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.

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.

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.
