Different natures of sub-gap states in 135-CIGS/112-CIGS and 112-CIGS/135-CIGS heterostructures investigated by photoluminescence technique

Journal of Physics: Conference Series, 2018
CuIn1-xGaxSe2 (112-CIGS) has been proposed as a material for high efficiency thin film solar cells with reliably applicable photovoltaic properties. Higher efficiency devices can be achieved by various surface treatments and are believed to have Cu deficiency at the surface. One of the possible techniques is to have a very thin Cu-depleted surface, e.g.

Engineering CIGS grains qualities to achieve high efficiency in ultrathin Cu(InxGa1−x)Se2 solar cells with a single-gradient band gap profile

Results in Physics, 2019
Reducing the Cu(InxGa1−x)Se2 (CIGS) thickness is an effective way to reduce the material use and increase manufacturing throughput. However, it is still a challenge to obtain high efficiency in the ultrathin CIGS solar cell.

Electronic Cigarette Vaping Did Not Enhance the Neural Process of Working Memory for Regular Cigarette Smokers

Frontiers in Human Neuroscience, 2022
BackgroundElectronic cigarettes (e-cigs) as substitute devices for regular tobacco cigarettes (r-cigs) have been increasing in recent times. We investigated neuronal substrates of vaping e-cigs and smoking r-cigs from r-cig smokers.MethodsTwenty-two r ...

Optimum Band Gap Energy of ((Ag),Cu)(InGa)Se₂ Materials for Combination with NiMo–NiO Catalysts for Thermally Integrated Solar-Driven Water Splitting Applications

Energies, 2019
Solar-driven water splitting is considered one of the promising future routes to generate fuel in a sustainable way. A carbon-free solar fuel, molecular hydrogen, can here be produced along two different but intimately related routes ...

Traces of iron impurities in copper sources can be a poison to Cu(In, Ga)Se2 solar cells

Nano Select, 2022
It has been widely accepted that the diffusion of iron from stainless steel substrates has detrimental impact on Cu(In, Ga)Se2 (CIGS) solar cell performance. However, the effect of traces of iron impurities in copper sources can be neglected all the time.

Data on lateral photocurrent along a Cu(In,Ga)Se2 thin film as a function of air exposure time

Data in Brief, 2019
Wavelength-dependent (i.e. penetration-depth-dependent) lateral photocurrent (iLP) measurement has been used to extract depth-resolved Lc profiles, where Lc is the minority carrier collection length by diffusion.

Effect of sodium diffusion on the properties of CIGS solar absorbers prepared using elemental Se in a two-step process

Scientific Reports, 2019
The influence of Na diffusion from various glass substrates during a high-temperature slenization process on the microstructure and morphology of two-step formed CIGS absorber layers is investigated. In order to minimise the CIGS absorber formation time,
