## Abstract

We derive exact analytical solution of the Shockley-Queisser (SQ) model and present all photovoltaic (PV) characteristics in compact and convenient form via the Lambert W function. We show that the SQ condition of chemical of equilibrium between photocarriers and emitted phonons leads to a new thermodynamic relation between the maximal conversion efficiency and the photo-induced chemical potential. Also, we consider kinetics of PV conversion and establish relation between the photocarrier collection time and photocarrier lifetime. We consider photonic and electronic requirements for approaching of SQ limit in semiconductor PV devices and highlight a role of photon reabsorption.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
