About this file
This document is a Statement of Work (SOW) for a LED Solar Simulator requirement by the National Aeronautics and Space Administration (NASA) Marshall Space Flight Center (MSFC). The key details are:
The scope is to acquire a fully integrated photovoltaic performance characterization system to test state-of-the-art solar arrays for space applications, including inverted metamorphic multijunction (IMM) solar cell technology with 3, 4, or 5 junctions. The system must meet specific requirements such as programmable LED-based light sources, compliance with Air Mass Zero (AM0) spectrum, pulsed output, modular design, minimum 3ft x 3ft output coverage area, and capabilities to accurately measure the performance of various space-grade cell technologies. The place of performance is at the MSFC Building 4475, Room 130 in Huntsville, AL, and the period of performance is 16 weeks ARO.
The related pre-solicitation notice indicates that NASA ITPO is seeking capability statements from interested parties, including small businesses and underserved communities, for the purposes of determining the appropriate level of competition and/or small business subcontracting goals. The Government reserves the right to consider a small business set-aside. Responses are due by Wednesday, June 26, 2024, at 12 PM EST.

STATEMENT OF WORK
LED Solar Simulator
1. Objective/Requirements
NASA Marshall Space Flight Center requires the purchase of a LED Solar Simulator to enhance solar array testing capability which will directly support Human Landing System (HLS) and Habitation programs such as Gateway and Surface Habitats. This will also support any MSFC-involved spaceflight mission utilizing solar arrays for power generation.
2. Characteristics, Scope, and Specs
The scope of this procurement is to acquire a fully integrated photovoltaic performance characterization system to test state-of-the-art solar arrays for space applications, including inverted metamorphic multijunction (IMM) solar cell technology with 3, 4, or 5 junctions. To accommodate the advancements in solar cell technology this test system requires highly specialized equipment for control and tunability. To test the solar array performance in a space environment with no atmospheric attenuation of solar radiation this test system will require enough power to achieve AM0 (air mass zero) spectrum output. To achieve the control, tunability, and spectrum output for testing at AM0 this needs to be a programmable LED-based test system capable of properly biasing and doing independent current control of the following solar cell technologies:
ꞏ SolAero: ZTJ, Z4J, IMM-alpha, IMM-beta, Z4J+ ꞏ Spectrolab: XTJ, XTE-SF, … all Spectrolab UMM 3J cells ꞏ Azur: 3G30, 4G32 ꞏ
Our testing applications require a pulsed beam output area of at least 3ft x 3ft, and we need the system to be modular with the ability to be upgraded as solar cell technology continues to advance in the future.
Solar Simulator shall meet or exceed the following specifications:
1. Programmable LED-based light sources.
2. Output compliance with Air Mass Zero (AM0) spectrum for space-grade photovoltaic cells.
3. Pulsed output.
4. Modular system able to add or remove LED sources.
5. Minimum output coverage area of 3-feet x 3-feet.
6. Source Measure Unit (SMU) for current-voltage measurement linked to LED programmable driver.
7. High Voltage Multiplexer.
8. Desktop computer for operation and control.
9. Software for fully automated calibration and testing, and fully programmable spectral and irradiance control.
10. Motorized frame for fully automated, vertically oriented calibration and testing.
11. Rated for characterizing 3, 4, or 5 junction photovoltaic cells, including inverted metamorphic multijunction (IMM) cells.
12. Capable of accurately measuring the performance of the following space-grade cell technologies:
ꞏ SolAero: ZTJ, Z4J, IMM-alpha, IMM-beta, Z4J+ ꞏ Spectrolab: XTJ, XTE-SF, UMM 3J cells ꞏ Azur: 3G30, 4G32
13. On-site training.
3. Place of Performance
NASA – Marshall Space Flight Center (MSFC) Building 4475, Room 130 Huntsville, AL 35808
4. Period of Performance
16 Weeks ARO
