The SAA is part of the Rover which will be launched as part of the European Space Agency's ExoMars Mission under subcontract to the mission prime Thales Alenia Space. Airbus UK has the responsibility of the vehicle, Leonardo of the solar Array including the electrical part, while Sener is responsible for the mechanism part. The ExoMars Rover and Surface Platform, respectively named Rosalind Franklin and Kazachok, planned for launch in 2020 is a large international cooperation between the European Space Agency and Roscosmos with a contribution from NASA. All potential critical requirements have been identified and covered by a specific qualification testing. The biggest challenge in terms of development and qualification efforts is related to surviving Mars planet environment (i.e. dust and wind) and the system mechanical and electrical constraints.","PeriodicalId":6734,"journal":{"name":"2019 European Space Power Conference (ESPC)","volume":"10 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80473085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are used to protect and distribute power as described and required by the ECSS-E-ST-20-20C standard [1]. A crucial aspect of these devices is the current control loop aiming at limiting the current in case of overload or short circuit. On one hand the fastest possible response is required to LCLs when a load fault condition occurs; on the other hand a minimum stability criterion needs to be respected. This paper presents a comparison between three different topologies of control loop: the first one based on a resistive feedback with only a proportional action, the second featuring a topology based on an inductive feedback, with proportional and derivative action, and the third based on an Op Amp, with derivative and integral action. The comparison, mainly based on the ECSS standard, investigates both theoretical and experimental results. These latter derive from tests conducted on prototypes and/or boards intended to find application in space missions. The solution relying on resistive feedback offers a very simple and cost effective solution, while the architecture based on inductive feedback uses an inductor in series with the shunt resistor which results in a reduction of the Current Overshoot as practical experiments demonstrate. Finally, the Op Amp based topology offers a better control of the current limitation value over the other two solutions.","PeriodicalId":6734,"journal":{"name":"2019 European Space Power Conference (ESPC)","volume":"51 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88418920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose a new concept based on a static (without deployment) compact refractive micro-concentrator. The feasibility of the concept was demonstrated thanks to the realization of a concentrator module which was characterized electrically. To go further, cost and mass are key parameters. To reduce the mass the route is combining the reduction of the cell size to the reduction of the concentrator size/thickness. Subwavelength optics, a family of optics composed of structures with sizes that are smaller than the wavelength, are interesting candidates for flat and lightweight components which are applied to solar generator. We will also discuss possible manufacturing approaches for implementation of such concept.","PeriodicalId":6734,"journal":{"name":"2019 European Space Power Conference (ESPC)","volume":"4 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91327715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several situations derive from the series association of subcells within a multijunction solar cell, among others, that the cell limiting in current might be reverse biased under certain operational conditions. The subcell limiting can change due to varying spectral measurement conditions or because of different degradation rates of the subcells at end of life. The model described here is based on Ecosim and allows a complete simulation of the current-voltage characteristic of the solar cell, taking into account the reverse performance. This model offers a tool to assess the impact of different spectral conditions on the current-voltage characteristic of the solar cell that might occur in long duration tests under illumination. The modelling validation has been supported with measurements of triple junction solar cells and components performed in ESTEC laboratories. In summary, the core idea of the paper is to extend the modelling of the solar cell to reverse voltages, obtaining thus a tool that can reproduce the performance of the cell in all possible bias conditions.","PeriodicalId":6734,"journal":{"name":"2019 European Space Power Conference (ESPC)","volume":"42 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75131601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They suffer from high reflection in the infrared spectrum and if un-encapsulated, are prone to mechanical damage and performance losses. We present in this paper a flexible thin single layer protection coating which enhances the emissivity of CIGS from 0.3 to 0.7 but is transparent enough to have no detrimental effect on electrical performance as was measured under AM0 illumination. The coated CIGS samples passed the thermal vacuum outgassing test and the coating process can be easily scaled up for larger modules. Large coated CIGS modules showed no performance degradation and mechanical cracks after they underwent vibration test. By replacing cover glasses on solar modules, the coating can significantly reduce specific weight of solar modules and the associated payload costs.","PeriodicalId":6734,"journal":{"name":"2019 European Space Power Conference (ESPC)","volume":"181 Suppl 1 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81810513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
