Technical Note

Full-Spectrum, Angle-Resolved Reflectance and Transmittance of Optical Coatings Using the LAMBDA 1050+ UV/VIS/NIR Spectrophotometer with the ARTA Accessory

Introduction

We evaluated a 3M® visible mirror film for potential use in a new curved photovoltaic module using a LAMBDA 950 spectrophotometer with an ARTA accessory. In this application, the 3M® film must transmit near-infrared photons to the underlying silicon solar cells (where they will be converted directly to electricity) while reflecting visible photons to the focus of the module where they may be absorbed by, for example a wavelength-agnostic thermal absorber used to drive a heat engine.
