  • Photovoltaics International 27th Edition

    Now that the PV industry has unquestionably entered a new growth phase, all eyes are on which technologies will win through into the mainstream of PV manufacturing. PERC, n-type, p-type bifacial, heterojunction – all have become familiar terms in the ever-growing constellation of solar cell technologies. The question is which will offer manufacturers what they are looking for in improving efficiencies and cutting costs.

  • Manufacturing The Solar Future: The 2014 Production Annual

    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.
