Analytic expressions for the $JV$-characteristics of three types of multijunction configurations are derived. From these, expressions for the short-circuit current, open-circuit voltage, and voltage at the maximum power point are found for multiterminal devices, and for series-connected tandem stacks. For voltage-matched devices, expressions for the optimal ratio of the number of bottom cells to the number of top cells are established. Luminescent coupling is incorporated throughout the article…

Analysis of perovskite-silicon tandem solar cells using a semi-analytical model

Perovskite-silicon tandem solar cells show enhanced efficiencies due to the broader absorption of the solar spectrum. Luminescent coupling is generally observed in multi-junction solar cells, where a

Abstract. Photonic management is a key issue for the optimization of thermophotovoltaic (TPV) energy conversion systems. It is realized by selective emitters, front surface filters on TPV cells, and

Comparison of organic-inorganic p-i-n and p-n heterostructures as potential solar cell designs for use in difficult weather conditions

This paper investigates the possibility of increasing the spectral sensitivity of an organic-inorganic p-i-n-heterostructure solar cell as compared to a p-n-structure solar cell. Both p-i-n and p-n



Generalized Optoelectronic Model of Series-Connected Multijunction Solar Cells

The emission of light from each junction in a series-connected multijunction solar cell both complicates and elucidates the understanding of its performance under arbitrary conditions. Bringing

Analysis of Multijunction Solar Cell Current–Voltage Characteristics in the Presence of Luminescent Coupling

Luminescent coupling in multijunction solar cells is the phenomenon in which a junction in forward bias radiates photons that are absorbed in and converted to photocurrent by the junction beneath the

Thermodynamic efficiency limits of classical and bifacial multi-junction tandem solar cells: An analytical approach

Bifacial tandem cells promise to reduce three fundamental losses (i.e., above-bandgap, below bandgap, and the uncollected light between panels) inherent in classical single junction photovoltaic (PV)

Analytical Expressions for the Efficiency Limits of Radiatively Coupled Tandem Solar Cells

The limiting efficiency for series-connected multijunction solar cells is usually calculated from the assumption that the individual junctions are optically isolated. Here, we develop an analytical

Voltage Matching, Étendue, and Ratchet Steps in Advanced-Concept Solar Cells

Many advanced solar cell concepts propose surpassing the Shockley Queisser (SQ) limit by introducing multiple quasi-Fermi level separations that are arranged in series and/or in parallel. Exceeding
