Coordination Chemistry as a Universal Strategy for a Controlled Perovskite Crystallization

The most efficient and stable perovskite solar cells (PSCs) are made from a complex mixture of precursors. Typically, to then form a thin film, an extreme oversaturation of the perovskite precursor is initiated to trigger nucleation sites, e.g., by vacuum, ...

Frontiers, opportunities, and challenges in perovskite solar cells: A critical review

Mohammad Khaja Nazeeruddin

The breakthrough discovery of organic-inorganic hybrid perovskite materials for converting solar energy into electrical energy has revolutionized the third generation photovoltaic devices. Within less than half a decade of rigorous research and development ...

Effect of a halogen-based precursor on dopant incorporation in 3C-SiC film epitaxy

Marco Negri

Silicon carbide thin films were synthesised by vapour phase epitaxy technique on silicon substrates using silane and propane as precursors. Methyltrichlorosilane (MTS) was added, and nitrogen was used as dopant precursor. Samples with different doping conc ...

A combinatorial chemical beam vapour deposition approach to tune the electrical conductivity of Nb:TiO2 films via Si co-doping

Paul Muralt, Silviu Cosmin Sandu, Giacomo Benvenuti, Estelle Wagner, Scott Harada

Chemical beam vapour deposition (CBVD) is a thin film deposition technique operated under high vacuum conditions in which film growth occurs through the thermally activated chemical decomposition of precursor molecules at the substrate surface. This techni ...

Solvation quantities from a COSMO-RS equation of state

Vassily Hatzimanikatis

This work focuses on the extension of the successful COSMO-RS model of mixtures into an equation-of-state model of fluids and its application for the estimation of solvation/hydration quantities of a variety of chemical substances. These quantities include ...

Speciation of aqueous tellurium(IV) in hydrothermal solutions and vapors, and the role of oxidized tellurium species in Te transport and gold deposition

Lothar Helm, Pascal Grundler

Despite the close association between tellurium (Te) and gold (Au) in many epithermal, orogenic, and intrusion-related hydrothermal ore deposits, the hydrothermal chemistry of Te remains poorly understood. We studied the protonation/ deprotonation and stru ...

High-performance tandem silicon solar cells on F:SnO2

Christophe Ballif, Sylvain Nicolay, Laura Ding

High-performance transparent conducting oxides (TCOs) have significance for optimising PV performance. The efficiency of the resulting solar cells is dependent particularly on achieving high light scattering, low resistivity and low absorption (via low fre ...

Comparison of amorphous silicon absorber materials: Light-induced degradation and solar cell efficiency

Christophe Ballif, Franz-Josef Haug, Matthieu Despeisse, Grégory Bugnon, Jan-Willem Alexander Schüttauf, Michael Elias Stückelberger

Several amorphous silicon (a-Si:H) deposition conditions have been reported to produce films that degrade least under light soaking when incorporated into a-Si:H solar cells. However, a systematic comparison of these a-Si:H materials has never been present ...

Gold-Free GaAs Nanowire Synthesis and Optical Properties

Anna Fontcuberta i Morral

To date, the use of gold for the synthesis of nanowires has proven to be nearly impossible to circumvent, regardless of the potential negative effects on the nanowires physical properties. In this paper, the synthesis of gallium arsenide nanowires without ...

Microcrystalline silicon solar cells: effect of substrate temperature on cracks and their role in post-oxidation

Christophe Ballif

Microcrystalline silicon (mc-Si:H) cells can reach efficiencies up to typically 10% and are usually incorporated in tandem micromorph devices. When cells are grown on rough substrates, ‘‘cracks’’ can appear in the mc-Si:H layers. Previous works have demons ...
