Ultra-Efficient Photovoltaics: Solar Concentration vs. External Photon Recycling

Prof. Eugene A. Katz,Department of Solar Energy and Environmental Physics, Swiss Inst. for Dryland Environmental and Energy Research, J. Blaustein Institutes for Desert Research, Ben-Gurion University of the Negev, Israel. 

The maximum efficiency of any solar cell (so-called Shockley-Queisser limit) can be evaluated in terms of its ability to emit light in open circuit (OC) and to quench the luminescence in short circuit (SC) [1-2]. In first part of my lecture I will
review the basic principles of ultra-high efficient phyotovoltaics as well as their experimental realization using optical
 concentration of sunlight [3] and external photon recycling [4]. At the second part of the lecture I will raise a question (and give some preliminary answers) if this strategy can be applied to emerging photovoltaic technology based on metal-halide perovskite solar cells [5].
