Bottom Contact Metal Oxide Interface Modification Improving the Efficiency of Organic Light Emitting Diodes
Sergey M. Pozov, Apostolos Ioakeimidis, Ioannis T. Papadas +4
The performance of solution-processed organic light emitting diodes (OLEDs) is often limited by non-uniform contacts. In this work, we introduce Ni-containing solution-processed me…
Surface Treatment of Cu:NiOx Hole-Transporting Layer Using \b{eta}-Alanine for Hysteresis-Free and Thermally Stable Inverted Perovskite Solar Cells
Fedros Galatopoulos, Ioannis T. Papadas, Apostolos Ioakeimidis +2
Inverted perovskite solar cells (PSCs) using a Cu:NiOx hole transporting layer (HTL) often exhibit stability issues and in some cases J/V hysteresis. In this work, we developed a \…
Nitrobenzene as Additive to Improve Reproducibility and Degradation Resistance of Highly Efficient Methylammonium-Free Inverted Perovskite Solar Cells
Apostolos Ioakeimidis, Stelios. A. Choulis
We show that the addition of 1 % (v/v) nitrobenzene within the perovskite formulation can be used as a method to improve the power conversion efficiency and reliability performance…
Nanoparticulate Metal Oxide Top Electrode Interface Modification Improves the Thermal Stability of Inverted Perovskite Photovoltaics
Ioannis T. Papadas, Fedros Galatopoulos, Gerasimos S. Armatas +2
Solution processed γ-Fe2O3 nanoparticles via the solvothermal colloidal synthesis in conjunction with ligand-exchange method are used for interface modification of the top electrod…
Antimony doped Tin Oxide/Polyethylenimine Electron Selective Contact for reliable and light soaking-free high Performance Inverted Organic Solar Cells
Efthymios Georgiou, Ioannis T. Papadas, Ioanna Antoniou +5
We have demonstrated a high-performance low temperature solution processed electron selective contact consisting of 10 at% antimony doped tin oxide (ATO) and the neutral polymer po…
Enhanced Photovoltaic Performance of Perovskite Solar Cells by Co-Doped Spinel Nickel Cobaltite Hole Transporting Layer
Apostolos Ioakeimidis, Ioannis T. Papadas, Dimitris Tsikritzis +3
Solution combustion synthesized hole transport layer of co-doped spinel nickel cobaltite were fabricated using doctor-blading technique for planar inverted perovskite solar cells.…
