High-power microwaves response characteristics of silicon and GaAs solar cells

Abstract

The high-power microwave (HPM) effect heats solar cells, which is an important component of a satellite. This creates a serious reliability problem and affects the normal operation of a satellite. In this paper, the different HPM response characteristics of two kinds of solar cells are comparatively researched by simulation. The results show that there are similarities and differences in hot spot distribution and damage mechanisms between both kinds of solar cell, which are related to the amplitude of HPM. In addition, the duty cycle of repetition frequency contributes more to the temperature accumulation of the solar cells than the carrier frequency. These results will help future research of damage assessment technology, reliability enhancement and the selection of materials for solar cells.

Ordered Anodic Aluminum Oxide-Based Nanostructures for Surface-Enhanced Raman Scattering: A Review

“…With a deeper understanding of the CM mechanism, many researchers have devoted themselves to combining plasmonic metals with other materials such as metals, semiconductors, and graphene, to establish new electron transport pathways through interfacial contacts, which benefits enhancing the SERS performance of each component. ,− Among these promising materials, semiconductors are of great interest for their high chemical stability, superior biocompatibility, and low preparation cost. By removing the oxide layer of AAO templates, Fan et al obtained periodic alumina nanobowl arrays and prepared an ordered MoO 2 /WO 3– x layer-by-layer heterostructure within the nanobowls of alumina templates .…”

Research Progress on Vanadium Sulfide Anode Materials for Sodium and Potassium‐Ion Batteries

“…Over the past few decades, the use of lithium-ion batteries (LIBs) in portable gadgets, electric vehicles, and huge energy systems has increased tremendously, driving up the demand for lithium resources. [1][2][3][4] Lithium only occurs in nature as compounds since it is a typical alkali metal element with high activity and low content when compared to its identical group sodium and potassium. [5,6] As a result, the price of lithium has been steadily increasing due to the difficulties of mining lithium deposits and the high demand.…”
