The general chemical formula of metal halide perovskite is ABX 3 , where A is a monovalent cation (such as FA + [ formamidinium], MA + [methylammonium], or Cs + ), B is a divalent metal cation (such as Pb 2+ , Sn 2+ , or Ge 2+ ), and X is a monovalent halogen anion (such as I − , Br − , or Cl − ). [9] Photovoltaic devices based on perovskite absorbers have achieved a certified power conversion efficiency (PCE) of 25.5% [10] in single-junction devices and obtained a PCE above 26.7% [11] in tandem devices, in which the best PCE is comparable to those of some commercially available products on the photovoltaic market, such as crystalline silicon (HIT, champion PCE of 26.7%), cadmium telluride (CdTe, champion PCE of 22.1%), gallium arsenide (GaAs, champion PCE of 27.8%), and copper indium gallium selenide (CIGS, champion PCE of 23.4%) solar cells. In particular, only sub-micron-thick absorber is needed in perovskite solar cells because of perovskite's high optical absorption coefficient of about 10 4 cm −1 , [12] therefore high specific power is expected. Combined with the low-temperature solution processability and radiation resistance, [13] these features render PSCs as a Metal halide perovskites have aroused burgeoning interest in the field of photovoltaics owing to their versatile optoelectronic properties. The outstanding power conversion efficiency, high specific power (i.e., power to weight ratio), compatibility with flexible substrates, and excellent radiation resistance of perovskite solar cells (PSCs) enable them to be a promising candidate for next-generation space photovoltaic technology. Nevertheless, compared with other practical space photovoltaics, such as silicon and III-V multi-junction compound solar cells, the research on PSCs for space applications is just in the infancy stage. Therefore, there are considerable interests in further strengthening relevant research from the perspective of both mechanism and technology. Consequently, the approaches used for and the consequences of PSCs for space applications are reviewed. This review provides an overview of recent progress in PSCs for space applications in terms of performance evolution and mechanism exploration of perovskite films and devices under space extreme environments.

Non‐Uniform Chemical Corrosion of Metal Electrode of p–i–n Type of Perovskite Solar Cells Caused by the Diffusion of CH₃NH₃I

et al. 2020

Although perovskite solar cells have shown high power conversion efficiency, performance stability is still insufficient. Herein, the decay kinetics of the p–i–n type of perovskite cells under light illumination is monitored. It is found that the degradation of the performance is mainly caused by the decrease in short‐circuit current (JSC), which is directly related to the loss of active area. Secondary ion mass spectrometry (SIMS) analysis confirms that both CH3NH3+ and I− migrate toward the metal electrode during aging through the thin PC61BM layer. Atomic force microscope (AFM) and scanning electron microscope (SEM) analyses reveal that some part of the PC61BM layer is too thin to cover the rough surface of the perovskite film fully. Therefore, chemical corrosion of the metal electrode by CH3NH3I leads to the loss of active area and the consequent short circuit current is proposed to be the performance decay mechanism of perovskite solar cells, which is further supported by the stability improvement of the cells by inserting a thin bathocuproine (BCP) buffer layer between the metal electrode and PC61BM, where the CH3NH3I migration is blocked by the BCP layer.

“…The power conversion efficiency (PCE) dropped with 36% after the balloon flight. [ 11 ] Several accelerated tests exposing the solar cells to high doses of high energy radiation using electrons, [ 12 ] protons, [ 13,14 ] neutrons, [ 15 ] and gamma‐rays [ 16 ] have also been performed in PSCs. In all but one case, the initial PCE of the used cells was in between 5% and 14%, which may not be representative as only high‐efficiency PSCs will eventually be used in space missions.…”

Perovskite Solar Cells: Stable under Space Conditions

et al. 2020

Metal halide perovskite solar cells (PSCs) are of interest for high altitude and space applications due to their lightweight and versatile form factor. However, their resilience toward the particle spectrum encountered in space is still of concern. For space cells, the effect of these particles is condensed into an equivalent 1 MeV electron fluence. The effect of high doses of 1 MeV e‐beam radiation up to an accumulated fluence to 1016 e− cm−2 on methylammonium lead iodide perovskite thin films and solar cells is probed. By using substrate and encapsulation materials that are stable under the high energy e‐beam radiation, its net effect on the perovskite film and solar cells can be studied. The quartz substrate‐based PSCs are stable under the high doses of 1 MeV e‐beam irradiation. Time‐resolved microwave conductivity analysis on pristine and irradiated films indicates that there is a small reduction in the charge carrier diffusion length upon irradiation. Nevertheless, this diffusion length remains larger than the perovskite film thickness used in the solar cells, even for the highest accumulated fluence of 1016 e− cm−2. This demonstrates that PSCs are promising candidates for space applications.
