Wheeler2 1National Renewable Energy Laboratory, 15013 Denver W Pkwy, Golden, CO 80401 2University of Wisconsin – Stout, 712 Broadway St S, Menomonie, WI 54751 Abstract There are a number of technical and socio-economic factors converging to position photovoltaic

Efficiency Potential of Photovoltaic Materials and Devices

A consistent mathematical approach is presented that connects the Shockley-Queisser (SQ) theory to the analysis of real-world devices. We demonstrate that the external photovoltaic quantum efficiency Q e PV of a solar cell results from a distribution of SQ-type band-gap energies and how this distribution is derived from experimental data. This leads us to the

value for the analysis of the device performance. For a variety of solar-cell devices, we show that the combination of QPV e and electroluminescence measurements allows for a detailed loss analysis that is fully compatible with the principle of detailed balance.

Twin Scientists Advance Understanding of PV Windows

Now, only one twin remains at NREL, but their collaboration continues. The dynamic duo co-authored a newly published article in ACS Energy Letters, titled "Detailed Balance Analysis of Photovoltaic Windows." The sole authors are listed as Lance M. Wheeler and Vincent M. Wheeler—they also share a middle name, Michael.

Detailed Balance Analysis

The photons of interest for solar energy have wavelengths close to or below one micron. Hence, these textures scatter light according to geometric-optical phenomena, namely refraction and reflection from the facets of the textures. Luque, A., Mellor, A.V. (2015). Detailed Balance Analysis. In: Photon Absorption Models in Nanostructured

Detailed Balance Analysis of Photovoltaic Windows

Rational design of PV windows is of paramount importance to realize their impact. In this work, we provide an analysis on the theoretical performance of PV windows using a detailed balance model to understand the complex design space of power conversion efficiency, visible light transmittance, solar heat gain coefficient, and color.

Detailed Balance

Detailed balance provides a technique to calculate the maximum efficiency of photovoltaic devices. Originally the method was proposed by Shockley and Queisser in 1961 1. An extended version was published in 1984 by Tiedje et al. 2. Detailed balance in its simplest and most common implementation makes several fundamental assumptions:
