Debye length defined as:
The scale over which mobile charge carriers screen out electric fields
As LD increases so does charge separation.
Increase in relative permittivity with increasing concentration of barium titanate with phosphonic acid ligand.
Increase in photo-conductivity in light and dark conditions for polymers with and without “novel” material.
Improve the number of incident photons captured by the solar cell
Improve the number and type of excitons produced from incident photons
Increase the exciton diffusion length
Increase the number and quality of interfacial boundariesFuture Work in EMTERC
Active polymer matrix
