摘要

过氧化物太阳能电池（PSCs）在太空应用中大有可为。在这项研究中，基于 P3HT 的 PSCs 在室温下接受了 100 MeV 质子的不同通量辐照。在 1 × 1011p/cm2 的低通量辐照下，PSC 的效率显著提高了 30-35%。同时，辐照后还发现包晶体薄膜的光照产率和电荷载流子寿命得到了改善，这归因于辐照诱导了包晶体晶格缺陷的愈合。当辐照到 1 × 1012p/cm2 的较高通量时，由于色心缺陷的形成，玻璃基板的透射率明显降低，从而导致电池性能下降。考虑到基于 P3HT 的 PSC 对外太空的热稳定性优于广泛使用的基于螺-OMeTAD 的 PSC，报告的结果可能对 PSC 的太空应用具有重要意义。

Effects of 100 MeV proton irradiation on the performance of P3HT-based perovskite solar cells

Perovskite solar cells (PSCs) are promising for space applications. In this work, P3HT-based PSCs were irradiated at room temperature with 100 MeV protons to various fluences. The efficiencies of the PSCs were significantly increased by 30–35 % after irradiation with low fluences up to 1 × 10¹¹p/cm². Meanwhile, the illumination yields and charge carrier lifetime of the perovskite films were found to be improved after irradiation, which is attributed to the irradiation-induced healing of lattice defects in perovskites. When irradiated to a higher fluence of 1 × 10¹²p/cm², the transmittance of the glass substrates was distinctly reduced due to the formation of color-center defects, which resulted in the performance degradation of the cells. Considering that P3HT-based PSCs have better thermal stability in outer space than the widely used spiro-OMeTAD-based PSCs, the reported results may have important implications for space applications of PSCs.

期刊介绍： Section B of Nuclear Instruments and Methods in Physics Research covers all aspects of the interaction of energetic beams with atoms, molecules and aggregate forms of matter. This includes ion beam analysis and ion beam modification of materials as well as basic data of importance for these studies. Topics of general interest include: atomic collisions in solids, particle channelling, all aspects of collision cascades, the modification of materials by energetic beams, ion implantation, irradiation - induced changes in materials, the physics and chemistry of beam interactions and the analysis of materials by all forms of energetic radiation. Modification by ion, laser and electron beams for the study of electronic materials, metals, ceramics, insulators, polymers and other important and new materials systems are included. Related studies, such as the application of ion beam analysis to biological, archaeological and geological samples as well as applications to solve problems in planetary science are also welcome. Energetic beams of interest include atomic and molecular ions, neutrons, positrons and muons, plasmas directed at surfaces, electron and photon beams, including laser treated surfaces and studies of solids by photon radiation from rotating anodes, synchrotrons, etc. In addition, the interaction between various forms of radiation and radiation-induced deposition processes are relevant.
