Microscopy & Microanalysis 2023

We are very excited to be attending Microscopy & Microanalysis 2023 meeting in Minneapolis MN, July 23 – 27, 2023.  Come visit us at booth #1038

Hands on Micromanipulator Tutorials

BTS will be giving two workshops on our Micro Support micromanipulator – one on basic micromanipulator use and a second on microplastics handling and detection. Sign up at our booth!

Precise Micro Sampling With a Benchtop Micromanipulator Tutorial
Tuesday 7/25/2023 – 5:45 pm at booth #1038

Microscopic sample preparation can be difficult to near impossible as structures become smaller.  We will show how a benchtop micromanipulator can be used to probe, scrape, cut, and isolate materials on a surface.  The system can also be configured to allow these microsampling operations inside a glovebox.

Attendees will be able to work directly with the system and are encouraged to bring samples they would like to try out during the Workshop.

Microplastics Handling and Detection Workshop
Wednesday 7/26/2023- 5:45 pm at booth #1038

Microplastics represent a new class of environmental contaminant that has been increasing over time throughout the world. We will demonstrate imaging and micro sampling using the Micro Support Axis Pro micromanipulator on microplastics samples.  We will also speak about Soar Optics class of comprehensive microplastics detection systems and where we see the future of microplastics detection.

The micro manipulator is perfect for isolating micro plastics.

MobileGuard Gas Detection

Teco Peoples Gas hits the road in one of their new methane detection vehicles. These vehicles are going to be game changers for Peoples Gas. The Ford Escapes are outfitted with MobileGuard, a cutting-edge, laser-based analyzer that uses special software and windspeed calculations to pinpoint natural gas leaks by locating methane emissions. The sensitive sensors can detect with ultra-high precision – parts per billion, as compared with our handheld leak detection equipment which detects parts per million. That means they will detect methane emissions that you can’t smell and would otherwise go unnoticed. And, the system is smart enough to know if the methane detected is from natural gas or other sources like biogas from sewers.

Installation Highlights

We are glad to share the news about the implementation of Barnett Technical Services installation of a significant engineering project.

The company has received the request and later an order from the Chevron energy corporation’s research center to develop an IR Fourier Spectrometer for controlling the chemical reaction in the on-line process.

The Barnet Technical Services Team along with Ostec engineers have implemented developing the industrial version on the basis of the standard air based FTIR spectrometer IROS 05. To transform the research device into an industrial unit it was necessary to develop a sealed device case filled with dry nitrogen under extra pressure, to select and replace a typical IR detector with an MCT detector with Peltier cooling, to develop a cooling system and temperature stabilization for ensure the lowest possible noise level inside the device, as well as specialized software for obtaining data and its subsequent processing.

AttoLight’s CHRONOS Time-Resolved Cathodoluminescence for characterizing CIGS SOLAR CELL

Attolight’s Chronos time-resolved cathodoluminescence tool was recently used to characterize an advanced Cu(In,Ga)S2 device that showed an efficiency of 15.2% from a H2S-free, Cd-free, and KCN-free process. significantly limited mainly due to photovoltage (Voc) losses in the bulk and at the interfaces. Here, via a combination of photoluminescence, cathodoluminescence, electrical measurements, and ab initio modeling, we address the bulk and interface losses to improve ∼1.6-eV-band-gap (Eg) Cu(In,Ga)S2. The optoelectronic quality of the absorber improves upon reducing the [Cu]/[Ga+In] (CGI) ratio, as manifested by the suppression of deep defects, higher quasi-Fermi level splitting (QFLS), improved charge-carrier lifetime, and higher Voc. We identify antisite CuIn/CuGa as a major performance-limiting deep defect by comparing the formation energies of various intrinsic defects. Interface recombination is suppressed using a Zn(O,S) buffer layer in Cu-poor devices, which leads to the activation energy of recombination equal to the Eg. We demonstrate an efficiency of 15.2% with Voc of 902 mV from a H2S-free, Cd-free, and KCN-free process.

Context & scale

Cu(In,Ga)S2 is a high-potential material for its usage in tandem solar cells; however, its power conversion efficiency has remained limited so far. High bulk recombination losses and interface losses both account for the performance limitation. In this work, we adopt a holistic approach to address both bulk and interface recombination losses. We show that bulk recombination losses can be substantially suppressed by controlling the Cu deficiency in the material. From theoretical calculations, we argue that Cu deficiency reduces the antisite defects that are probably the most detrimental defects. Additionally, we effectively passivate the interface through the usage of Zn(O,S) buffer layer, thereby minimizing the losses at the interface. This leads to a solar cell device performance of over 15% from 1.6-eV-band-gap Cu(In,Ga)S2 from a completely non-toxic process. The path to further performance improvement is discussed to increase the viability of Cu(In,Ga)S2 toward tandem application.
