A design and manufacturing method for an interdigitated backside contact photovoltaic (PV) solar cell less than 100 μm thick are disclosed. A porous silicon layer is formed on a wafer substrate. Portions of the PV cell are then formed using diffusion, epitaxy and autodoping from the substrate. All backside processing of the solar cell (junctions, passivation layer, metal contacts to the N⁺ and P⁺ regions) is performed while the thin epitaxial layer is attached to the porous layer and substrate. After backside processing, the wafer is clamped and exfoliated. The front of the PV cell is completed from the region of the wafer near the exfoliation fracture layer, with subsequent removal of the porous layer, texturing, passivation and deposition of an antireflective coating. During manufacturing, the cell is always supported by either the bulk wafer or a wafer chuck, with no processing of bare thin PV cells.

A hybrid wireless optical and radio frequency (RF) communication link utilizes parallel free-space optical and RF paths for transmitting data and control and status information. The optical link provides the primary path for the data, and the RF link provides a concurrent or backup path for the network data, as well as a reliable and primary path for the control and status information. When atmospheric conditions degrade the optical link to the point at which optical data transmission fails, the hybrid communication link switches to the RF link to maintain availability of data communications. The switch may occur automatically, based on an assessment of the quality of the optical signal communicated through the optical path.

A control approach of adjusting the input power of a power factor correction (PFC) stage so that the output voltage (DC-link) of the input AC/DC stage to an intermediate DC voltage (DC-Bus voltage) is adjusted based on the amount of power required to charge a high energy battery is disclosed. The present invention controls the input power of the PFC instead of the DC-bus voltage as is common in conventional methods. Therefore, a very fast response compared to the conventional sluggish voltage loop can be achieved. Also, having different DC-bus voltages for different output load conditions allows the DC/DC converter to work with an optimal duty cycle for a whole range of load variations.

The present invention provides microwave systems and methods for achieving better control of process and film properties by optimizing plasma containment shield shaping around an antenna. By using a containment shield, plasma generated by microwave may become more homogeneous, and the pressure inside a processing chamber may be reduced. By optimizing the shape of the containment shield, the lifetime of metastable radical species may be increased. One aspect of extending the lifetime of metastable radical species is to allow better control of chemical reaction and thus help achieve the desired film properties. For an array of antennas, the containment shield comprises a dielectric coated metal base with dividers between the antennas. The divider comprises a dielectric material or a mixture of a dielectric layer and a dielectric coated metal layer, and allows coupling among the antennas. Such a dielectric coated metal containment shield may be easier to be manufactured at lower cost than a containment shield comprising only dielectric material such as quartz.
