Special Issue Information

Dear Colleagues,

The perovskite crystalline system is among the most fascinating ones considering its wealth of functional properties achieved with its corner-connected anion octahedral structures. It has also played a major role in the understanding of phase transitions in solid state physics. The outstanding properties of some of its member compounds gave rise to a plethora of potential and realized applications, which are very attractive for actuators, sensors, micro and nano systems, non-volatile memories, and more recently also as catalysts and for photovoltaics. Perovskite ceramics and their applications have been studied since the Second World War, and perovskite thin films since about 35 years ago. Nonetheless, new discoveries are still being made, and our fundamental understanding is progressing with imaging tools at the nanometer scale, and atomic level simulations. We invite you to contribute to a Special Issue of the journal “Crystals” dedicated to perovskites. The aim is to combine papers on basic issues for readers starting in the field, and reviews on advanced topics giving an entry to such specializations. The introductory part will cover the rules governing the perovskite crystal structure, its chemistry and structural phase transitions in relation to basic properties. It will also include inorganic–organic hybrid perovskites, and layered perovskites. The introductory part will also include a tutorial on the synthesis of perovskite thin films treating specific issues related to the complexity of thermodynamics and chemistry. The introductory review papers will help to prepare for specific papers on advanced topics. These include, but are not limited to:

  • Ceramics and single crystal perovskites;
  • Epitaxial multilayer systems and their interfaces;
  • Dielectric and ferroelectric properties, non-linear dielectrics, tunable capacitors, giant capacities, etc.;
  • Piezoelectric properties of thin films, integration into MEMS;
  • Electro–optical properties ;
  • Magnetic properties;
  • Multiferroics;
  • Mixed electronic–ionic conductors, catalysts;
  • TEM investigations for studies on structure–property relationships;
  • Lead-free piezoelectric ceramics and thin films;
  • Role of defects and defect engineering;
  • High-Tc supraconducting films;
  • Semiconducting, and photovoltaic properties;
  • Water splitting;
  • Thermoelectric thin films;
  • Perovskite thin films for non-volatile memories.

c-Si solar cell interconnection damages from thermal cycles emanate from cumulative damage contributions from the various load steps in a typical thermal cycle. In general, a typical thermal cycle involves five thermal load steps, namely: 1st cold dwell, ramp-up, hot dwell, ramp-down, and 2nd cold dwell. To predict the contributions of each of these load steps to creep damage in soldered interconnections, each of the respective load steps needs to be profiled to accurately fit a function capable of predicting the damage contributions from a given number of thermal cycles. In this study, a field thermal cycle profile generated from in situ thermal cyclings at a test site in Kumasi, a hot humid region of sub-Saharan Africa, is used to predict damage in solar cell interconnections from accumulated creep energy density using finite element analysis (FEA). The damage was assessed for two different solder formulations, namely: Pb60Sn40 and Sn3.8Ag0.7Cu (lead-free). The results from the FEA simulations show that the cooling (ramp-down) load steps accounted for the highest accumulated creep energy density (ACED) damage in solder interconnections. The ramp-up load steps followed this closely. The cumulative contributions of the two load steps accounted for 78% and 88% of the total damage per cycle in the Pb60Sn40 and Sn3.8Ag0.7Cu solder interconnections, respectively. Furthermore, a study of the damage profiles from each of the five load steps revealed that each of the damage functions from the various load steps is a step function involving the first two thermal cycles, on one hand, and the remaining 10 thermal cycles on the other hand. The damage from the first two thermal cycles can be predicted from a logarithmic function, whereas the damage from the remaining 10 thermal cycles is predicted using six-order polynomial functions. The ACED results computed from the damage functions are in close agreement with the results from the FEA simulation. The functions generated provide useful relations for the prediction of the life (number of cycles to failure) of solder interconnections in solar cells. The systematic approach used in this study can be repeated for other test sites to generate damage functions for the prediction of the life of c-Si PV cells with SnPb and lead-free solder interconnections.
