“…[16][17][18] Beyond conventional terrestrial implementation, [19][20][21] perovskite solar cells have recently found their potential applications for near-space and polar-region use in other extreme conditions. [22][23][24] Spacecraft often use high efficiency single-crystal Si or III-V semiconductor solar cells as the source of power generation. Photovoltaic devices for space applications have strict requirements, including high PCE with high specific power and specific volume, tolerance of space radiation damage, and stable performance through thermal cycling.…”

The photovoltaic performance of hybrid halide perovskite solar cells at extreme low temperatures is investigated in depth. Enhanced open-circuit voltage and efficiency are found at temperatures from 290 to 180 K. The mechanism is related to phase-transition-induced self-elimination of intrinsic defects for perovskites at low temperatures. The highest efficiency over 25% at 220 K is ultimately achieved to demonstrate the feasibility of perovskite solar cells in an aerospace environment chamber.

“…Indeed, several reports show the decomposition of MAPbI3 to PbI2 after even soft X-ray exposure 39 . On the other hand radiation tolerance 26 or even radiation enhanced behaviour is also frequently reported for HHPs. 27 This remarkable radiation resistance is referred to the "self-healing" i.e.…”

Detection and direct power conversion of high energy and high intensity ionizing radiation could be a key element in next generation nuclear reactor safety systems and space-born devices. For example, the Fukushima catastrophe in 2011 could have been largely prevented if 1% of the reactor's remnant radiation (γ-rays of the nuclear fission)were directly converted within the reactor to electricity to power the water cooling circuit. It is reported here that the hybrid halide perovskite methylammonium lead triiodide could perfectly play the role of a converter. Single crystals were irradiated by a typical shut-down γ-spectrum of a nuclear reactor with 7.61×10 14 Bq activity exhibit a highefficiency of γ-ray to free charge carrier conversion with radiation hardening. The power density of 0.3 mW/kg of methylammonium lead triiodide at 50 Sv/h means a four times higher efficiency than that for silicon-based cells. The material was stable to the limits of the experiment without changing its performance up to 100 Sv/h dose rate and 57 Sv H*(10) ambient total γ-dose. Moreover, the γ-shielding performance of methylammonium lead triiodide was found to be superior to both ordinary and barite concrete.

“…Another attractive characteristic of perovskites is their tolerance to ionizing radiation. Tests done at Caltech [51] and elsewhere [52], [53] have shown that while perovskites suffer some displacement damage in high radiation fields, the damage can be annealed out to return the device to its undamaged operating state. This eliminates the need for cover glass, greatly reducing the mass of the cells.…”

Most existing space solar power concepts place one or more power stations in geosynchronous Earth orbit (GEO). However, due to the limited availability of GEO orbital slots, it may not be feasible to locate a power station in GEO. To overcome this limitation, this paper presents a system analysis for a space solar power system that incorporates a constellation of power stations in a 20,184 km altitude equatorial medium Earth orbit (MEO). The orbiting power stations are based on the Caltech Space Solar Power Project architecture. The constellation consists of multiple power stations in a shared equatorial MEO each transmitting to a non-equatorial receiving station. The analysis assumes a one-to-one correspondence between the number of power stations and the number of ground stations. Like a GEO-based system, this constellation architecture enables a MEO-based system to provide near continuous power (outside of eclipse) to each ground station. It is shown that a MEO constellation with three or more power stations provides comparable transmission efficiency to a GEO-based system. The Levelized Cost of Electricity (LCOE) is then computed for MEO systems with three, four, and five power stations and compared to the LCOE for the GEO-based system. Ground station area is identified as a significant contributor to the LCOE for the MEO-based systems. The system analysis shows that a MEO constellation with as few as four power stations has an LCOE comparable to GEO, and hence, it is concluded that MEO is a viable alternative to GEO for space solar power.
