Abstract
An overview of different transparent conductors is given. In addition, atmospheric pressure CVD of ZnO resulted in conductivities below 1 mΩ cm for a temperature of 480°C, whereas at a process temperature of 200°C a value of 2 mΩ cm was obtained. Also atmospheric pressure spatial ALD was used to make conductive ZnO. Furthermore, the properties of transparent conductive oxides (TCO) can be enhanced by application of metallic grids. This way, sheet resistances of below 0.1 Ω/sq and transmittances above 85 % can be achieved. Modeling indicates that the performance of thin film cells can be enhanced by18% using a grid/TCO combination. Light scattering is a vital element of thin film solar cells and both texturization and multimaterial approaches for advanced light management such as plasmonics are discussed.
