Abstract

An arrangement includes a solar cell and a covering, wherein the covering covers the solar cell, at least on the side that is intended to be exposed to electromagnetic radiation of the sun. The covering has an electrochromic layer. The arrangement also has a control unit for controlling the electrochromic layer. The control unit is designed to control the transmittance of the electrochromic layer for electromagnetic radiation in a defined wavelength range by applying an electrical voltage to the electrochromic layer.
