... slower than paste-deposited films. Photoactivity of the films decreased with silver deposition due to the nature of the organic compounds. The rate constants were calculated to be between 2 × 10 − 1 and 6 × 10 − 2 mg m 2 ∕ kJ for organic compounds, and 6 × 10 − 2 and 6 × 10 − 3 for total organic carbon...
