Soitec CPV Cells Selected For Thirteen Solar Projects

The French firm's III-V Concentrix multi-junction cells will be used in power plants in France
Recently, the French Energy Regulatory Commission (CRE, Commission de Régulation de l’Energie) announced the winning bids of the second call for tenders from the French Energy Regulatory Commission (CRE, Commission de Régulation de l’Energie).

This was for the creation and operation of solar power plants with installed capacity of more than 250 kWc.

Soitec, a manufacturer of III-V and silicon semiconductor materials for electronics and energy, sees its concentrator photovoltaic (CPV) modules included in 80 percent of the projects selected.

Published in March 2013, the CRE’s second call for tenders calls for allocation of a volume of 20 MWc for ground plants exclusively based on CPV technology, plus a volume of 80 MWc for ground plants based on at least 50 percent on CPV, with a total minimum of 60 MWc allocated to CPV technology.

The sixteen projects finally selected further to this call for tenders represent a volume of 102.94 MWc. Thirteen of them (more than 80 percent) plan to use CPV modules manufactured by Soitec.

José Bériot, vice president of Solar Projects Development with Soitec’s Solar Energy division, explains: "Seeing our products present in a significant majority of the projects selected in this second call for tenders from the CRE is a great achievement for us. Overall, it represents a volume of more than 50 MWc for Soitec. This success is proof that our customers recognise the performance and reliability of our modules, and our ability to achieve profitability for future power plants."

Construction of the projects that have just been selected should be completed by spring of 2016, and the winning developers are now selecting the EPC contractors with whom they will partner on the construction sites.

Soitec's CPV technology uses III-V triple junction cells mounted on glass support plates. Fresnel lenses (manufactured using silicone on glass) concentrate sunlight five hundred times before it reaches these cells, which convert it into electricity.

A metal frame holds two glass plates to form highly robust, durable and resilient modules. By combining several modules on biaxial trackers (based on a proprietary algorithm automatically optimising their position based on the path of the sun), Soitec maximises energy generation throughout the day and its modules achieve a yield of 31.8 percent.

AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
