The international Energy Agency (IEA) founded in November 1974, is an autonomous body V`k8j-*s
within the framework of the Organisation for Economic Co-operation and Development G9RP^
(OECD) which carries out a comprehensive programme of energy co-operation among its 23 C4NRDwU |.

The IEA PhotoVoltaic Power Systems Programme (PVPS) is one of the collaborative R&D
Oh`2tc-
agreements established within the IEA, and since 1993, its Participants have been conducting a mP-2s;q
variety of joint projects in the applications of Photovoltaic conversion of solar energy into h\y-L~2E
electricity. FT/amCRyT
The Overall programme is headed by an Executive Committee composed of one representative CLN+I'uX0
from each participating country, while the management of individual research projects (Tasks) M !{'ED
is the responsibility of Operating Agents. Currently nine Tasks have been established in the m;/i<:`
