Research Area

Development of new materials for solar cells and modules (Prof. Paweł Zięba, Ph.D, D.Sc.).

 

Research is underway to develop mixed halide perovskites for use in a highly efficient and long-term stable single-junction and tandem solar cells. The aim of these studies is to find and develop an alternative cell manufacturing technology for the current one based on crystalline silicon. Moreover, the investigation is also dedicated to semiconductor metal oxides for application in solar cells in a role of passivating, anti-reflective, insulating or tunnelling layer, as well as transparent conductive layers and thin absorbers with different types of conductivity.
On the other hand, the issue of silicon nanostructures to complement the classic texture of silicon surfaces and their use as a porous substrate for perovskite layers in tandem solar cells is also being developed. The final work of modules encapsulation concerns using systems and materials other than those currently used for silicon solar cells, i.e. glass and EVA copolymer.
The study is ongoing on encapsulation processes of PV modules. The research concerns systems and materials other than those currently used for silicon cells encapsulation i.e. glass and EVA copolymer.


Interface in welds obtained with the use of explosion energy (Ph.D, D.Sc. Joanna Wojewoda-Budka, Prof. PAS)

The scientific goal of the research is the detailed characterization of the effect of the explosive welding process on the Inconel 625 / Ti Gr. 5 interface. The durable weld formed between these alloys is characterized by electron microscopy (scanning and transmission) techniques at the micro and nano scale. Because there is a strong relation between the explosive welding process and the microstructure of the joined materials close to the area of their interface, also in the case of this particular pair of materials, the presence of either thin amorphous layer or intermetallic phase(s) can be expected. The presence of brittle intermetallic phases is highly undesirable. Therefore, studies covering the detailed microstructural characteristics of the bond are aimed at developing parameters of explosive welding or the process modification that will minimize the formation of undesirable new reaction products at the interface. Additionally, the obtained welds are annealed to observe the evolution of the microstructure of joined materials near the interface zone, changes in chemical composition resulting from activated diffusion processes and the increase of intermetallic phases in the bonded zone. The annealing temperature determining the diffusion rate affects the type and amount of produced intermetallic phases or the growth of one intermetallic phase at the expense of others.
The conducted tests will allow to determine the impact of extreme pressure conditions and locally temperature on the quality of the obtained bonds, its microstructure and mechanical properties.


Development of spectral and diffraction methods in dual-beam scanning electron microscope (FIB-SEM)- (Prof. Marek Faryna, PhD, DSc)

Pioneering investigations are being performed to broaden analytical capabilities by the development of advanced analytical methods in high resolution dual beam scanning electron microscope (FIB-SEM). They are referred to energy and wave length dispersive X-ray spectrometry (EDS and WDS, respectively), as well as to electron backscatter diffraction (EBSD) technique, particularly in case of "in-situ" experiments.
Final goals to achieve:
- improvement of accuracy and precision during EDS and WDS measurements,
- improvement of spatial and effective resolution in case of orientation imaging microscopy measurements by application of transmission Kikuchi diffraction (TKD),
- development of in-situ technique based on high temperature heating stage GATAN Murano 525 designed both for phase transformation analyses and EBSD measurements at elevated temperatures.


The effect of inverting stacking faults on the reorientation of martensitic variants in Ni-Mn-Ga alloys (Associate Professor- Robert Chulist)

It is the main aim of the present research to define the role of periodic and partially periodic atom displacements called modulation and inverting stacking faults on the crystal structure and the level of twinning stress in single crystalline and polycrystalline five-layered 10M and seven-layered 14M Ni-Mn-Ga alloys. The attention is directed to the role of modulation and inverting stacking faults (a-b boundaries) which according to the recent reports have a great impact on the reorientation of martensitic variants. For this purpose high energy synchrotron radiation experiments (flat Ewald zone) and 2D detector to scan the reciprocal space in transmission geometry will be employed. Such conditions allow easy detection of additional/satellite reflections. Furthermore, a dedicated EBSD (electron backscatter diffraction) software to unveil the smallest microstructural detail will be used. This issue appears to be absolutely fundamental since the additional microstructural features affect the twinning stress in modulated phases. It will also allow to confirm or exclude the adaptive concept which remains still controversial in the literature.
