First Solar Achieves 22.1 Percent Efficiency With CdTe

Thin film record on research cell continues performance advancement trend

First Solar has established a record for CdTe photovoltaic (PV) research cell conversion efficiency, achieving 22.1 percent efficiency certified at the Newport Corporation's Technology and Applications Center (TAC) PV Lab.

The research cell was constructed at the company's Perrysburg, Ohio manufacturing factory and Research & Development Center using processes and materials suitable for commercial-scale manufacturing.

In addition to the Newport TAC Lab certification, the record has been documented in the US Department of Energy's National Renewable Energy Laboratory (NREL) "Best Research Cell Efficiencies" reference chart.

This is the ninth substantial update to CdTe record efficiency since 2011, according to the company, establishing a sustained trend of performance improvements.

"We are tracking very closely to a technology roadmap we first presented in 2013 and revised upward in March 2014," said Raffi Garabedian, First Solar's chief technology officer.

"At that time, we said we'd hit a 22 percent research cell efficiency milestone by the end of 2015. We've delivered on that promise. The accomplishment validates our continued confidence in CdTe as a superior PV material that combines cost effectiveness, reliability and high performance.

He added: "In recent years and based on our research cell progress, we've improved the efficiency and energy density of our mass produced commercial PV modules at a rate at least three times faster than our multi-crystalline Si competitors. We fully expect to further separate ourselves from the pack in coming years."

Garabedian noted that First Solar's lead manufacturing lines were producing PV modules with 16.4 percent conversion efficiency in 4Q 2015, and that the research cell efficiency accomplishment serves as a powerful driver for integrating performance improvement into the real-world manufacturing environment.



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.
