    Shenzhen, May 19, 2026<\/strong> \u2014 Shenzhen Hiking PV Technology Co., Ltd. (HIKING PV) announced that its self-developed perovskite-silicon tandem solar cell has completed a 1\u00d710\u00b9\u2075 p\/cm\u00b2 at 400 keV high-dose proton irradiation test. The test results show that, under this sample set and test condition, the tandem cell\u2019s proton irradiation resistance was close to that of a conventional aerospace-grade P-type crystalline silicon solar cell.<\/p>\n\n\n\n

    The test is part of HIKING PV\u2019s staged reliability validation work for space PV applications. The results provide additional data reference for evaluating perovskite-silicon tandem cells in low-Earth-orbit satellites, near-space vehicles, and other commercial space scenarios.<\/p>\n\n\n\n

    About 12% Relative Efficiency Degradation, Within the Grade A Radiation-Resistance Range<\/h2>\n\n\n\n

    Proton irradiation is an important reliability test for space solar cells. In low-Earth-orbit environments, high-energy charged particles such as protons and electrons can cause long-term performance degradation in solar cells. Radiation resistance is therefore a key indicator that needs to be validated before new photovoltaic devices are evaluated for space applications.<\/p>\n\n\n

    The test data show that after 1\u00d710\u00b9\u2075 p\/cm\u00b2 at 400 keV proton irradiation, HIKING PV\u2019s perovskite-silicon tandem cell had about 12% relative efficiency degradation, within the Grade A radiation-resistance evaluation requirement. As a reference, a conventional aerospace-grade P-type crystalline silicon solar cell showed about 13% relative efficiency degradation under the same test conditions.<\/p>\n\n\n\n

    Based on this round of testing, HIKING PV\u2019s perovskite-silicon tandem cell demonstrated good performance retention under high-dose proton irradiation. Its radiation-resistance level was broadly comparable to that of the reference aerospace-grade P-type crystalline silicon cell.<\/p>\n\n\n

    Building Staged Data for Space Application Reliability Evaluation<\/h2>\n\n\n\n

    Perovskite-silicon tandem solar cells combine high conversion-efficiency potential with industrial scalability, and are regarded as an important direction for next-generation high-efficiency PV technology. For space PV applications, long-term stability under irradiation, temperature changes, and other complex environmental conditions is as important as conversion efficiency.<\/p>\n\n\n\n

    Before this proton irradiation test, HIKING PV\u2019s perovskite-silicon tandem cell had completed a \u00b1100\u00b0C extreme thermal shock test, initially validating its structural stability and performance retention under sharp temperature changes. The completion of this high-dose proton irradiation test further enriches the product\u2019s test data for space-environment adaptability.<\/p>\n\n\n\n

    HIKING PV said the test result represents staged progress in the company\u2019s evaluation of tandem cells for space applications. The company will continue to advance multiple ground-based simulations of space environments, optimize tandem solar cell performance, and improve operating reliability and scenario adaptability under extreme and complex working conditions.<\/p>\n","protected":false},"excerpt":{"rendered":"
