“…[10] The radiation hardness of perovskite solar cells has been little investigated and is the subject of a few publications only. [11][12][13][14][15][16][17] In 2018, Miyasaka et al studied the radiation tolerance of perovskite solar cells composed of a mesoporous TiO 2 electron transport layer (ETL) and P3HT holes transport layer (HTL) to 1 MeV electrons and 50 keV protons and found that cells can survive to accumulated dose of 10 16 electrons cm À2 and 10 15 protons cm À2 , respectively. [14] For this study, P3HT was chosen as an HTL for its better thermal resistance compared with Spiro-OMeTAD, which is known to degrade at 80-100 C. P3HT showed robust radiation stability, but the power conversion efficiency (PCE) was rather low (4-5%) compared with state-of-the-art perovskite solar cells with Spiro-OMeTAD HTL (>20%).…”

“…The radiation hardness of p-i-n MAPbI 3 (inverted-type) solar cells to proton irradiation was also investigated by two other groups. [11,13,17] Huang et al showed that 50 keV protons with fluence 10 12 cm À2 cause a significant degradation of the performance of inverted perovskite cells, but these cells can be restored with a vacuum annealing process. Lang et al showed that the cells exposed to 20 and 68 MeV proton irradiation from the substrate side could withstand proton dose up to 10 12 protons cm À2 without significant damages.…”

Perovskite solar cells (PSCs) have gained increasing interest for space applications. However, before they can be deployed into space, their resistance to ionizing radiations, such as high-energy protons, must be demonstrated. Herein, the effect of 150 keV protons on the performance of PSCs based on aluminumdoped zinc oxide (AZO) transparent conducting oxide (TCO) is investigated. A record power conversion efficiency of 15% and 13.6% is obtained for cells based on AZO under AM1.5G and AM0 illumination, respectively. It is demonstrated that PSCs can withstand proton irradiation up to 10 13 protons cm À2 without significant loss in efficiency. From 10 14 protons cm À2 , a decrease in short-circuit current of PSCs is observed, which is consistent with interfacial degradation due to deterioration of the Spiro-OMeTAD holes transport layer during proton irradiation. The structural and optical properties of perovskite remain intact up to high fluence levels. Although shallow trap states are induced by proton irradiation in perovskite bulk at low fluence levels, charges are released efficiently and are not detrimental to the cell's performance. This work highlights the potential of PSCs based on AZO TCO to be used for space applications and gives a deeper understanding of interfacial degradation due to proton irradiation.

“…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.

“…Despite this, a few notable publications are investigating a wide range of energies, device architectures, perovskite compositions, and materials. [ 16–29 ] In 2015, and once again in 2018, Miyasaka et al showed that PSCs provide a much more robust radiation stable solar cell than their inorganic counterparts. In these publications, it was reported that PSCs utilizing a compact and mesoporous TiO 2 electron transport layer (ETL) and P3HT hole transport layer (HTL) are stable under an accumulated dose of 1 × 10 14 protons cm −2 for 50 keV protons and 1 × 10 16 electrons cm −2 for 1 MeV electrons.…”

Proton Radiation Hardness of Perovskite Solar Cells Utilizing a Mesoporous Carbon Electrode

When designing spacefaring vehicles and orbital instrumentation, the onboard systems such as microelectronics and solar cells require shielding to protect them from degradation brought on by collisions with high‐energy particles. Perovskite solar cells (PSCs) have been shown to be much more radiation stable than Si and GaAs devices, while also providing the ability to be fabricated on flexible substrates. However, even PSCs have their limits, with higher fluences being a cause of degradation. Herein, a novel solution utilizing a screen‐printed, mesoporous carbon electrode to act bi‐functionally as an encapsulate and the electrode is presented. It is demonstrated that the carbon electrode PSCs can withstand proton irradiation up to 1 × 1015 protons cm−2 at 150 KeV with negligible losses (<0.07%) in power conversion efficiency. The 12 μm thick electrode acts as efficient shielding for the perovskite embedded in the mesoporous TiO2. Through Raman and photoluminescence spectroscopy, results suggest that the structural properties of the perovskite and carbon remain intact. Simulations of the device structure show that superior radiation protection comes in conjunction with good device performance. This work highlights the potential of using a carbon electrode for future space electronics which is not limited to only solar cells.
