Description

Flexible flexible solar cell panel that curls

Technical Field

The utility model relates to a flexible solar cell panel technical field for spacecraft or satellite are used, concretely relates to solar cell panel that can curl.

Background

Solar arrays relate to structures attached to certain spacecraft vehicles or satellites to power the spacecraft, solar arrays take up little space to store for easy shipping and launching, and photovoltaic solar panels can be deployed in space to convert solar energy into kinetic energy needed to operate the spacecraft.

Power systems for space applications face a number of design constraints, including criteria to minimize weight, minimize storage volume, maximize life-to-end-of-life performance, and minimize cost.

To allow for further reduction in the weight and storage volume of the deployable solar cell array, the solar cells may be mounted to a lightweight flexible substrate or blanket rather than a large heavy rigid honeycomb panel. Various flexible solar cell cover substrates have been used, such as those made of fiberglass mesh or thin polymer sheets, to which numerous crystalline solar cells are bonded.

Flexible Photovoltaic (PV) blanket solar cell arrays are typically limited to crystalline solar cells packaged on long continuous rolls or pleated and folded stacks that are connected and unfolded by a separate deployment arm actuator, hub structure or other deployable structure requiring an external motor power supply.

Solar cells are by far the most expensive component of a solar cell array. Since both system cost and quality increase directly with the number of solar cells used, there is considerable economic incentive to reduce the number of solar cells carried by the spacecraft.

By using relatively inexpensive Fresnel lens optics to collect and focus sunlight onto smaller solar cells, the cost and weight of the cells for an equivalently powered solar cell array is significantly reduced. By using very efficient cells, the required array area is minimized, reducing the overall system weight.

The lens assemblies and lens banks are thin lightweight rollable curvilinear elements, flat or arched, made of flexible DC93500 silicone elastomer material, with a protective front side coating, mounted directly above the solar cell bank and positioned precisely so that it captures incident solar radiation (light) and refracts it onto the solar cell row directly below to increase the illumination of the cells.
