Influence of N-type μc-SiOx:H intermediate reflector and top cell material properties on the electrical performance of “micromorph” tandem solar cells

AIP Advances, 2018
Amorphous silicon (a-Si:H) / micro-crystalline silicon (μc-Si:H), "micromorph" tandem solar cells have been investigated using a detailed electrical - optical model. Although such a tandem has good light absorption over the entire visible spectrum, the a-

Three-dimensional flow instability in a lid-driven isosceles triangular cavity [PDF]

, 2011
Linear three-dimensional modal instability of steady laminar two-dimensional states developing in a lid-driven cavity of isosceles triangular cross-section is investigated theoretically and experimentally for the case in which the equal sides form a ...

Investigation on the dependence of degradation rate on hole concentration during boron-oxygen related light-induced degradation in crystalline silicon

AIP Advances, 2018
Boron-oxygen related light-induced degradation (BO-LID) of effective charge carrier lifetime is one of the major problems for photovoltaics based on oxygen-rich boron-doped wafer substrates.

Formation kinetics of copper-related light-induced degradation in crystalline silicon [PDF]

, 2014
Light-induced degradation (LID) is a deleterious effect in crystalline silicon, which is considered to originate from recombination-active boron-oxygen complexes and/or copper-related defects.

Study on the Electrical Injection Regeneration of Industrialized B-Doped Czochralski Silicon PERC Solar Cells

International Journal of Photoenergy, 2019
In this paper, 156 mm×156 mm boron-doped Czochralski silicon (Cz-Si) wafers were fabricated into PERC solar cells by using the industrial standard process; then, the as-prepared PERC solar cells were treated by the regeneration process using electrical ...

FastNano Liquid: An Automated Platform for Small‐Angle X‐ray Scattering‐Based Materials Discovery

Advanced Engineering Materials, EarlyView.
We present FastNano Liquid, an automated small‐ and wide‐angle X‐ray scattering platform for the combined synthesis and characterization of (nano)materials. The platform is coupled to varied reactor workflows for both in situ studies of reaction kinetics and ex situ screening of synthesis conditions to support machine learning‐guided exploration ...

Room-temperature method for minimizing light-induced degradation in crystalline silicon [PDF]

, 2012
Although light-induced degradation (LID) in crystalline silicon is attributed to the formation of boron-oxygen recombination centers, copper contamination of silicon has recently been observed to result in similar degradation.

LEDs for the Implementation of Advanced Hydrogenation Using Hydrogen Charge-State Control

International Journal of Photoenergy, 2018
Light-induced degradation (LID) of p-type Cz solar cells has plagued the industry for many decades. However, in recent years, new techniques for solving this LID have been developed, with hydrogen passivation of the boron-oxygen defects appearing to be ...

2D Skeletal Muscle Thin Film Actuators Enhance Efficiency of Biohybrid Robots

Advanced Functional Materials, EarlyView.
2D skeletal muscle thin film actuators generate millinewton‐scale forces and millimeter‐scale strokes while remaining functional for over 30 days. Their force density is 20‐fold higher than 3D skeletal muscle actuators, enabling multi‐fin robots with tunable speed and multidirectional steering.
