Materials for energy

F

Earth-abundant next generation materials for solar energy - IV

Climate change and the growing demand on energy are motivating research in sustainable energy production. The sun provides free and abundant energy and its capture by photovoltaics or in production of solar fuel a highly active area of materials research. The use of earth abundant materials is critical for sustainability.

Scope:

This symposium will address fundamental and applied aspects of materials suitable for earth abundant solar energy production. Relevant technologies include photovoltaics, thermal solar, water splitting and solar fuel production. Recent developments in both experimental and theoretical/computational approaches will be addressed making this symposium an ideal platform for researchers working on all stages of development of earth abundant and newly emerging materials for thin film solar materials.

Photovoltaics has continued to be a highly active and growing field, and we anticipate over half of the abstract submissions will relate to PV. The focus will be on development of materials and devices outside of those already well developed industrially, i.e. materials other than Si, CdTe and CIGS. Absorber materials will include but will not be limited to CZTS and related multinary compounds, hybrid organic/inorganic perovskites (including lead-free, perovskite-inspired materials), SnS, Cu2O, FeS2, Zn3P2, ZnSnN2, ZnSnP2, Cu2S, Cu3N, WSe2 etc.

As well as materials that form the components of PV cells, including of the absorber layer but also buffers and TCO layers, the symposium will target other forms of solar energy capture including, water splitting photoelectrodes, electrocatalysts for oxygen and hydrogen evolution.

Novel experimental techniques for synthesis of all the relevant layers are of interest combined with characterization methods for defects, surfaces and interfaces, charge carrier dynamics and doping strategies. Theoretical calculations of interest include high throughput methods for new materials, defect calculations combined with the search for new defect tolerant materials and numerical device simulations to better understand the current limitations in device performance of the emerging devices.

  • Halide solar cells: perovskites and perovskite-inspired materials
  • Nitride, sulfide and phosphide photovoltaic absorbers
