Blocking the Charge Recombination with Diiodide Radicals by TiO2 Compact Layer in Dye-Sensitized Solar Cells

Nikolaos Vlachopoulos, Ulf Anders Hagfeldt, Kazuteru Nonomura

The addition of a compact titanium dioxide (TiO2) layer between the fluorine-doped tin oxide (FTO) coated glass substrate and the mesoporous TiO2 layer in the dye-sensitized solar cell (DSC) based on the iodide/triiodide redox couple (I-/I-3(-)) is known t ...

A peri-Xanthenoxanthene Centered Columnar-Stacking Organic Semiconductor for Efficient, Photothermally Stable Perovskite Solar Cells

Shaik Mohammed Zakeeruddin, Peng Wang, Yang Li, Rui Zhu

Modulating the structure and property of hole-transporting organic semiconductors is of paramount importance for high-efficiency and stable perovskite solar cells (PSCs). This work reports a low-cost peri-xanthenoxanthene based small-molecule P1, which is ...

Strategic advantages of reactive polyiodide melts for scalable perovskite photovoltaics

Michael Graetzel, Andrey Petrov

Despite tremendous progress in efficiency and stability, perovskite solar cells are still facing the challenge of upscaling. Here we present unique advantages of reactive polyiodide melts for solvent- and adduct-free reactionary fabrication of perovskite f ...

First-principles calculations of iodine-related point defects in CsPbI3

Joachim Maier, Alessandro Senocrate

We present here first principles hybrid functional calculations of the atomic and electronic structure of several iodine-related point defects in CsPbI3, a material relevant for photovoltaic applications. We show that the presence of neutral interstitial I ...

Diverging surface reactions at TiO2- or ZnO-based photoanodes in dye-sensitized solar cells

Nikolaos Vlachopoulos, Ulf Anders Hagfeldt, Kazuteru Nonomura, Gunther Wittstock

Fast recombination of electrons from semiconductors with the oxidized redox species in the electrolyte represents a major bottleneck in the improvement of ZnO-based dye-sensitized solar cells (DSSCs). While processes at the semiconductor-electrolyte interf ...

Universal Oxide Shell Growth Enables in Situ Structural Studies of Perovskite Nanocrystals during the Anion Exchange Reaction

Raffaella Buonsanti, Anna Loiudice, Seryio Saris, Michal Stanislaw Strach

The ability to tune thin oxide coatings by wet-chemistry is desirable for many applications, yet it remains a key synthetic challenge. In this work, we introduce a general colloidal atomic layer deposition (c-ALD) synthesis to grow an alumina shell with tu ...

Towards Oxide Electronics: a Roadmap

Ulf Anders Hagfeldt, Francisco Sanchez, Mauro Fanciulli, Monica Marcela Lira Cantu, Brahim Dkhil

At the end of a rush lasting over half a century, in which CMOS technology has been experiencing a constant and breathtaking increase of device speed and density, Moore's law is approaching the insurmountable barrier given by the ultimate atomic nature of ...

Gallium Nitride as Transparent Electron-Selective Contact in Silicon Heterojunction Solar Cells

Christophe Ballif, Mathieu Gérard Boccard, Angela Nicole Fioretti, Tzu-Chin Chang Chien, Yashi Xiao

Carrier-selective, passivating contacts have allowed silicon heterojunction (SHJ) cells to reach recordbreaking efficiencies particularly in all-back-contacted designs. However, two-side-contacted SHJ cell efficiency has been limited due in part to parasit ...

Majority Charge Carrier Transport in Particle-based Photoelectrodes

Sophia Haussener, Yannick Kenneth Gaudy

The inter-particle charge transfer of particle-based photoelectrodes was investigated using a particle-based LaTiO2N photoelectrode as model system. The thickness-dependent front- to back-side illumination photocurrent ratio was measured and compared to th ...

Annealing of Silicon Heterojunction Solar Cells: Interplay of Solar Cell and Indium Tin Oxide Properties

Christophe Ballif, Raphaël François Lemerle, Mathieu Gérard Boccard, Jan Haschke, Brahim Aissa

In this paper, we report the evolution of silicon heterojunction solar cell properties focusing, in particular, on the indium tin oxide (ITO) layers upon consecutive thermal annealing. We find that the charge carrier density
