Gate-tunable Scanning Tunneling Microscope as a tool for performing single-molecule chemistry

Shai Mangel

The atomic level understanding and control of the electron transport has important advantages for many applications, such as molecular electronics, solar cells and sensors. The target of my Ph.D. work is to investigate electronic and chemical properties of ...

EPFL2019

Scattering particles constitute a key light trapping solution for thin film photovoltaics where either the particles are embedded in the light absorbing layer or a thick layer of them is used as a reflector. Here we introduce a monolayer of wavelength-scal ...

Design of periodic nano- and macro-scale textures for high-performance thin-film multi-junction solar cells

Christophe Ballif, Franz-Josef Haug, Etienne Antoine Julien Moulin

Surface textures in thin-film silicon multi-junction solar cells play an important role in gaining the photocurrent of the devices. In this paper, a design of the textures is carried out for the case of amorphous silicon/micro-crystalline silicon (a-Si:H/m ...

Cobalt and/or copper complexes for use as hole transport layer dopants to improve optoelectronic or photoelectrochemical devices

Michael Graetzel, Mohammad Khaja Nazeeruddin, Shaik Mohammed Zakeeruddin, Fabrizio Giordano, Ulf Anders Hagfeldt, Marina Freitag, Julian Burschka

This invention discloses a new class of dopants that allows easy tuning of the chem., phys., optical and/or electronic properties of the doping agent in order to carefully adapt it to the desired application, such as org. solar cells or solid state dye-sen ...

U.S. Pat. Appl. Publ. (2016),2016

Spherical dielectric particles, nanofibers, and nanorods have been widely used as embedded scattering objects in nanostructured thin film solar cells. Here we propose micron-scale rod-like dielectric particles as a more effective alternative to the spheric ...

Using the Stark effect to understand charge generation in organic solar cells

Jacques-Edouard Moser, Natalie Renuka Banerji, Jelissa Risse, Natalie Stingelin

We have used a femtosecond-resolved spectroscopic technique based on the Stark effect (electromodulated differential absorption) in order to investigate free charge generation and charge drift in solar cell devices of neat conjugated polymer pBTTT and in i ...

Polymer Brush Guided Formation of Conformal, Plasmonic Nanoparticle-Based Electrodes for Microwire Solar Cells

Harm-Anton Klok, Anna Fontcuberta i Morral, Anna Dalmau Mallorquí, Caroline Sugnaux

This report explores the use of sacrificial thin polymer films prepared by surface-initiated polymerization as a template for the fabrication of highly conformal metal nanoparticle solar cell electrodes. As a first proof-of-principle, the use of this metho ...

NIR sensitive organic dyes for tandem solar cells and transparent photodiodes

Hui Zhang

Due to advantages such as mechanical flexibility, light weight and the prospect to use low-cost roll-to-roll manufacturing processes, organic semiconductors have been widely investi-gated in many application areas as alternatives for their inorganic counte ...

EPFL2015

Thin-film silicon solar cells are often deposited on textured ZnO substrates. The solar-cell performance is strongly correlated to the substrate morphology, as this morphology determines light scattering, defective-region formation, and crystalline growth ...
