IQE & Solar Junction Aim To Boost Cell Efficiency To Over 50%

IQE has received a $1.95 million order for III-V solar wafers from the current world record cell efficiency holder, Solar Junction. The cash will be used for two purposes ; $1 million for first production wafers, and the remainder for the optimisation of Solar Junction's triple-junction indium gallium arsenide cells

IQE has received its first major orders for Concentrating PhotoVoltaic (CPV) wafers from CPV cell developer and manufacturer Solar Junction.

The orders are worth a total of $1.95 million, relating to $1 million for first production wafers and $950,000 for development wafers for improving yet further the efficiency of Solar Junction's CPV products. IQE signed a seven-year exclusive wafer supply agreement with Solar Junction in February 2012.

The CPV wafer production order follows Solar Junction’s recent announcement of its first 5MW order from SolFocus, which has been chosen as the system supplier for the 450MW project in Baja, Mexico, the largest CPV project announced to date, funded by Grupo Musa and Synergy Technologies LLC. CPV project announcements during 2012 are exceeding industry projections, with more than 650MW project announcements thus far.

Solar Junction currently holds the world record for CPV cell efficiency at 43.5% and, in conjunction with IQE’s proprietary internal wafer technology, aims to develop cell architectures with efficiencies of more than 50%. The cost of generating electricity using CPV in hot sunny areas such as California is already at cost parity with all other forms of power generation (source: GTM) and increasing cell efficiency will further lower the cost of CPV power generation substantially.

Drew Nelson, IQE President and CEO, says, “This order from Solar Junction is clear indication that CPV technology is gaining significant traction in large scale power generation projects in sunny areas. Our long term, exclusive wafer supply agreement with the world record holders in cell efficiency, coupled with the large scale manufacturing capacity now in place following our deal to acquire RFMD’s in-house MBE production capacity, position IQE to be a major wafer supplier to the rapidly emerging CPV industry, by far the most efficient of any solar technology."

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.
