A synthetic approach that improves absorber layers in perovskite solar cells could help them achieve their full potential and draw closer to the performance of leading gallium arsenide devices.
Solar cells that rely on perovskite thin films to capture sunlight are the fastest growing photovoltaic technology. Cheaper and easier to manufacture and incorporate into devices than conventional semiconductors, lead halide perovskites also effectively absorb visible light and display long charge carrier diffusion lengths an indicator of their ability to maintain light-induced electrons and holes separation and facilitate charge transport.
Performance of solar cells hinges on absorber materials with a high-quality crystal structure and a narrow bandgap to maximize sunlight harvesting. This optimal bandgap range spans energies of 1.1 to 1.4 eV, which corresponds to near-infrared wavelengths.

Copper nanomaterials with a cubic shape so perfect that they form neatly aligned stacks when brought together have been created by researchers at KAUST. The cuboid copper nanoclusters, developed by rational design, are a new member of an exotic nanomaterial family that has shown many promising properties but has remained very hard to make. Copper nanomaterials are a class of materials that exhibit useful properties for the fields of photoluminescence and catalysis, says Ren-Wu Huang, a postdoc in Osman Bakr s lab, who led the research. There is great interest in synthesizing new copper nanomaterials to understand how their structure influences their function.
