Renewable Energy Technologies for Sustainable Development

cells.In a similar way microbial fuel cells (MFC) can be used to generate electrical power from municipal waste sludge, which is shown in a research article.It was found that the maximum output voltage was affected by the nanoscale zerovalent iron during the start-up process.Perovskite solar-cells (PSCs) have attracted extensive interests owing to their high energy conversion efficiency and facile solution processability for fabrication.As part of this special issue, recent progress of PSCs is reviewed with an emphasis on low-cost manufacturing and extending long-term service life.Artificial photosynthesis (AP) for renewable energy conversion and storage can achieve ultimate long-term sustainability.An Essay looks at the developments of integrating AP with an analysis on the advantages and disadvantages of this technology.It has been an absolute joy and pleasure to edit this special issue.I would like to thank the editor of Advanced Sustainable System, Dr. Till von Graberg, for coordinating the special issue and handling all papers.I would like to sincerely thank all authors for their high quality contributions to this special issues.
