Method and apparatus for annealing micro-scale or macro solar cells that can contain lithium. Heaters, a current that is applied in forward or reverse direction, or open-circuiting the cells are used optionally with a laser or other light source to increase the temperature of the cells to perform periodic anneals to recover energy conversion efficiency lost due to environmental conditions such as radiation damage and maintain desired operational conditions. While a small amount of energy is used for heating up the small thermal mass of the micro-cells and macro cells to the desired annealing temperature, much larger amounts of additional energy is harvested with the improved efficiency of the cells. Maintaining a desired temperature for operation of cells takes very little energy owing to the small thermal mass of the cells and controlled thermal conduction of the materials in contact with the cells.

In-situ rapid annealing and operation of solar cells for extreme environment applications

A laser array () is described herein, wherein the laser array comprises semiconductor lasers () that are precisely controlled such that an optical beam output by the laser array has desired shape and direction.

Microsystems and semiconductor hybrid coherent light sources

A moldable photovoltaic module is provided. The module includes a flexible polymeric flex-circuit substrate having an electrically conductive printed wiring pattern and solder pads defined on it. Small photovoltaic cells are affixed to the flex-circuit substrate by back-surface contacts in electrical contact with the solder pads. At least one thermoformable polymeric film is joined to the flex-circuit substrate. Each said solder pad comprises a solder composition that, after an initial melt, has a melting point that lies above at least a portion of the temperature range for thermoforming the polymeric film.

Moldable photovoltaic solar cell module

Radiation detectors and methods of use thereof that produce more accurate results. A region of the radiation detector is covered by a conversion layer. A reference region is covered by a light barrier material such as a metal, and not the conversion layer. The reference region incurs less radiation damage than the region under the conversion layer. The dark current produced by the reference region can be used to more accurately calibrate the detector, provide real time normalization of the current produced by the conversion layer region, and determine when the detector has been damaged sufficiently to be replaced.

Fabrication, integration and operation of multi-function radiation detection systems

High performance single crystal silicon cells and arrays thereof are manufactured using a rapid process flow. Tunneling junctions formed in the process provide performance benefits, such as higher efficiency and a lower power temperature coefficient. The process generates a large array of interconnected high performance cells smaller than typical cells without requiring additional process steps, and simplifies integration of these coupons into the final product. The cells can have different shapes, sizes, and orientations, enabling the array to be flexible in any desired direction. Higher efficiencies and lower hot spotting under shading is achieved by connecting small low current, high voltage cells in dense series and parallel configurations. Low current cells also require much less metallization than typical solar cells and arrays.

High performance solar cells, arrays and manufacturing processes therefor

Curved, flexible arrays of radiation detectors are formed by using standard silicon semiconductor processing materials and techniques and additional functionalization through integration of conversion and shielding materials. The resulting flexible arrays can be handled, integrated, further functionalized and deployed for a wide variety of applications where conventional sensors do not provide the desired functionality, form factors and/or reliability. The arrays can be stacked and include multiple types and thicknesses of conversion layers, enabling the detector to simultaneously detect multiple radiation types, and perform complex, simultaneous functions such as energy discrimination, spectroscopy, directionality detection, and particle trajectory tracking of incident radiation.
