Light-induced degradation in multicrystalline silicon: the role of copper [PDF]

, 2016
In this contribution, we provide an insight into the light-induced degradation of multicrystalline (mc-) silicon caused by copper contamination. Particularly we analyze the degradation kinetics of intentionally contaminated B- and Ga-doped mc-Si through ...

Why Does the PV Solar Power Plant Operate Ineffectively?

Energies, 2023
Quality, reliability, and durability are the key features of photovoltaic (PV) solar system design, production, and operation. They are considered when manufacturing every cell and designing the entire system.

Energy performance of commercial c-Si PV modules in accordance with IEC 61853-1, -2 and impact on the annual specific yield

EPJ Photovoltaics, 2023
As energy yields of photovoltaic modules are highly related to local climate and ambient conditions, it is necessary to assess the energy-yield performance of PV modules under various operating conditions.

Amplitude response and singularity behavior of circadian clock to external stimuli

npj Systems Biology and Applications, 2023
Amplitude changes caused by environmental cues are universal in the circadian clock and associated with various diseases. Singularity behavior, characterized by the disruption of circadian rhythms due to critical stimuli, has been observed across various

An Injectable, Self-Expanding Hemostatic Foam for Field-Compatible Postpartum Hemorrhage Management. [PDF]

Adv Sci (Weinh)
Postpartum hemorrhage is the leading cause of maternal death worldwide, yet many treatments are hard to use outside well‐equipped hospitals. This work introduces an easy‐to‐use device that rapidly delivers a degradable foam into the uterus. The foam stops bleeding through pressure and clotting support, offering a practical option for low‐resource ...

Characterization of a liquid-core waveguide cell for studying the chemistry of light-induced degradation [PDF]

, 2021
Many organic compounds undergo changes under the influence of light. This might be beneficial in, for example, water purification, but undesirable when cultural-heritage objects fade or when food ingredients (e.g., vitamins) degrade.

Cu gettering by phosphorus-doped emitters in p-type silicon: Effect on light-induced degradation

AIP Advances, 2018
The presence of copper (Cu) contamination is known to cause relevant light-induced degradation (Cu-LID) effects in p-type silicon. Due to its high diffusivity, Cu is generally regarded as a relatively benign impurity, which can be readily relocated ...

ASi-Sii-defect Model of Light-induced Degradation in Silicon [PDF]

, 2014
The observation of light-induced degradation (LID) in indium-doped silicon has led to the idea of an ASi-Sii-defect responsible for LID. Generation of silicon self interstitials (Sii) leads, in consequence of the ASi-Sii-defect model, to an enhancement ...

Characterization of light induced degradation in crystalline silicon [PDF]

, 2013
Light induced degradation is an unfortunate characteristic of a very commonly used silicon material for solar cells: boron-doped Czochralski silicon. The degradation is attributed to a recombination center that is activated by excess charge carriers, i.e.

Effect of Different Regeneration Processes on LID Degradation Mechanisms in B-doped p-type c-Si PERC Solar Cells in Industrial Production

SiliconPV Conference Proceedings
Light-induced degradation (LID) and elevated temperature-induced degradation (LeTID) mechanisms negatively affect the performance of p-type Cz-Si-based solar cells.
