Back End Monolithic Serial Interconnection Technology for CIGS with Shunt-free Laser Scribing and Inkjet Printing

Back end interconnection technology is presented for CIGS using laser scribing and inkjet printing of dielectric material. Shunt-free laser scribing of CIGS is shown, which is essential in the back end approach for monolithic serial interconnection. Full back end interconnected mini-modules of 20x20cm2 were made and show no electrical losses...

Highly near-infrared-transparent perovskite solar cells and their application in high-efficiency 4-terminal perovskite/c-Si tandems

In this contribution the development of highefficiency planar semi-transparent perovskite solar cells (STPSCs) for tandem applications is presented. The ST-PSC absorber layer, and electron and hole transport layers were processed using spin coating. The near-infrared (NIR) transmission of the ST-PSC is optimized by improving ITO material quality...

Large area 140 cm2 perovskite solar modules made by sheet to sheet and roll to roll fabrication with 14.5% efficiency

The industrialization of perovskite solar cells (PSC) require processes to efficiently deposit the constituent layers over large areas. In this work we optimized the use of slot die coating process for both sheet-to-sheet (S2S) and roll-to-roll (R2R) manufacturing. Particular focus have been put on the control of the uniformity of perovskite...

Atmospheric Pressure Spatial ALD Layer for Ambient, Thermally and Light Stable p-i-n Planar Perovskite Solar Cells

In order to bring the organo-lead halide perovskite solar cells (PSC) towards the commercialization, the device stability needs to be drastically improved. Our approach relies on the introduction of a compact metal oxide (MeO) layer in a p-i-n planar architecture by means of atmospheric pressure spatial atomic layer deposition (s-ALD) technique....

Raman analysis of Cu(In,Ga)(Se,S)2 absorbers obtained from atmospheric selenium-sulfur annealing of electrodeposited precursors

Two step atmospheric pressure processing of Cu(In,Ga)(Se,S)2 absorbers is an industrially attractive technology to produce CIGS thin film modules. For this procedure, absorber sulfurization is required to increase the Voc and thus the efficiency of the solar cells. Raman spectroscopy was used to qualitatively identify the presence of sulfur on...

Imaging beyond aliasing

A proper spatial sampling is critical for high quality imaging. If the sampling criterion is not met, artifacts appear in the image, generally referred to as grating lobes. For inspection efficiency the width of the field of view is becoming larger leading to an increase in the number of elements and therefore transducer complexity and cost. The...

Travelling standing waves: A feasibility study

Lately, there has been significant interest in the noninvasive manipulation of particles and liquids. The reported acoustic methods rely on either the acoustic radiation force or acoustic streaming. The latter can be used in developed flows to induce fluid velocities angled to the liquid flow direction. These methods often use standing wave...

Comparison of environmental impact and energy efficiency of desalination processes by LCA

In this study two desalination technologies have been compared by means of LCA with the focus on energy supply with a variety of scenarios based on different assumptions. The studied technologies are reverse osmosis and the newly developed technology Memstill where electrical energy demand is reduced by using external thermal energy source and...

Wearable thermoelectric generators for body-powered devices

This paper presents a discussion on energy scavenging for wearable devices in conjunction with human body properties. Motivation, analysis of the relevant properties of the human body, and results of optimization of a thermopile and a thermoelectric generator for wearable and portable devices are presented. The theoretical limit for power...

Downhole multiphase metering in wells by means of soft-sensing

Multiphase flow meters are indispensable tools for achieving optimal operation and control of wells as these meters deliver real-time information about their performance. For example, multiphase flow meters located downhole can improve the production of multilateral and multizone wells by timely allocating the zone where a gas or water cone...
