Stion`s CIGS Solar Modules Better Than Ever

The company's latest solar modules demonstrated no degradation in their first year

In April 2012, Stion installed a 60 kW demonstration array in Hattiesburg, Mississippi comprised of some of the very first CIGS modules produced at the company's high-volume factory in Mississippi.

After 1 year of field production in the hot and humid Mississippi delta, Stion’s modules showed zero degradation in power output. A random sample of modules was removed from the array and tested; they performed at or above the STC (an irradiance of 1000 W/m², an air mass of 1.5 and a module temperature of 25°C) flash test result that was recorded at time of production.

This may be a surprise to those in the solar industry that expect at least 1 to2 percent loss in power in just the first year with silicon-based modules.

This stable performance confirms that Stion’s modules match the stability seen in CIGS modules that have been stable for nearly 8 years in a test array at the National Renewable Energy Lab.

Stion’s CIGS modules have a dual glass / glass construction providing significantly improved moisture resistance and lifetime durability over the traditional polymer based backsheets used in traditional PV modules.

The firm's modules are resistant to potential induced degradation, light-induced degradation, and provide a durable solution engineered to survive in harsh environments and out-perform in non-ideal situations.

Stion COO Marty Finkbeiner says, “We at Stion are excited to offer a product line with improved laboratory performance and industry-leading technology that out-performs other technologies from day 1 to day 10,000."

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.
