Research proposalElena KhonThe development and optimizing the performance of high efficient prototype solar cells
I propose work that will target:
Schematics of photovoltaic device hetero-epitaxial NC/oxide nano-composites
Electronic energy level of each material layer in a NC-sensitized solar cell comprising a solid hole conductor. Vertical bars represent size-dependent band edge energies for several semiconductor NCs.
The increasing of the efficiency of photovoltaic device achieved through understanding of growth kinetics of each nanocrystal/oxide system, the development of large-scale and well-controlled synthesis of durable nanostructures, and optimization of device performance
