Transport in semiconductors can occur under numerous different mechanisms.
The challenge in Materials Science and Engineering is to optimize the inter-connected properties in order to maximize desired functionality.
Describe materials considerations discussed by Kramer and Sargent for each of the following situations:
Absorption of light and extraction of photocharges
Electronic traps (mobility and recombination)
Interfaces with electrodes
Describe the limitations and new materials insights gained by the community from CQD-sensitized to Schottky to Depleted heterojunction devices.
Describe the roll of ligands on the electronic and device properties.
What are the major limitations in tandem cells?
These solutions may offer step-by-step problem-solving explanations or good writing examples that include modern styles of formatting and construction of bibliographies out of text citations and references. Students may use these solutions for personal skill-building and practice. Unethical use is strictly forbidden.Material consideration. Absorption of light and extraction of photocharges
Once a photon enters into a solar cell (made up of a p-n junction) it can generate a pair of electron-hole carriers. This pair will be then spatially separated by the internal electric field of the junction. Therefore to reach a contact (on a side of the solar cell) a carrier will need to travel all the depletion region length and also to diffuse then through all the neutral region length....
