1 Education in the field of photovoltaics in the Czech Republic Prof. Vitezslav Benda Department Electrotechnology Czech Technical University in Prague

2 Photovoltaics is one of the most dynamically growing industries at the present time World production The biggest PV market is in Europe The target 3 GW p will be reached in 2007, 6 GW p is expected in 2010 That will require people to be educated in photovoltaics Several tens of thousands of new jobs are likely to be created in the field of photovoltaics in the next five years

6 Czech Republic km 2, population: 10.3 millions

7 In Czech Republic Since 2005 after introducing feed-in tariff increased demand for PV system projects and realisation

8 ASPECTS OF EDUCATION IN PHOTOVOLTAICS Photovoltaics is a relatively very complicated subject. Understanding solar cell and solar modules function needs relatively broad knowledge from the field of:! material physics and technology! solar cell structure and technology both power and control electronics energy storage technology Some basic knowledge solar physics and meteorology are very important for proper system projection and realisation.

10 The education system in the Czech Republic non-compulsory pre-schooling 9-year primary schools 3 or 4 years of secondary education of various forms and types university studies - bachelor level - master level - PhD level Qualification courses for graduated

11 Propagation and basic information Sun to School programme Demonstration of PV for young generation and for the public Education tool Initiate a creation of research and development activities at universities Improving of experience with grid connection

12 200 W p systems at more than 600 primary schools 1.2 kw p systems at secondary schools at more than 40 secondary schools Education of teachers is very important

13 Program Powered by Sun There is yearly organized program for secondary school students and Czech championship called Powered by Sun. Participating students or teams study a photovoltaic system problems, build a simple small car robot powered by 1dm 2 photovoltaic panel and then adjust the parameters of control electronic to reach maximal speed of robot.

14 At 8 universities were built more power systems 1 3 kw p 6 20 kw p 2 40 kw p

15 Education in PV at universities Mostly, photovoltaics is mentioned in lectures on environmental problems Specialised courses on photovoltaic systems are organised at Czech Technical University in Prague, Faculty of Electrical Engineering since 1995 Since 2005 course on Photovoltaic systems forms part of the master study programme in Electrical Engineering and Information Technology at the CTU in Prague
