photoactive in a sentence
Examples
- Challenges of CNT for the photoactive layer include its lack of capability to form a p-n junction, due to the difficulty of doping certain segments of a CNT . ( A p-n junction creates an internal built-in potential, providing a pathway for efficient carrier separation within the photovoltaic . ) To overcome this difficulty, energy band bending has been done by the use of two electrodes of different work functions.
