Title: High Performance Microscale Silicon Photovoltaics

Enabled with Nanophotonic Light Management and Spectral Upconversion

Speaker: Prof. Jongseung Yoon (University of Southern California)

Host of a Seminar: Prof. Byoungwoo Kang

Abstract:

 

Unconventional approaches to exploit silicon can create novel engineering designs, device

functionalities, and cost structures, each with significant practical values in next generation

photovoltaics. In particular, ultrathin forms of single-crystalline silicon derived from waferbased

source materials represent an excellent materials building block for high-efficiency,

low cost solar cells due to a number of unique advantages such as superior materials

properties, reduced materials consumption, relaxed requirements of materials purity, and

ability to form large area modules on unlimited choices of substrates. In this talk, I will give

an overview of recent advances in materials design and fabrication pathways for ultrathin

microscale single-crystalline silicon solar cells and heterogeneously integrated module

designs, with a special emphasis on strategies for maximizing absorption of longer

wavelength photons to improve the performance of printed optically thin silicon solar cells

and their flexible modules, including nanoscale photon management enabled with

integrated programmable surface nanostructures, as well as enhanced luminescence of

spectral upconversion under non-concentrated solar illumination through plasmonically

engineered nanostructured reflectors
