A new trade organization established by First Solar and rival CdTe thin-film module producers and suppliers has been formed to promote and educate on the technology’s attributes. Established as a non-profit organization under Belgian law, PVthin founding members include Abound Solar, Arendi, Calyxo, First Solar, GE Energy and 5N Plus. The first President of the PVThin is Andreas Wade, Director Sustainable Development at First Solar.

“The success of thin-film solar panels is one of the most exciting developments in solar energy in recent years,” commented Andreas Wade, President of PVthin. “PVthin was created to champion the role of thin-film PV and communicate the unique technological, environmental and socio-economic aspects of this cost effective and environmentally friendly solar technology. PVthin complements the excellent work of umbrella associations such as EPIA in Europe, SEIA in the US, and BSW in Germany and does not seek to create a rival organization.”

A website has been created by the group members, which has an initial emphasis on the environmental aspects, including LCA (Life Cycle Analysis) traits of using thin film, though defence of cadmium telluride-based modules is also evident.

Over the last few years there has been a campaign in Europe from some of its leading crystalline silicon module manufacturers, such as SolarWorld and REC to question the both the environmental and health and safety aspects of the CdTe-based modules. 

The newly formed group stressed that thin-film PV currently accounts for around 18% of global PV module sales, compared to almost zero a decade ago, while noting its low-cost advantages. However, in reality only First Solar has publicly demonstrated its low-cost leadership, while conventional crystalline silicon technologies have significantly closed the gap on First Solar over just the last few years.

As a consequence of falling polysilicon prices and massive capacity expansions, structural overcapacity has led to a solar shakeout which has impacted thin-film and crystalline firms as well as suppliers.

    Looking back, 2014 was a year of convalescence for a PV industry still battered and bruised from a period of ferocious competition. End-market demand continued apace, with analysts towards the end of 2014 predicting the year would see between around 45 and 50GW of deployment. That has begun to feed through to the supplier end of the market, with all the main manufacturers announcing capacity expansions in 2015 and further ahead.

    Although the past few years have proved extremely testing for PV equipment manufacturers, falling module prices have driven solar end-market demand to previously unseen levels. That demand is now starting to be felt by manufacturers, to the extent that leading companies are starting to talk about serious capacity expansions later this year and into 2015. This means that the next 12 months will be a critical period if companies throughout the supply chain are to take full advantage of the PV industry’s next growth phase.
