Article Synopsis
- - Chemical bath deposited (CBD) SnO is crucial for high-efficiency perovskite solar cells, but its traditional deposition process is slow, taking 3-4 hours.
- - A new method has been developed that uses a concentrated Sn source and Sb doping, reducing deposition time to just 5 minutes while maintaining 95% efficiency.
- - The CBD SnO substrates can be recycled, and refurbished solar cells retain approximately 98% of their initial efficiency after being recycled three times.

Thermal-conversion properties of cellulose, hemi-cellulose and holo-cellulose derived from woody biomass were studied using TG-FTIR, and also compared to those of avicel cellulose and xylan. 3-D diffusion model was applied to calculate the kinetic parameters of thermal-conversion reaction of biomass materials, such as the activation energy, pre-exponential factors, etc, which showed good regression results. With the analysis of three-dimensional IR spectra of gas products, featured peaks of HzO, CO, CO2, CH4, and oxygenates were obviously observed where showing up with the maximum weight-loss rate in DTG curves.
