Abstract
To date, because of solar energy storage coupled with nanomaterials, surface engineering has become an essentially critical method for functional electrode design. Despite years of research on nanoscale materials for energy storage, commercial batteries still make use of microscale materials for electrodes. This is due to a combination of manufacturing challenges for nanoscale materials and the reactive nature of nanoscale materials that leads to high irreversible capacities associated with solid electrolyte interphase formation. Surface texturing is a powerful tool to decouple bulk material properties from surface characteristics that often bottleneck energy storage applications of nanomaterials and has been successfully used to improve the efficiency of photo detectors and solar cells due to a reduction in reflections at the surface. Therefore, the simple wet acid surface texturing methods for green energy-silicon solar energy are reviewed with the aim to provide the vital information about the growing field in surface engineering of solar energy with environmental friendly nature.
