custom-made" solid polymer electrolyte materials with single Li-ion conducting properties. The Poly(glycidyl propargyl ether) backbone itself offers Li-ion coordinating EO groups in addition to the OEG side chains clicked to it.

Solvent-Free Brush Polymer Electrolytes for Lithium Batteries

Written by Mukundan Thelakkat

We present a comparative study of linear and brush polymers based on PEG towards application in L-batteries as solid polymer electrolytes. See ACS Applied Energy Materials, 2019 ASAP for details

Cu(TFSI)2-Doped Hole Conductors for Efficient CH3NH3PbI3 Perovskite Solar Cells

Written by Mukundan Thelakkat

One of the challenges in n-i-p perovskite solar cells is to create stable doped (n and p) extraction layers. In this paper (ACS Applied Energy Materials 2019, ASAP) we demonstrate the use of

Cu(TFSI)2 as dopant for spiro-OMeTAD without the need of additives such Li-TFSI or tBP and air-doping

Block Copolymer Micelles for Polymer Semiconductor Nanocomposites

Written by Mukundan Thelakkat

Compartmentalized synthesis of P3HT-TiO2 nanocomposites with well-defined morphology via a micellar route was realized using the concept Self-organized Hybrids. See ACS Appl. Nano Mater. 2019, 2, 2133−2143

Ultrathin Polymeric SAMFETs with High Field-Effect Mobility

Written by Mukundan Thelakkat

We successfully grafted a monolayer of P3HT in an end-on fashion using click chemistry and realized highly efficient SAMFETs using polymeric semiconductor for the first time. For details, see ACS Applied Materials & Interfaces, 2018
