Low-Temperature Screen-Printed Metallization for the Scale-Up of Two-Terminal Perovskite-Silicon Tandems

Christophe Ballif, Antonin Faes, Jacques Levrat, Gabriel Christmann, Bertrand Yves Paul Paviet-Salomon, Arnaud Walter, Nicolas Badel, Adriana Paracchino, Matthieu Despeisse, Sylvain Nicolay

Tandem photovoltaic devices based on perovskite and crystalline silicon (PK/c-Si) absorbers have the potential to push commercial silicon single junction devices beyond their current efficiency limit. However, their scale-up to industrially relevant sizes ...

I-2 vapor-induced degradation of formamidinium lead iodide based perovskite solar cells under heat-light soaking conditions

Christophe Ballif, Quentin Thomas Jeangros, Adriana Paracchino, Sylvain Nicolay, Jérémie Werner, Fan Fu, Peter Joseph Fiala, Léo Duchêne

Over the last years, the operational stability of perovskite solar cells has been significantly improved by compositional engineering, interface modification, and improved encapsulation techniques. However, irreversible degradation is still ubiquitously ob ...

Synthesis and Characterization of High-Photoactivity Electrodeposited Cu2O solar absorber by photoelectrochemistry and ultrafast spectroscopy

Michael Graetzel, Jacques-Edouard Moser, Adriana Paracchino, Jan Cornelius Brauer

We present a systematic study on the effects of electrodeposition parameters on the photoelectrochemical properties of Cu2O. The influence of deposition variables (temperature, pH, and deposition current density) on conductivity has been widely explored in ...

Cu-based p-type Oxide Photocathodes for Solar Hydrogen Production : a Study on Photoelectrochemical Performance and Stability

Adriana Paracchino

The actualization of a hydrogen economy requires cost-effective and environmentally benign solutions to hydrogen production. Chemical energy in the form of hydrogen is more interesting than electricity to satisfy our ever-increasing energy demand because i ...

Highly active oxide photocathode for photoelectrochemical water reduction

Michael Graetzel, Kevin Sivula, Vincent Laporte, Adriana Paracchino

A clean and efficient way to overcome the limited supply of fossil fuels and the greenhouse effect is the production of hydrogen fuel from sunlight and water through the semiconductor/water junction of a photoelectrochemical cell, where energy collection a ...
