A Markov Chain Approach for Defining the Fundamental Efficiency Limits of Classical and Bifacial Multi-junction Tandem Solar Cells
Muhammad A. Alam, M. Ryyan Khan
Bifacial tandem cells promise to reduce three fundamental losses (above-bandgap, below bandgap, and the uncollected light between panels) inherent in classical single junction PV s…

Fundamentals of PV Efficiency: Limits for Light Absorption
M. Ryyan Khan, Xufeng Wang, Muhammad A. Alam
A simple thermodynamic argument related to a (weakly absorbing) finite dielectric slab illuminated by sunlight- originally suggested by Yablonovich- leads to the conclusion that th…

Fundamentals of PV Efficiency Interpreted by a Two-Level Model
Muhammad A. Alam, M. Ryyan Khan
Elementary physics of photovoltaic energy conversion in a two-level atomic PV is considered. We explain the conditions for which the Carnot efficiency is reached and how it can be…
