Transparent cellulose is a research hotspot in current science. Transparent nanocellulose finds applications in energy, environment, defense, catalysis, and medicine. Sodium silicate-modified cellulose fibers were reported to be transparent. There have been various other strategies, like generating sulfate groups on nanocellulose surfaces for inducing transparency in cellulose-based materials. However, the synthesis of transparent nanospheres of cellulose with encapsu-lated sodium silicate has never been reported in the literature. Here in, for the first time, it is surmised that the cellulose nanospheres encapsulating sodium silicate will outperform any oth-er known morphologies of nanocellulose, for instance nanofibers, leading to efffective light management, especially in the perovskite-based solar cells. Sonochemistry-based approaches to synthesize cellulose nanospheres with average diameters around 50 nanometers have been demonstrated earlier. These nanospheres of cellulose encapsulated with aqueous or non-aqueous substances were used as effective nanocarriers for biomedical applications. In particu-lar, sodium silicate-encapsulated nanospheres of cellulose (SSNSC) were assumed to be a new strategic material that could act as a promising support for nanoyeast buds for accelerating the carbohydrate fermentation process via effective management of the sun’s light and heat. It is hypothesized that SSNSC, with their unique spherical morphology, will aid in the solar energy-based fermentation process by acting as an effective light management layer due to enhanced reflections within.
