A photovoltaic module comprising an elongated substrate in which at least a portion of the elongated substrate is rigid is provided. One or more solar cells are disposed on the elongated substrate and each comprise: (i) a back-electrode disposed on the elongated substrate, (ii) a semiconductor junction layer disposed on all or a portion of a surface of the back-electrode, and (iii) a transparent conductive layer, having a first refractive index, is disposed on all or a portion of a surface of the semiconductor junction. The photovoltaic module further comprises a filler material, having a second refractive index that is smaller or equal in value to the first refractive index, disposed on the transparent conductive layer of the one or more solar cells. The photovoltaic module further comprises a transparent casing disposed on the filler material thereby sealing the photovoltaic module.

A solar cell unit is provided that has a substrate having a first end and a second end, where at least a portion of the substrate is rigid and nonplanar. The solar cell unit has a plurality of photovoltaic cells linearly arranged on the substrate, including a first and second photovoltaic cell. Each photovoltaic cell in the plurality of photovoltaic cells comprises a back-electrode circumferentially disposed on the substrate, a semiconductor junction layer circumferentially disposed on the back-electrode, and a transparent conductive layer circumferentially disposed on the semiconductor junction. The transparent conductive layer of the first photovoltaic cell in the plurality of photovoltaic cells is in serial electrical communication with the back-electrode of the second photovoltaic cell in the plurality of photovoltaic cells.

Methods and apparatus to compensate for low-frequency tracking errors in motion control of a movable stage are provided. By recording tracking errors during earlier traversal of a trajectory, filtering, and applying those recorded tracking errors to subsequent traversals of the same or a similar trajectory, tracking errors of the subsequent traversals may be significantly reduced.

An apparatus and method for deflecting electron beams with high precision and high throughput. At least one electrode of a deflecting capacitor is connected to a signal source via a coaxial cable. A termination resistor is further connected to the coaxial cable and the electrode at the joint of the coaxial cable and the electrode. The termination resistor has a resistance matched to the impedance of the coaxial cable and the electrode has an impedance matched to half of the impedance of the coaxial. The deflecting capacitors of the present invention have a minimized loss of precision due to eddy current. The spacing of electrodes in the deflecting capacitors is reduced by a factor of approximately two compared to the state-the-art system.

Apparatus, systems, and methods for forming a photovoltaic cell from a common layer on a substrate are provided. A first pass is made with a first laser beam over an area on the common layer. The first pass forms a groove in the common layer. The first pass forms within the common layer a first edge and a second edge. The first edge is separated from the second edge by the groove. The groove provides a first level of electrical isolation between the first edge and the second edge. A second pass is made with a second laser beam over approximately the same area on the common layer. The second pass provides a second level of electrical isolation between the first edge and the second edge. The second level of electrical isolation is greater than the first level of electrical isolation.
