The influence of the transparent conducting oxide (TCO) topography was studied on the performance of a silicon oxide intermediate reflector layer (IRL) in a-Si/μc-Si tandem cells, both experimentally and by 3-D optical simulations. Therefore, cells

This paper addresses the achievements and challenges in a-Si:H/µc-Si:H tandem solar cell technology including production aspects. As an example we show figures of the module production at Masdar PV, with module conversion efficiencies reaching 10%.

LiMo(3)Se(3) is a highly anisotropic solid comprised of a regular pattern of quasi-1-D wire-like structures. Solutions of LiMo(3)Se(3) deposited on substrates and TEM grids reveal the presence of two-dimensional network morphologies. High resolution

We report on recent developments of a-Si:H/a-Si:H based thin film solar cells on Gen8.5 module area. The initial efficiency of 5.7 m² modules and 1.4 m² sub-modules has been increased from 5% to 8% using standard floatline, low-cost glass substrate

We report a model of nanowire (NW) mechanics that describes force vs displacement curves over the entire elastic range for diverse wire systems. Due to the clamped-wire measurement configuration, the force response in the linear elastic regime can be

To exploit the novel size-dependent mechanical properties of nanowires, it is necessary for one to develop strategies to control the strength and toughness of these materials. Here, we report on the mechanical properties of silver nanowires with a un

Nanowires and nanotubes have attracted much interest as potential building blocks for nanotechnology. This interest can be traced to the novel structural and electronic properties of these nanomaterials. Here we describe a study that measures the ele

Surface texturing in thin-film solar cells provides a promising way of addressing the loss components due to reflection and poor light absorption inside the cells. In this work, we study the reflection suppression performance of different submicron-s

The direct depth measurement of structures with aspect ratios between 1 and 4 in the arrays of memory cells represents a major challenge for inline metrology. For 75 nm and larger technology nodes these measurements are carried out using inline AFM u

A comparison of four different methods to make electrical contact to both 100nm gold nanowires and 50nm multiwall carbon nanotubes is given. The techniques are compared in terms of the success yield, contact resistance, complexity of the fabrication
