Impact of a Short‐Pulse High‐Intense Proton Irradiation on High‐Performance Perovskite Solar Cells

Abstract

This work investigates the radiation resistance of high‐performance multi‐component perovskite solar cells (PSCs) for the first time under extreme short‐pulse proton irradiation conditions. The devices are subjected to high‐intensity 170 keV pulsed (150 ns) proton irradiation, with a fluence of up to 1013 p cm−2, corresponding to ≈30 years of operation at low Earth orbit. A complex material characterization of the perovskite active layer and device physics analysis of the PSCs before and after short‐pulse proton irradiation is conducted. The obtained results indicate that the photovoltaic performance of the solar cells experiences a slight deterioration up to 20 % and 50 % following the low 2 × 1012 p cm−2 and high 1 × 1013 p cm−2 proton fluences, respectively, due to increased non‐radiative recombination losses. The findings reveal that multi‐component PSCs are immune even to extreme high‐intense short‐pulse proton irradiation, which exceeds harsh space conditions, including intense coronal ejection events usually associated with solar flares.

MXenes as a hole transport interfacial layer for efficient and air-stable quasi-2D perovskite solar cells

“…Furthermore, to confirm the passivation effect on the recombination centers (pinhole defect), steady-state measurements of the V oc have been performed under different intensities of light, which is an efficient qualitative method to determine the dominant mechanism of recombination losses in photovoltaic devices. 52 The slope of the V oc versus light intensity is a pointer to the dominant recombination mechanisms. The 2D-PVSK-based device revealed a slope of 1.59 kT q −1 (Fig.…”

Annual research review of perovskite solar cells in 2023

“…The radiation stability of Cs 0.04 Rb 0.04 (FA 0.65 MA 0.35 ) 0.92 Pb(I 0.85 Br 0.14 Cl 0.01 ) 3 PSCs was analyzed under extreme conditions of short-pulse (150 ns) 170 keV proton irradiation, which is equivalent to ∼30 years at the low earth orbit. Results revealed its outstanding radiation stability along with slight degradation in its photovoltaic performance, which was mainly induced by proton irradiation and a considerable increase in the recombination losses resulting from bulk and surface traps [309].…”
