What is high-efficiency solar technology?

This high-efficiency solar technology takes advantage of inexpensive silicon wafers and provides a more robust design for next-generation solar cells in space. For terrestrial applications, it can provide unprecedented efficiencies for auxiliary power units in vehicles, solar roof tiles, power plants, and smart grid systems.

What technologies are used in high-efficiency solar cells?

To overcome these problems, many techniques have been investigated. This paper presents an overview of high-efficiency silicon solar cells' typical technologies, including surface passivation, anti-reflection coating, surface texturing, multi-junction solar cell, and interdigitated back contact solar cell.

Which solar cell has the best efficiency?

Recently LG Electronics has slightly exceeded this value with a GaAs concentrator solar cell having an efficiency of 29.3% (AM1.5d, 50 suns). With the same material Alta Devices realized a thin-film single-junction solar cell with an efficiency 28.8% under AM1.5g without concentration .

How efficient are silicon solar cells in the photovoltaic sector?

The photovoltaic sector is now led by silicon solar cells because of their well-established technology and relatively high efficiency. Currently, industrially made silicon solar modules have an efficiency between 16% and 22% (Anon (2023b)).

Why do solar cells have high efficiencies?

These high efficiencies are possible due to the ability of stacking solar cells made of different III–V semiconductors. The main focus of current research is on III–V multijunction solar cells with three or more junctions.

What is the efficiency of a triple-junction solar cell?

Recently a Ga 0.51 In 0.49 P/GaAs/Si triple-junction solar cell with an efficiency of 30.2 % AM1.5g has been published and 30.0% under 112x AM1.5d . These results show the high potential of III–V/Si tandem solar cells combining the high performance of the III–V multijunction cells with the low cost of silicon. 3.6.
