“…[50] The aforementioned features of PSCs make them promising candidates for space PVs for many reasons. In particular, low weight and flexibility are pivotal requirements for space applications, not only to reduce the launching costs of spacecraft but also to allow the fabrication of roll-out solar arrays, [4,51,52] which are currently produced by using rigid, thick, and heavy SCs (such as Si-and InGaP/GaAs/Ge-based devices). To promote the space applications of PSCs, a few groups have already investigated the effects of various extreme space environments on the perovskite films and PSC's performance.…”

Space solar cells, which directly convert solar energy into electricity, have been providing a consistent supply of energy for various spacecraft for decades. Currently, the third‐generation solar cells incorporating innovative materials and technologies, such as perovskite solar cells and organic solar cells, have demonstrated significant potential for space applications. However, their real performance in space environments is not yet clear. To assess crucial performance parameters, including short‐circuit current, open‐circuit voltage, and the current‐voltage (I‐V) curve, solar cells need to be calibrated under the standard space spectral irradiance before deployment in space. This is known as AM0 calibration, and failure to adhere to this calibration process may results in the need for larger redundant which leading to increased weight. Over the years, global efforts by space solar cell manufacturers, space agencies, and researchers were made to improve the quality of space solar cell calibration. These efforts include developing calibration devices, conducting calibration experiments, accessing calibration accuracy and error sources, and establishing calibration standards. This review paper focused on the calibration and measurement techniques and different calibration methods for space solar cells. The topics covered include space environment and standard testing condition for solar cells, the measurements of key parameters for traditional solar cells, advancements in perovskite solar cells and organic solar cells for space applications, and a comprehensive review of diverse calibration methods. The discussion spans from near‐ground calibration to near‐space calibration and space calibration, encompassing approaches, key technologies, developmental milestones, and the respective merits of each calibration methods, especially focus on high altitude balloon calibration. Finally, the paper addresses the challenges and future trends of space solar cell calibration based on the aforementioned discussions.This article is protected by copyright. All rights reserved.

Hybrid Extendable Linear Actuators: Design and Applications

2019

There are many types of different actuators in the field of robotics. For applications where a linear displacement is required, a linear extendable actuator would be the method of choice. The hybrid class of extendable actuators possesses unique features making it suitable for many applications where the soft and rigid types fall short. However, there has not been a clear designation and classification of extendable linear hybrid actuators in the literature. This paper addresses this matter and provides the first overview of the hybrid class of extendable actuators. The paper performs a categorization and characterization of this class of extendable linear actuators based on their method of operation as well as the inherent unique features separating them from the rest. The paper contains five sections, and three sub-sections pertaining to the different categories of Hybrid actuators, and their applications. New research in this field continues to add features to this class of actuators through improvements and added capabilities.

“…Due to this technology, a reduction of 33% in mass and of a factor of 4 in volume is attained with respect to an equivalent rigid panel. 22 Another notable example is constituted by the NASA's Deployable Composite Booms (DCB) project, which aims to develop a 54-foot long thin-shell composite boom to be used for supporting deployable systems, such as solar sails (up to 2000 m 2 ) 23 and arrays, or for instrumentation-hosting purpose. However, in current boom designs, the gain of cross-section inertia after deployment is directly dependent on the width of the boom, with higher cross-section inertia requiring a boom that is larger in the transversal dimension.…”

Flat-fabrication technology may enable the next generation of gigantic deployable architectures devoted to the detection of faint cosmological signals. We assess the applicability of a multifunctional roll-out structure based on shape memory polymer technology for the realization of a large space observatory to measure the cosmological Dark Ages radio signal. Roll-out solutions offer advantageous properties for probe class missions, such as the capability to morph the shape to achieve sufficient structural performance while ensuring high packaging efficiency. We characterize the feasibility of a roll-out observatory in the context of a 5 years-long heliocentric mission scenario. Our preliminary study demonstrates how a four-250 m-long arms architecture with 150 evenly spaced short dipole antennas potentially meets the basic mission requirements dictated by the Dark Ages science case. We conduct a quasi-static structural analysis considering axial and bending loads acting on the arms to assess the structural properties of the proposed architecture, identifying geometric ranges which enable the structure to withstand expected loads while satisfying mass and size constraints. Printable electronics are considered in the design due to the ease of integration with the polymer substrate. In this regard, we explore two distinct electronics configuration options-centralized and decentralizeddiscussing their benefits in terms of power demand and data management. If successful, such a design may set the stage for future technological development aiming to realize tomographic measurements of the cosmological Dark Ages.
