EPJ Photovoltaics is an open access journal and so is freely and widely available to all readers via the Internet. Instead of paid subscriptions, the journal requires authors to pay an article-processing charge.
For these first years, EPJ Photovoltaics is pleased to offer a substantial discount to authors on the article-processing charges. For 2017 the promotional price is 300 Euros which covers a small fraction of the publishing costs.
The information for payment will be sent with proofs.
