Influence of local surface defects on the minority-carrier lifetime of passivating-contact solar cells

Christophe Ballif, Mathieu Gérard Boccard, Jan Haschke, Jean Cattin

Unlocking the full potential of passivating contacts, increasingly popular in the silicon solar cell industry, requires determining the minority carrier lifetime. Minor passivation drops limit the functioning of solar cells; however, they are not detected ...

Development of an inorganic cesium carbonate-based electron transport material for a 17% power conversion efficiency perovskite solar cell device

Mohammad Khaja Nazeeruddin, Iwan Zimmermann, Brahim Aissa

A low-temperature solution process technique is employed to develop an inorganic cesium carbonate (Cs2CO3) as an electron transport material for inorganic-organic hybrid double cation (FAPbI(3))(0.85)(MAPbBr(3))(0.15) perovskite solar cells, as an alternat ...

Monitoring radiation damage in the LHCb Tracker

Elena Graverini, Mark Tobin, Preema Rennee Pais, Pavol Stefko

This paper presents the techniques used to monitor radiation damage in the LHCb Tracker Turicensis during the LHC Runs 1 and 2. Bulk leakage currents in the silicon sensors were monitored continuously, while the full depletion voltages of the sensors were ...

Study on the signal-to-noise ratio of Brillouin optical-time domain analyzers

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Zhisheng Yang, Sheng Wang

The signal-to-noise ratio (SNR) of Brillouin optical time-domain analyzers (BOTDA) is modelled and experimentally validated, using direct detection with and without the use of optical pre-amplification. The behavior of SNR as a function of the Brillouin ga ...

Low-temperature carbon-based electrodes in perovskite solar cells

Ulf Anders Hagfeldt, Bowen Yang, Jaekeun Lim, Dmitry Bogachuk, Konrad Wojciechowski

Carbon-based electrodes have been widely applied in perovskite solar cells (PSCs) because of their chemical inertness and compatibility with up-scalable techniques, signifying their solid potential for mass-production. The material scarcity and complexity ...

Cu2O photocathodes with band-tail states assisted hole transport for standalone solar water splitting

Michael Graetzel, Kevin Sivula, Yuhang Liu, Ulf Anders Hagfeldt, Liang Yao, Dan Ren, Linfeng Pan

Photoelectrochemical water splitting provides a promising solution for harvesting and storing solar energy. As the best-performing oxide photocathode, the Cu2O photocathode holds the performance rivaling that of many photovoltaic semiconductor-based photoc ...

CuSCN as Hole Transport Material with 3D/2D Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Iwan Zimmermann

We report stable perovskite solar cells having 3D/2D perovskite absorber layers and CuSCN as an inorganic hole transporting material (HTM). (Phenylethyl)ammonium (PEA) and [(4-fluorophenyl)ethyl]ammonium (FPEA) have been chosen as 2D cations, creating thin ...
