Toward Eco-friendly and Stable Perovskite Materials for Photovoltaics

Eco-friendly Blocks by Blended Materials

In spite of broad improvements in construction technology, cement is still stayed as binding material for construction purposes. Cement industries are the main sources for the contribution of carbon dioxide (co2) into the atmosphere. So, there is a need to use new materials as binders (green binders) in substitute for cement, which leads to reducing the production of cement. In this study, fly ...

Eco-friendly high-performance silicide thermoelectric materials

Silicide-based thermoelectrics are examples of cost-efficient and environmentally friendly new energy materials, which can be used for power-generation applications in the range of 500–800 K. We review the research focusing on the exploration of n-typeMg2IV-based solid solutions (IV= Si, Ge and Sn) and summarize the most prominent discoveries achieved so far in their studies. Owing to their sup...

Perovskite photovoltaics: Slow recombination unveiled.

news & views neighbouring spins are pointing in opposite directions) as a proximity layer is a new approach in the context of magnetic topological insulators. Antiferromagnets and 'artificial antiferromagnets' (engineered heterostructures in which the coupling between ferromagnetic layers can be tuned) are widely used in magnetic memory applications. One of their advantages is the absence of a ...

Band Gap Tuning via Lattice Contraction and Octahedral Tilting in Perovskite Materials for Photovoltaics.

Tin and lead iodide perovskite semiconductors of the composition AMX3, where M is a metal and X is a halide, are leading candidates for high efficiency low cost tandem photovoltaics, in part because they have band gaps that can be tuned over a wide range by compositional substitution. We experimentally identify two competing mechanisms through which the A-site cation influences the band gap of ...
