“…Furthermore, it also forms an ohmic contact with the top contact layer of the cell boosting current collection efficiency (Kao et al, 2019). An anti-reflective coating (ARC) of silicon dioxide (SiO 2 ) and titanium dioxide (TiO 2 ) is deposited on the front surface to maximize absorption via reduction of reflective losses (Oh et al, 2020).…”

The ongoing energy transition to curb carbon dioxide emissions and meet the increasing energy demands have enhanced the need for integration of renewable energy into the existing electricity system. Solar energy has been gaining an increasing market share over the past decade. Multi-junction solar cells (MJSCs) enable the efficient conversion of sunlight to energy without being bound by the 33% limit as in the commercialized single junction silicon solar cells. III-V semiconductors have been used effectively in space applications and concentrated photovoltaics (CPV) over the past few decades. This review discusses the working and components of MJSCs at cell level as well as module level for space applications and CPV. The fabrication procedure, material acquirement of MJSCs is analyzed before introducing the current challenges preventing MJSCs from achieving widespread commercialization and the research direction in the future where these challenges can be addressed.

“…However, going beyond three steps is challenging because of the limited palette of optical materials with the required refractive indices and durability 5,9 . An elegant solution to this limitation, applicable to reach very low refractive indices, is to resort to nanoporous or mesoporous materials obtained by glancing angle deposition 1,10,11 . Another strategy is to use Herpin equivalents, 12 where a layer with the desired refractive index can be simulated by a symmetric three‐layer combination with the form HLH , H being a layer of a high index material and L being a layer of a low index material—with thickness calculated from Herpin equivalent equations using available refractive indices 12 —producing equal performance at only the design wavelength.…”

Antireflection coatings (ARCs) are crucial components of high-efficiency solar cells. A new ARC design philosophy, dubbed high-low refractive index stacks, has demonstrated good potential to minimize reflection losses for triple-junction and quadruplejunction solar cells in simulations. We have implemented such novel ARCs on GaInP/ InGaAs/Ge triple-junction solar cells and compared the experimental performancesexternal quantum efficiency and reflectivity-with that of identical devices equipping the classic double-layer ARC. For typical materials such as MgF 2 /ZnS with ambient glass, the results show that the new design improves the short circuit current by

“…This article will first briefly introduce the basic structure of multi-junction solar cells and some related knowledge. Afterwards, two methods to improve the conversion efficiency of multi-junction solar cells will be discussed detailly, one is to install anti reflective film [5] while the other is to improve the conversion efficiency by connecting multiple batteries in series. Subsequently, the characteristics of these two methods will be compared to analyze the pros and cons of each method.…”
