Based on the fruitful results and experiences of SOPHi@Webinar  the internal  e-learning platform of 7FP-SOPHIA project has already  offered  on-line in-depth training and discussions to all SOPHIA partners, 7FP-CHEETAH is now offering "on-line"  targeted courses/seminaries open, on request, to any interested non-CHEETAH universities or  research organization, particularly students and resarchers at their early stage of their career  on:

  • Comprehensive information and transfer of knowldege on different R&D topic concering  Joint Research Activities
  • A presentation on several outstanding technical-scientific results highlighting  the potential in utilizing  the infrastructure/technique/scientific protocols and sharing common  expertise

Since January 2015 the CHEETAH Webinar Platform is exploiting the interesting results achieved by SOPHIA project  e-learning platform by  further implementing the already offered  SOPHi@Webinar facilities

CHEETAH e-learning platform has launched a series of nano-MOOCs “Learning PV at Cheetah speed” proposed and realized by Instituto de Energía Solar  Universidad Politécnica de Madrid - IES-UPM. This first course is offered by prof. Carlos del Cañizo and it is titled “Designing dopant diffusions in silicon solar cells”. This course which include presentations, key references, and exercises will help students, younger scientists and R&D engineers  to go deeper into the topic with video-presentations, suggested readings and exercises. Interested participants can follow at their own path, with an estimated student effort of around 20 hours.

This webinar introduces  1D device simulator PC1Dmod for Si solar cell simulation, including state-of-the-art physical models to extract  important emitter parameters  such as J0e and Rsh and extraction of surface recombination velocity parameters from experimental data. Simulation is used as input for larger cell structures . The second part introduces device modelling of three different solar cell architectures (IBC-HIT, Silicon heterojunction, and ZnO/Cu2O heterojunction) using Silvaco Atlas.

Solar cells based on the kesterite structure highlight for being composed of earth-abundant and nontoxic elements and for possessing high absorption coefficient with a suitable band gap, but their photovoltaic performances are decreased by low open-circuit voltage. More efforts are still needed to further increase the cell efficiency of the Cu2ZnSn(S,Se)4 solar cells to reach competitive efficiency to CdTe and CIGS solar cells. This  webinar deals with two of the more urgent issues of Cu2ZnSn(S,Se)4: the relationship among disorder, defectivity and optoelectronic properties  and the  effects of alkali bulk treatment on cell parameters.

Goal of the webinar is to introduce R2R-roll-to-roll printing processes used to manufacture arbitrary shape and decorative semitransparent organic photovoltaics panels. In addition, roll-to-roll system integration processes to manufacture functional photovoltaic systems on flexible foils and further integrate them 3D application using roll-to-roll injection moulding.

A lock-in amplifier is a type of amplifier  widely used to  extract signals with a known carrier wave from an extremely noisy signal environment. The fundamentals of the “lock-in” measurement technique for electrical characterization will be reviewed. Special emphasis will be given to a practical example of use of a real lock-in device in standard solar cell measurement (quantum efficiency).

This webinar  offered by CRES consists of two parts. The first one focusses  in the performance  characterization of PV  modules in outdoor condition according to IEC standards. The second part presents a comprehensive comparison between a poly-Si and a-Si/μ-Si thin-film tandem PV module under Long-term outdoor conditions in Greece.

An overview of electrical characterization techniques for thin film single-junction solar cells and absorbers will be given. The standard interpretation of electrical characterization techniques will be presented as well as artefacts due to the thin film device structure.

Took place on May, 03rd 2017

An overview of the materials and technologies as well as the infrastructure for PV materials research at Tallinn University of Technology (TTÜ) will be given. There is 20 years of experience in the field of research of PV materials and devices in TTÜ that has led also to a commercial implementation of the developed technologies.
