This is a $3,246,314.00 cost-plus-fixed-fee contract awarded by NASA's Glenn Research Center to The Boeing Company for the development of advanced solar cell modules for deep space missions. The contract aims to advance the technology readiness level (TRL) of these solar cell modules from TRL 4 to TRL 5 through a base project and two option periods. Key aspects of the work include system engineering, design and analysis, fabrication, and testing of a breadboard multi-junction solar cell module (MCM). Boeing is working with subcontractors Deployable Space Systems (DSS) and Orbital ATK to ensure the MCM is compatible with their respective deployment systems. This contract is not set aside for small businesses.

Statement of work NASA is considering the development of solar cells solar array design concepts better suited for missions that require exposure to more intense radiation environments and missions ever farther from the sun. In support of that goal, NASA is examining promising technologies with the potential to increase solar cell conversion efficiencies under low intensity low temperature lilt and high radiation environments. The contractor shall perform the following work scope to complete the advanced solar cell module effort and advance the TRL to 4 at the end of the base project, to TRL 5 at the end of the first option, and even further by the end of the second option. 1.0 base project 1.1. Program management 1.1.1. Manage the extreme environments solar array program by ensuring that all tasks are supported and executed in a timely manner, supporting status meetings as necessary with the customer, preparing for customer reviews, and documenting the program progress. Tasks include program, business, and administrative planning, organizing, directing, coordinating, controlling, and approval actions. 1.2. System engineering 1.2. Support in person a program kickoff technical exchange meeting TIM at NASA glenn research center. 1.2.2. Provide periodic every 3 months status reports on the progress of the program 1.2.3. Support a virtual technical exchange meeting TIM with the customer on the overall program status approximately 4 months after program kickoff. 1.2.4. Work with all the stakeholders to define the top level system requirements for a deep space solar mission. These requirements then need to be flowed down to the MCM design team so they can design the MCM. 1.2.5. After the breadboard MCM testing is complete, evaluate the TRL level and assess the ability to get to TRL 5 in option i. 1.2.6. After the breadboard MCM testing is complete, assess the technology performance against key figures of merit from the program. 1.2.7. Compile and deliver an overall final oral presentation on the base project of the program to the customer at boeings facility in EL segundo, CA. 1.2.8. Prepare and deliver a final summary report on the base project of the program to the customer. 1.3. Design and analysis 1.3.1. Design production packaging for production MCM. This includes designing the deployable tether and spring mechanism to increase the stowed packing efficiency. 1.3.2. Develop production circuit layout for production MCM. 1.3.3. Perform a thermal analysis of the production MCM. 1.3.4. Provide a detailed technical description of the solar cell materials, FAB techniques, and components of the production MCM to the customer. 1.3.5. Preliminary radiation modeling and analysis. 1.4. Fabrication 1.4.1. Spectrolab will fabricate one 1 breadboard MCM using parts left over from the homesteader program and perform acceptance testing on IT. 1.5. Test 1.5.1. Perform a mems screening test on the breadboard MCM. 1.5.2. Perform a characterization test of the breadboard MCM before and after each test. 1.5.3. Perform x 25 bare cell electrical test on the CPV optimized bare solar cell. 1.5.4. Perform a thermal cycle test on the breadboard MCM. 1.5.5. Perform a thermal vacuum test on the breadboard MCM. 1.5.6. Perform an interconnect wire bond pull test on solar cell and mirror assembly. 1.6. DSS subcontract 1.6.1. Work with boeing to develop interface requirements on the MCM to ensure IT will be compatible with the rosa deployment system. 1.6.2. Develop a preliminary design of a base solar wing, including a mass summary and stowed volume calculation. 1.7. Orbital ATK subcontract 1.7.1. Work with boeing to develop interface requirements on the MCM to ensure IT will be compatible with the mega flex deployment system. 1.7.2. Develop a preliminary design of a base solar wing, including a mass summary and stowed volume calculation. 1.8. JPL subcontract 1.8.1. Work with boeing to devel
