1. A method for measuring a photoluminescence response from an object, the method comprising the steps of:
(i) exposing the object to solar irradiation to generate photoluminescence from the object; and
(ii) measuring a signal from the object in a spectral band selected such that at least 20% of the measured signal comprises photoluminescence generated from the object by the solar irradiation,
wherein the object comprises a photovoltaic module comprising a plurality of silicon photovoltaic cells.
