Guidance for reporting
• Will appear published in http://cordis.europa.eu/fp7/find-doc_en.html. Following Annex II.4, we preview:
1. The consortium shall submit a periodic report to the Commission for each reporting period within 60 days after the end of each respective period. The reporting shall comprise:
a) an overview, including a publishable summary, of the progress of work towards the objectives of the project, including achievements and attainment of any milestones and deliverables identified in Annex I. This report should include the differences between work expected to be carried out in accordance with Annex I and that actually carried out
b) an explanation of the use of the resources (we plan to send a template)c) a financial statement, from each beneficiary together with a summary financial report consolidating
the claimed Community contribution of all the beneficiaries in an aggregate form, based on the information provided in Form C (Annex VI) by each beneficiary. (Can be downloaded from: http://www.ies-def.upm.es/ibpower/downloads/annex6cp_en.pdf)
• Audit certificate on finantial statments (every 375000 €) Annex VII Form D (Can be downloaded from http://www.ies-def.upm.es/ibpower/downloads/fp7-ga-annex7d_en.pdf).
• Audit certificate on methodology (requested by beneficiary and if Accepted by EC, there is no need to submit Audit Certificate on finantial statments) Annex VII Form E (Can be downloaded from http://www.ies-def.upm.es/ibpower/downloads/fp7-ga-annex7e_en.pdf).
Can we get Word versions for Annex VI and VII?

Semester Report Forms (internal forms)
• Let’s have a look to the form: link
• can be downloaded form www.ies-def.upm.es/ibpower http://www.ies-def.upm.es/ibpower/downloads/6monthsheet_IBPOWER_v10.doc
• serves to track publications• serves to collect presentations (mark as “confidential” confidential slides)• serves as check list for the meeting• reward: if you publish, only the presentation!

Reflection
• It is a project of Risk but also of oportunities, for example:
– Inplementing the IBSC with QDs and X-Metal IBSC application by themselves or in multistack systems.
– TF-IBSC.– All InGaN solar cell.
