Optical modeling and characterization of transparent conductive oxides: Implementation of thin film solar cells

To make silicon thin film solar cells attractive to the market, their efficiencies should reach the efficiencies of the dominant crystalline silicon solar cell. Therefore the search for ways to improve the efficiency of silicon thin film solar cells continues. TCO front contact layers and back reflector layers play a significant role in the...

Complex Field Mapping of Large Direct Detector Focal Plane Arrays

Complex field mapping is a powerful tool to characterize the optical performance of astronomical instruments, and has become the standard for characterizing heterodyne array cameras. Recently, an adaptation of the heterodyne beam mapping technique was demonstrated on a single pixel of a direct detector instrument. We present a novel...

Optical characterization of photovoltaic materials and structures for thin-film solar cells based on advanced texturization

Advanced texturization is a promising approach to increase the performance of thin-film solar cells. Currently, light trapping schemes implemented in state-of-the-art devices utilize randomly textured interfaces to increase their optical performance. Periodic gratings, however, have the potential to outperform their random counterparts and are...
