The Fraunhofer PV Module Durability Initiative is seeking overcome the fact that current certification regimes give no indication of a module’s lifetime performance. The team behind the initiative describe its latest findings.
How silicon feedstock is packed into casting crucibles can have a big impact on the size and cost-efficiency of the resultant solar ingots. Til Bartel looks at some of the latest thinking around this essential stage in the PV manufacturing supply chain.
So far in 2015, Chinese domestic PV deployment has outstripped last year’s rates. A 20GW year would set a benchmark for China’s new five-year plan for solar development due to come into effect next year, writes Frank Haugwitz.
Last week the UN hosted the first of three crucially important global development conferences this year, culminating in the COP21 climate change talks in December. Reporting on the event, Alexander Lagaaij saw evidence of an appetite for cooperation, but still no high-level understanding of the potential of solar energy to put the world on a more sustainable path.
PV technologists often face the question of what the next-generation solar cell work-horse will look like. Radovan Kopecek and Joris Libal of ISC Konstanz offer some answers.
PV’s continued growth worldwide is creating fresh opportunities for investment in new and enlarged production facilities. But as Matthias Grossman writes, the costs and risks associated with entering new markets mean caution is required by investors.
As Europe seeks ways to impove the energy efficiency of its building stock, a key contributor to carbon emissions, building-integrated photovoltaics technology could offer some answers, writes Silke Krawietz.
As the political horse-trading over the future of the US solar investment tax credit gathers momentum, Laura Stern gives three good reasons why Congress should extend it.
As more and more distributed generation comes on to the grid, utilities will have to adapt their practices to accommodate it. Jacqueline Ashmore of Fraunhofer CSE looks at where the most action is needed as renewables become an increasingly unavoidable fact of life.
PV manufacturers are under increasing pressure to remove so-called conflict materials from their supply chains. But as Chris Berry explains, it’s not quite as simple as that.
As Intersolar Europe prepares to open its doors in Munich next week, James Watson, CEO of Europe’s main solar industry body, explans why 30 years into its lifetime, the organisation has rebranded to better reflect PV’s changing dynamics in the continent.
Radovan Kopecek and Joris Libal explore the prospects for producing new cell and module technologies in territories outside of the big manufacturing countries.
Frank Haugwitz explores the opportunities for China’s solar industry at home abroad as the country’s new five-year solar development plan is finalised and manufacturers look to expand their global footprint.
With the spectre of trade disputes showing no signs of going away, Asian PV manufacturers need to develop effective strategies to cope with future anti-dumping and anti-subsidy investigations, says Matthias Grossman.
If India were to grow its electricity system based on coal as China has done, the results for the global climate could be catastrophic. Tobias Engelmeier believes this leaves the country with little choice but to go solar.
An extension and gradual phase out of the investment tax credit would help the US solar industry on to a more sustainable footing in the long term, argues James A. Mueller
Growing awareness of the advantages of using controlled quantities of impurities in solar silicon is closing the price gap between lower and higher purity feedstock, writes Til Bartel.
A lax management and maintenance regime can see the value of a PV system leach away over time. Laura Stern outlines some of the key steps in ensuring a system retains its value right up to the end of its planned lifetime.
With potential induced degradation emerging as a major issue for PV power plant performance, manufacturers have responded by developing technologies to mitigate the problem. But a lack of long-term field data on PID means the jury is still out on whether these efforts will be sufficient, writes Rubina Singh of Fraunhofer CSE.
Earlier this week market research firm IHS issued revised figures for global PV installs in 2014 and confirmed its 2015 guidance at 57GW. Ahead of a webinar to be jointly hosted with PV Tech on Wednesday 15 April, IHS’ senior analyst, Susanne von Aichberger, and senior director, Ash Sharma, answer some questions on the key PV trends for 2015.
Last week Chinese authorities announced a 17.8GW PV target for 2015, an even more ambitious quota than the one set in 2014, which was missed. Beijing-based Chinese solar market expert, Frank Haugwitz, asks whether China can live up to its aspirations this time around.
Despite the promise it offers of higher efficiencies, n-type solar cell technology enjoys only limited market penetration. Radovan Kopecek and Joris Libal of ISC Konstanz explain why and look at its prospects for growth.
In an exclusive blog post for PV Tech, solar entrepreneur and campaigner Jeremy Leggett spells out why the time has come for the solar industry worldwide to fight back against the lobbying tactics employed by the fossil fuel industry.
Matthias Grossman analyses the prospects for a wave of expansions in the dynamic polysilicon market.
Optimism is growing that the Paris COP 21 meeting set for November and December 2015 could lead to an international agreement to limit CO2 emissions. James Watson, CEO of the European Photovoltaic Industry Association (EPIA), explains why a successful outcome would be a boon for the solar industry.
