Thin and Automated Blanket Lamination and Encapsulation Systems (TABLES)

The availability of very high power photovoltaic arrays can extend NASA's reach in achieving its missions. A variety of missions being considered, including travel to asteroids, Mars, the Lagrange points, lunar surface, or outer planets need very high power to enable space mission capabilities, including electric propulsion and manned spaceflight needs. Flexibility may also provide means for sufficient aperture to collect sunlight in low illumination outer planet environments. The incorporation of IMM solar cells into flexible blankets offers an opportunity to increase conversion efficiency while drastically increasing the effective specific power, rendering the proposed concept useful for a wide variety of NASA applications.

Solar array power availability drives the capabilities and costs of many commercial spacecraft. New "all-electric" spacecraft using electric propulsion to enhance mission life while reducing launch mass are driving prime power requirements to ever higher levels. Additional power provides more transponders and improved signal strength, and allows for longer life because of the affordability of oversizing and redundancy. The trend on commercial spacecraft being developed by Boeing, Lockheed Martin, Loral, and Orbital Sciences, among others, is for larger, higher power GEO spacecraft growing beyond 20kW. A significant market also exists worldwide for more low to medium-power arrays, and as the CIGS technology is demonstrated in PARASol, scaled down version of the design will be marketed for applications in the 5-20kW range typical of commercial GEO spacecraft, and even smaller arrays for Smallsats and deployable Cubesats. Long duration, High altitude airships could also use deployed, towed arrays to enhance their capabilities and time aloft. More »
