Increasing the efficiency of crystalline silicon (c-Si) solar cells requires the reduction of both bulk and interface recombination. Even if bulk recombination is almost suppressed, the symmetry of the crystal lattice is disturbed at the surface and hence, ...
The electronic properties of hydrogenated amorphous silicon (a-Si:H) relax following stretched exponentials. This phenomenon was explained in the past by dispersive hydrogen diffusion, or by retrapping included hydrogen motion. In this letter, the authors ...
A novel mechanical structure design with reduced deflection offset is reported. This design offers a batch processing solution to a well-known problem in the fabrication of very thin crystalline silicon structures, that is initial bending due to anchoring ...
The constant energy consumption and world-wide demography expansion add to the potential risks of ecological and human disaster associated with global warming. This makes it a necessity to develop renewable energy technologies such as photovoltaic energy. ...
Production volume of PV modules increases at > 35% per year, but one is yet far from making a global impact on energy supply. One of the obstacles is given by the present high production costs of PV modules. A possibility to reduce costs are thin-film PV m ...
A novel mechanical structure design with reduced deflection offset is reported. This design offers a batch processing solution to a well-known problem in the fabrication of very thin crystalline silicon structures, that is initial bending due to anchoring ...
We describe the VLSI implementation of MIMO detectors that exhibit close-to optimum error-rate performance, but still achieve high throughput at low silicon area. In particular algorithms and VLSI architectures for sphere decoding (SD) and K-best detection ...

Recent developments are going towards miniaturized devices and structures. Besides advanced photolithography techniques, complementary patterning methods are evolving. Among them is the nanostencil technique. Schematic overview of setup in operation: the s ...
In microcrystalline hydrogenated silicon (μc-Si:H), the drift mobility dependencies of holes on electric field and temperature have been measured by using a method of equilibrium charge extraction by linearly increasing voltage. At room temperature the est ...
Three-layer structures of thick (>5 μm) films of nanosized titanium dioxide, zirconium dioxide, and carbon have been screen-printed on a semi-prodn. level for use in photosensitized photovoltaic devices. The films have been characterized using SEM, x-ray d ...
