2014 MRS Spring Meeting


A7.06 - III-V Nanowires for Next Generation Solar Cells


Apr 24, 2014 10:30am ‐ Apr 24, 2014 11:00am

Description

There is an increasing interest in finding novel concepts for increasing the efficiency-to-cost ratio in solar cell devices. Among the different possibilities, semiconductor nanowires have shown to provide various paths towards this goal.

In this talk, I will discuss different aspects in considering semiconductor nanowires for next generation photovoltaics:

  1. Increased device freedom for optimizing the carrier extraction and light absorption.
  2. A self-concentrating effect which provides the potential to surpass the Shockley-Queisser limit [1].
  3. Three-dimensional-heterostructure design in up-conversion strategies [2].
