“…As far as power generation is concerned, solar cell efficiency has been increasing since the first delivery in 1954 [18]. Silicon (Si) cells were the main available technology from the 1960s to the 1980s, with efficiency increased from 10% in 1960 to 12% in 1970, reaching 15% in 1990.…”

“…Traditional solar cells are made of silicon, with low photovoltaic conversion efficiency of about 10% [20]. During the last 20 years, various new solar cells with new materials or structures have arisen such as GaAs/GaAs, GaAs/Ge, InP/InP, InP/Si, CdS/CdTe, CuInSedc, spotlight solar cell, amorphous silicon film cell, etc., which have high photovoltaic conversion efficiency (i.e., GaAs cells up to 30% [21]) and other excellent performances [22,23].…”

This article presents a new manufacturing process of bonding anti-irradiation cover glasses to silicon solar cells with silicone adhesive. Due to the disadvantages of traditional manual operation, a new manufacturing process was designed considering the characteristics of solar cells, cover glasses, and silicone adhesive, and was complemented by an automatic system based on an industrial robot. Experiments indicated that the new approach could ensure the thickness of adhesive layer among 100-150 m and effectively restrain the creation of air bubbles. The automatic system was tested to have high efficiency and reliability and it was going to make volume-produce.

“…Despite the significantly higher cost for III–V MJ cells based on GaAs, their dramatically higher performance and improved environmental stability resulted in an overall savings at the spacecraft level. Within a relatively short period of time, III–V MJ devices were the dominate solar cell used in orbit. , This trend has continued, and now virtually every spacecraft is powered by high efficiency III–V devices. Efficiency is also enabling for terrestrial applications of photovoltaics as increased efficiency reduces the balance-of-systems costs; thus III–V MJ technologies also dominate in terrestrial concentrator applications.…”

Photovoltaic energy conversion has demonstrated remarkable improvements in performance over the past 60 years. The rate of solar cell efficiency change has actually increased over the past 20 years as researchers have moved beyond elemental semiconductors to increasingly more sophisticated materials and devices. In addition, significant improvements in materials quality and deposition technology have further fueled this dramatic improvement in device performance. Diversifying from silicon to III−V compound semiconductor materials has enabled the development of multijunction solar cells with 3, 4, and even 6 subcells to achieve ever higher conversion efficiency. For 1-sun space application(s), these III−V multijunction cells are demonstrating ∼35% efficiency, while under terrestrial concentrated sunlight conditions efficiencies are >42%. This Article will discuss the development of high efficiency III−V multijunction solar cells, focusing on recently developed metamorphic device structures and novel lattice matched approaches.
