ETDs

This collection includes most of the ASU Theses and Dissertations from 2011 to present. ASU Theses and Dissertations are available in downloadable PDF format; however, a small percentage of items are under embargo. Information about the dissertations/theses includes degree information, committee members, an abstract, supporting data or media.

In addition to the electronic theses found in the ASU Digital Repository, ASU Theses and Dissertations can be found in the ASU Library Catalog.

Dissertations and Theses granted by Arizona State University are archived and made available through a joint effort of the ASU Graduate College and the ASU Libraries. For more information or questions about this collection contact or visit the Digital Repository ETD Library Guide or contact the ASU Graduate College at gradformat@asu.edu.

Quantifying carrier selective contacts in solar cells

Description
A basic theory and terminology that comprehensively applies to all different types

of contacts in silicon solar cells has, thus far, been elusive. While the well established diode model has been applied to many of the complex contacts, the theory is not adequate to intuitively describe the characteristics of novel contacts.…

A basic theory and terminology that comprehensively applies to all different types

of contacts in silicon solar cells has, thus far, been elusive. While the well established diode model has been applied to many of the complex contacts, the theory is not adequate to intuitively describe the characteristics of novel contacts. This thesis shows that the many desirable characteristics of contacts that are discussed in the literature—carrier selectivity, passivation, and low majority carrier conductance, key among them—originate from the resistance to electrons and holes in the contact. These principles are applied to describe a few popular contact technologies in order to pave the path to envisioning novel contacts. Metrics for contact performance is introduced to quantify each of the above characteristics using the two carrier resistances. The the validity of the proposed metrics is explored using extensive PC-1D simulations.
