Abstract

UMM4J solar cells are evaluated under different LILT conditions. The efficiency findings near Earth’s orbit (1 sun, 300 K), Jupiter (0.032 sun, 123 K), and Saturn (0.01 sun, 100 K) are 26.54%, 29.68%, and 28.27%. According to single diode model, Jsc is linear with light intensity (I), while Voc is linear with the natural logarithm of light intensity (ln(I)). Voc shows a linear relationship with temperature within the range of 150K to 300K, with a temperature coefficient of ∽ ‐7. 7 mV/K. However, Voc displays a sublinear relationship with temperature below 150K.This article is protected by copyright. All rights reserved.

低强度和低温 (LILT) 对直立变质四结 (UMM4J) 太阳能电池的影响

在不同的 LILT 条件下对 UMM4J 太阳能电池进行了评估。地球轨道附近（1 个太阳，300 K）、木星（0.032 个太阳，123 K）和土星（0.01 个太阳，100 K）的效率分别为 26.54%、29.68% 和 28.27%。根据单二极管模型，Jsc 与光强 (I) 呈线性关系，而 Voc 与光强的自然对数 (ln(I)) 呈线性关系。在 150K 至 300K 范围内，Voc 与温度呈线性关系，温度系数为 ∽ -7.7 mV/K。然而，在低于 150K 的温度范围内，Voc 与温度呈亚线性关系。本文受版权保护。
