“…It provided the best performance and least degradation of 12 advanced solar array experiments that flew on the mission in a high radiation orbit. 4 SCARLET, a line focused concentrator, evolved from this and was launched in 1998 on Deep Space 1 and performed flawlessly on a 38 month mission 5 . Both PASP+ and SCARLET are pictured in Fig.…”

In past years, very few satellites have flown in orbits that require long durations in the Van Allen radiation belts due to the loss of power, hence lifetime, caused by the radiation. Another recurring obstacle to reliable power in space is electrostatic discharge which is most prevalent in GEO. As power levels continue to increase, arcing failures will become more prevalent. An array that can withstand high voltage, high radiation operation while being lightweight and cost efficient is necessary for the future of the space industry. The Stretched Lens Array (SLA) developed by ENTECH, Inc. is a viable candidate. This paper will discuss recent advances, past and future testing protocols, flight history, and the ability of the SLA to reliably fly in harsh orbits.

“…Beginning in the mid-1990s, a number of space experiments with modules based on Fresnel lens concentrators (mini-dome point focus module for PASP Plus mission [1], flat-plate point focus module for "Molnija 3K" spacecraft [2], SCARLET linearfocus array [3] for DS1, SLA (Stretched Lens Array) for TacSat-4 satellite [4]) and reflecting CellSaver systems [5] have been successfully conducted. Currently, researchers are preparing space tests with an improved Stretched Lens Array SquareRigger (SLASR) system [6].…”

Abstract:In the work, the results of an investigation of GaInP/GaInAs/Ge MJ SCs intended for converting concentrated solar radiation, when operating at low temperatures (down to -190 o C) are presented. A kink of the cell I-V characteristic has been observed in the region close to V oc starting from -20ºC at operation under concentrated sunlight. The causes for its occurrence have been analyzed and the reasons for formation of a built-in potential barrier for majority charge carriers at the n-GaInP/n-Ge isotype hetero-interface are discussed. The effect of charge carrier transport in n-GaInP/n-p Ge heterostructures on MJ SC output characteristics at low temperatures has been studied including EL technique.

“…1 flew in 1994-95 on the NASA/USAF year-long PASP-Plus flight test in a very high-radiation elliptical orbit (363 km by 2,550 km at 70-degree inclination). Of the 12 advanced photovoltaic array types included on PASP-Plus, the minidome lens provided the highest performance and the least degradation 2 .…”

For the past three years, our team has been developing, refining, and maturing a unique solar array technology known as Stretched Lens Array SquareRigger (SLASR). SLASR offers an unprecedented portfolio of state-of-the-art performance metrics, including areal power density, specific power, stowed power density, high-voltage capability, radiation hardness, modularity, scalability, mass-producibility, and cost-effectiveness. SLASR is particularly well suited to high-power space missions, including solar electric propulsion (SEP) space tugs, major exploration missions to the Moon and Mars, and power-intensive military spacecraft. SLASR is also very well suited to high-radiation missions, since the cell shielding mass penalty is 85% less for the SLASR concentrator array than for one-sun planar arrays. The paper describes SLASR technology and presents significant results of developments to date in a number of key areas, from advances in the key components to fullscale array hardware fabrication and evaluation. A summary of SLASR's unprecedented performance metrics, both near-term and longer term, will be presented. Plans for future SLASR developments and near-term space applications will also be outlined.
