Dopant-Free Pyrene-Based Hole Transporting Material Enables Efficient and Stable Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Paul Joseph Dyson, Farzaneh Fadaei Tirani, Zhaofu Fei, Bin Ding, Yong Ding, Keith Gregory Brooks

Dopant-free hole transporting materials (HTMs) is significant to the stability of perovskite solar cells (PSCs). Here, we developed a novel star-shape arylamine HTM, termed Py-DB, with a pyrene core and carbon-carbon double bonds as the bridge units. Compa ...

Carbon nanotube film replacing silver in high-efficiency solid-state dye solar cells employing polymer hole conductor

Ulf Anders Hagfeldt, Nikolaos Vlachopoulos

A semitransparent, flexible single-walled carbon nanotube (SWCNT) film was efficiently used in place of evaporated silver as the counter electrode of a poly(3,4-ethylenedioxythiophene) polymer-based solid-state dye solar cell (SSDSC): the solar-to-electric ...

Chemical Vapor Deposition Repair of Graphene Oxide: A Route to Highly Conductive Graphene Monolayers

Klaus Kern, Marko Burghard

Highly conductive chemically derived graphene can be synthesized using an efficient two-step method starting from graphene oxide. The key strategy involves the use of a CVD process to heal defects contained within the monolayers, which imparts a two order ...

Enhanced thermal stability and spin-lattice relaxation rate of N@C-60 inside carbon nanotubes

László Forró, Bálint Náfrádi

We studied the temperature stability of the endohedral fullerene molecule N@C-60 inside single-wall carbon nanotubes using electron-spin-resonance spectroscopy. We found that the nitrogen escapes at higher temperatures in the encapsulated material as compa ...

Influence of ion bombardment on microcrystalline silicon material quality and solar cell performances

Christophe Ballif, Andrea Feltrin, Grégory Bugnon, Fanny Sculati-Meillaud

Microcrystalline hydrogenated silicon growth with VHF-PECVD was examined in an industrial type parallel plate KAITM reactor. The influence of pressure on material quality was studied in single junction solar cells. Solar cells with their intrinsic layer pr ...

Overview of co-deposition and fuel inventory in castellated divertor structures at JET

Richard Pitts

The main focus of this work is fuel retention in plasma components of the JET water-cooled Mk-I divertors operated with small tiles, first with carbon fibre composite (CFC) and then with castellated beryllium. Until recently these have been the only large- ...

Nanofibres de carbone sur filtre métallique comme support catalytique structuré

Pascal Tribolet

The main objectives of this work are 2-fold : The development of a novel type of composite material based on carbon nanofibers supported on sintered metal fibers filters (CNF/SMF) and to explore the use of this material as a catalytic support for a model r ...
