Delivering an alternative to high-temperature solder processes, Henkel has developed Hysol Eccobond CA3556HF, a silver-filled electrically conductive adhesive designed to offer fast cure at low temperature. The material is also designed for high-throughput production processes and applications that dictate high peel strength, such as the assembly of PV modules.

Problem

While solder is arguably the most common electrical interconnect material, its high temperature requirements make it impractical for certain applications. Fragile, thin, temperature-sensitive substrates are often subject to damage not only from the requisite soldering temperatures, but also from screen and stencil printing processes themselves.

Solution

Initially designed to address the unique requirements of the photovoltaic module assembly market, Hysol Eccobond CA3556HF has been proven for other processes, too. Its flexibility for the photovoltaic sector is well-documented, as it is suitable for both crystalline-silicon and thin-film manufacturing. For c-Si cell production, the adhesive delivers an improved bond between the Ag and SnPbAg-coated tabs and the c-Si cells. Thin-film module manufacturers seeking a low-stress, fast-cure electrical interconnection of cells with ribbons have also incorporated the material into their processes.

Applications

PV module assembly for c-Si and thin-film applications.

Platform

The Hysol Eccobond CA3556HF includes high peel and shear strength, stress minimization properties to compensate for CTE mismatches, fast cure for high throughput and a no-mix, one-part formula which reduces operator error and speeds processing time.

EV World Congress

19 October 2021

This year’s EV World Congress will hold a special role, not only as the first live EverythingEV event in over a year – a chance to renew your connections and re-engage with the EV sector face to face – but also as a chance to share insight and inspiration as world starts to look towards move on post COVID towards hitting ambitious decarbonisation goals in 2030 and beyond. As ever, we will be bringing world leading organisations, cities, and technology providers to the UK to inspire EV innovators, and delve into the challenges facing the sector as the UK looks to revolutionise road transport.

An inverter’s role in delivering high availability and low LCOE for a new era of utility-scale solar

20 October 2021

Utility-scale solar is evolving, shaped by higher power modules and demand for increasingly lower levelised cost of electricity (LCOE). Those trends are also changing project requirements elsewhere, with inverters capable of delivering high power density and power capacity in strong demand. In this webinar, FIMER will detail how its innovative high-power, multi-MPPT string inverter and modular conversion solution can both meet those demands and transform the utility-scale solar sector for the better.

Global Race to Zero Summit 2021

20 October 2021

The race is on but we need to sprint… With global climate talks fast approaching and time running out to prevent the most disastrous impacts of climate change, now is the time to act. The Summit will explore the opportunities that emerge from taking action on climate change and provide a clear pathway forward for governments, citizens and companies. Taking place just 10 days before the G20 meeting in Rome, on 30-31 of October, and in the lead up to the critical COP26 meeting in Glasgow from 31 October–12 November, this event will be instrumental in influencing ambitious global action.

How simplistic tracker design can deliver competition-busting cost benefits

10 November 2021

The solar tracker market continues to mature at breakneck speed, with designs and component selections becoming ever-more complex in the pursuit of better project economics. But a more simplistic design could deliver a triple benefit of lower Capex, EPC and Opex costs. This webinar will set out the ideal single axis tracker design for utility-scale solar farms. The design leapfrogs from decades of experience, with a comprehensive understanding and attention to the three cost structures of Capex, EPC and Opx. Sun and Steel Solar has prototyped a single axis tracker designed to deliver up to US$0.03/W in real savings compared to existing single axis trackers on the market. That’s US$30 million for every gigawatt deployed.

Metallization and Interconnection Workshop

15 November 2021

The 10th edition of the famous Metallization and Interconnection Workshop, MIW2021, will take place in the Thor Central venue in Genk, Belgium, on Monday, November 15, and Tuesday, November 16, 2021 as a face-to-face meeting. We are longing for direct exchange of knowledge and ideas after a long time. Hopefully you can be part of it! But of course, the organizors will keep an eye on the evolution of the Covid pandemic. It will be assess carefully, whether the workshop can be held without major risks or excessive restrictions. We are looking forward to exciting talks, discussions and meetings and to welcoming you in Genk!

Solar & Storage Live 2021

23 November 2021

The solar, storage and EV industries in the UK are going from strength to strength. There is no better place for the community to meet, share ideas and do business than Solar & Storage Live from 23-25 November at the NEC.There’s something for everyone; more than 150 exhibitors, a high-level conference, a start up and innovation zone, a poster zone, strategic partners to network with and much more.
