Case Study

Improvement of Performance and Stability in Perovskite Solar Cells Through Cellulose Acetate Butyrate

Xiao, Bo, et al. Journal of Energy Chemistry 76 (2023): 259-265.

This research explored the use of cellulose acetate butyrate (CAB), an eco-friendly and affordable organic polymer, to enhance the efficiency and environmental durability of planar perovskite solar cells (PSCs).
Methodology: CAB was introduced into the perovskite layer through a solution-based processing method to passivate grain boundaries and interface defects. The resulting perovskite films were characterized using structural, optical, and electronic measurements. Device performance was evaluated through current-density voltage measurements under simulated AM 1.5G illumination. Stability tests were conducted under accelerated aging conditions including high humidity (35-65% RH), elevated temperature (65°C), and continuous light soaking.
Key Findings:
· CAB passivation led to high-quality perovskite films with markedly reduced defect density and nearly tenfold increased carrier lifetime.
· The optimal CAB-treated device reached a power conversion efficiency of 21.5%, while the untreated control achieved 18.2%.
· CAB-formed bonds between its functional groups (ester and hydroxyl) and perovskite components (Pb, I, organic cations) enhanced structural and environmental stability.
· The treated devices retained over 90% of their initial efficiency after 3300 hours at 35% RH and after 500 hours under combined heat (65°C), humidity (65% RH), or light soaking conditions.

Cellulose Acetate Butyrate Used in Reverse Osmosis Membranes for Water Desalination

Abdellah Ali, Salah F., et al. Cellulose 27.16 (2020): 9525-9543.

This study combined cellulose acetate propionate (CAP) and cellulose acetate butyrate (CAB) with cellulose acetate (CA) to produce reverse osmosis (RO) membranes. The effects of different combinations on hydrophobicity, salt rejection, and permeate flux were investigated.
Methodology: Pristine and blended RO membranes were fabricated using the phase inversion technique. The casting solution consisted of dioxane (27 wt%), acetone (13.5 wt%), acetic acid (5 wt%), and methanol (10.7 wt%) as solvents and non-solvent. CAB, CA, and CAP were used as membrane materials in varying compositions. The solution was cast on glass plates or polyester fabric supports at a controlled thickness, followed by immersion in an ice-water bath, annealing, and storage in deionized water.
Key Findings:
· The contact angle increased from 56° for pure CA membranes to 74° for CAB membranes, indicating enhanced hydrophobicity.
· Pristine CAB membranes demonstrated a salt rejection rate of 96.8% with a permeate flow of 1.07 L/m2·h.
· Blended membranes, such as CA/0.5 wt% CAB supported on nonwoven polyester fabric, achieved a salt rejection of 91.4% with a permeate flow of 6.05 L/m2·h.
· The incorporation of CAB improved mechanical strength and structural integrity while maintaining competitive desalination performance.
