Development and Implementation of In-line Characterization Methods for Roll-to-Roll Production of Thin-Film Solar Modules

This report emphasizes the importance of implementing quality control methods in the production machines at HyET Solar for assessing the quality of deposited materials. The focus is on two key steps: the deposition of the front transparent conductive oxide (TCO) layer and the deposition of silicon layers. Models were developed to characterize...

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...

Hydrogenated Indium Oxide (IO:H) by Plasma Enhanced Spatial Atomic layer deposition for thin film PV application

Hydrogenated Indium Oxide (IOH) has been recognized as a high performance transparent conductive oxide (TCO) due to its excellent mobility (>100 cm2/Vs) and high transparency (>90%) in the visible and near infrared region of the spectrum. Plasma enhanced spatial atomic layer deposition (PESALD), a new type of deposition process developed...
