Simplified fabrication process for high-efficiency solar cells

A team of EPFL and CSEM researchers in Neuchâtel presents in Nature Energy a new astonishing method of creating crystalline solar cells with electrical contacts at the rear, suppressing all shadowing at the front. Thanks to the new inexpensive approach, the fabrication process is strongly simplified with efficiencies in the laboratory already surpassing 23%.

In the quest for more efficient crystalline silicon solar cells with low manufacturing costs, one of the most promising approach is to bring all electrical contacts at the back of the device. This suppresses all shadowing at the front, increasing the current and the efficiency. This approach generally requires several delicate processing steps, because well-defined narrow negative and positive contact lines need to be created, which will then collect the electrons (negative charges) and holes (positive charges). This requires usually several steps of masking of photolithography to create the alternated positive (+) and negative (-) areas.

Drone-deliverable Gamma Detectors

GLOBall system is a mapping tool based on gamma detection systems that can be easily deployed and have a fast reconstruction map of the investigated zone. If the positioning of the detectors is done using unmanned vehicles, such as drones, this will reduce the dose exposure for the in field operators from possible radiological hazards.


The equipment is based on a set of gamma detectors. Each spherical device embeds a radiological detector and an encrypted communication system in a waterproof, shockproof shell the size of a tennis ball. They are equipped with a localization system like (GPS, or embedded pseudolites for indoor localization), a data encryption system and a communication protocol (LoRA or WiFi) to  send data to the control station.

LHCb Just Discovered New System of Five Particles

🔊 March 16, 2017 - CERN announced an exceptional new discovery that was made by the LHCb, which unveiled five new states all at once.

In a paper released, the LHCb collaboration announced the discovery of a new system of five particles all in a single analysis. The exceptionality of this discovery is that observing five new states all at once is a rather unique event.

The particles were found to be excited states – a particle state that has a higher energy than the absolute minimum configuration (or ground state) – of a particle called "Omega-c-zero", Ωc0. This Ωc0 is a baryon, a particle with three quarks, containing two “strange” and one “charm” quark.
 
The team notes that this revelation improves our understanding of quantum theory in general and, most notably, gives us new clues about the earliest moments of our universe.

Searching for cavities in the Teotihuacan Pyramid of the Sun using cosmic muons

Abstract:
The Pyramid of the Sun, at Teotihuacan, Mexico, is being searched for possible hidden chambers, by means of muon attenuation measurements inside the pyramids volume. The muon tracker is located in a tunnel, running below the base and ending close to the symmetry axis of the monument. This study presents a brief description of the experimental technique and data analysis, as well as a comparison of the first year preliminary experimental results with physics simulations using GEANT4
 
Introduction
The use of cosmic muons to measure inhomogeneities in large volumes is a rapidly growing field. A classical example of this was the experiment carried out by Luis Alvarez et al. [1] who measured the attenuation of cosmic muons in the mass of the Keops Pyramid, in Giza, Egypt, while searching for hidden empty chambers. Although this technique has been applied to other practical problems, few archeological monuments present the necessary conditions to carry out a muon attenuation inspection of its volume. Among those exceptions is in the Mexican Pyramid of the Sun at Teotihuacan, hereafter referred to as Pyramid of the Sun. In a previous presentation [2] in this conference series, we described a project aimed at solving important archaeological questions concerning the Sun at Teotihuacan, using muon attenuation. Here we present an update on this project, which began its data-taking few months ago, including important experimental aspects, and details of the corresponding GEANT 4 Monte Carlo [3] simulations which are compared with our first experimental image.

The LHC is restarting

The LHC, last among all of CERN’s accelerators, is resuming operation with beam while this issue goes to press. The year-end technical stop (YETS) started on 14 December 2015. During the 11 weeks of scheduled maintenance activities, several interventions have taken place in all of the accelerators and beamlines. They included the maintenance of the cryogenic system at several points; the replacement of 18 magnets in the Super Proton Synchrotron (SPS); an extensive campaign to identify and remove thousands of obsolete cables; the replacement of the LHC beam absorbers for injection (TDIs) that are used to absorb the SPS beam if a problem occurs, providing vital protection for the LHC; and 12 LHC collimators have been dismantled and reinstalled after modification of the vacuum chambers, which restricted their movement.

ORNL process could be white lightning to electronics industry

OAK RIDGE, Tenn., Dec. 1, 2015 – A new era of electronics and even quantum devices could be ushered in with the fabrication of a virtually perfect single layer of “white graphene,” according to researchers at the Department of Energy’s Oak Ridge National Laboratory.
 
The material, technically known as hexagonal boron nitride, features better transparency than its sister, graphene, is chemically inert, or non-reactive, and atomically smooth. It also features high mechanical strength and thermal conductivity. Unlike graphene, however, it is an insulator instead of a conductor of electricity, making it useful as a substrate and the foundation for the electronics in cell phones, laptops, tablets and many other devices.
 
“Imagine batteries, capacitors, solar cells, video screens and fuel cells as thin as a piece of paper,” said ORNL’s Yijing Stehle, postdoctoral associate and lead author of a paper published in Chemistry of Materials. She and colleagues are also working on a graphene hexagonal boron 2-D capacitor and fuel cell prototype that are not only “super thin” but also transparent.
 
With their recipe for white graphene, ORNL researchers hope to unleash the full potential of graphene, which has not delivered performance consistent with its theoretical value. With white graphene as a substrate, researchers believe they can help solve the problem while further reducing the thickness and increasing the flexibility of electronic devices.

Applications for the CryoLab cryocooler

Measurements at cryogenic temperatures were never this easy!

We recently launched a new line of plug-n-play desktop cryocoolers for applications requiring cooling of small samples to 90 K or further down to 75 K (i.e. SQUIDs).


http://www.xtronix.ch/cryolab.htm

 
Known as CryoLab, by Kryoz Technologies of Holland, the LN2-free low-temperature analysis cooling systems allow for  characterisation measurements from room temperature down to cryogenics in a fully automated manner. Doing measurements doesn’t require any experience or know-how on cryogenics, vacuum technology or thermodynamics from the user.

Time Measurements with CAEN Waveform Digitizers

In this new Application Note we focus our attention on the techniques for time measurement using waveform Digitizer. It describes the algorithms typically used for these measurements and the performances obtained in some benchmark tests using different acquistion setup. This note shows that Digitizers are capable to measure time stamps with higher accuracy (few ps resolution) compared to commercial analog solution composed by CFD and TDC modules.
 
Traditional analog devices as the Constant Fraction Discriminators (CFDs) and Time to Digital Converters (TDCs) can be very competitive in terms of channel density and cost. Highly segmented detectors are therefore often read out by analog devices featuring custom made specification to guarantee a perfect match with the experimental requirements. However the possible requirement of simultaneous measurement of energy and time poses the practical issue of complex device connections.

In some applications the implementation of a digitizer for time measurements is profitable or even necessary:
  • Applications that require an excellent timing resolution of the whole chain, of the order of few ps
  • Simultaneous acquisition of time and energy information
  • Online walk correction with integrated charge or amplitude
  • Bursts of very close pulses (e.g. Free Electron Lasers)
