RODOT
M i c h e l Rodot is "Directeur de Recherches" in the "Centre National de la Recherche Scientifique" (CNRS). W o r k i n g in the Bellevue laboratories in M e u d o n (France), he was the first, w i t h his l a b o r a t o r y d i r e c t o r Ch. Guillaud and his coworker H. Valdman, to o b t a i n high efficiency (14%) solar cells in France in 1970. An industrial development followed, by the company SAT, which p r o d u c e d spatial cells for fifteen years. In 1974 he launched with H . c u r i e n the first national R&D program on solar cells and in 1977 he h e l p e d W. Palz and R. Chabbal, responsible for the first EEC solar energy program, to define the p h o t o v o l t a i c part of this program. From 1976 to 1981 he left his laboratory to lead the CNRS p r o g r a m on solar energy, to which several hundreds of s c i e n t i s t s took part. Coming back in his Bellevue l a b o r a t o r y , he started a research p r o g r a m on p o l y c r y s t a l l i n e silicon solar cells, w h i c h was s u p p o r t e d by EEC since 1986. Together with R.Mertens (IMEC, Belgium), he obtained rather good (12% efficiency) epitaxial solar cells built on metallurgical grade silicon. This c o o p e r a t i o n continued, complemented by a p a r t i c i p a t i o n of the French c o m p a n y Photowatt, under the program "Multichess" of the E u r o p e a n Communities. Due to the work of coworkers like J.Nijs, J . C o p p y e and M . G h a n n a m in Belgium, Le Quang Nam, S . S i v o t h t h a m a n and D.Sarti in France, the efficiency of laboratory cells built on "Polix" polycrystalline silicon wafers was p r o g r e s s i v e l y raised to more than 16% (for 4 cm2 area). This international team d e f i n e d a v a r i e t y of paths to produce such cells, u s i n g w a f e r gettering, back surface field and emitter profiling. With h i g h l y doped w a f e r s and selective emitters, a world record of open circuit voltage was reached. With lowly doped wafers and h o m o g e n e o u s emitters, a process specially fitted to industrial u p s c a l i n g was designed, as presented in the A m s t e r d a m 1994 Conference, with a possible variant using RTA (rapid thermal annealing) as defined by the CNRS team of J . C . M ~ l l e r in Strasbourg

M.Rodot also worked on the diffusion of photovoltaic generators in the Third World. His a c h i e v e m e n t s w i t h V i e t n a m e s e colleagues were presented to the 2nd W o r l d R e n e w a b l e Congress in 1992. He is A d m i n i s t r a t o r of the " F o n d a t i o n Energies pour le Monde" (FONDEM), a French NGO which promotes solar rural e l e c t r i f i c a t i o n in Mali, Vietnam, Senegal and other countries. He organized many seminars on solar energy, in p a r t i c u l a r with: NATO, the Trieste school of physics, the EPS (European Physical Society), UNESCO, the IEPF (Institut de l'Energie des Pays Francophones), a G e r m a n - F r e n c h group, a F r e n c h - V i e t n a m e s e group and, above all, the European Communities. Twenty years after being in 1973 one of the organizers of the U N E S C O C o n f e r e n c e "Sun in the service of Mankind", he was in charge of the EEC :'Euroforum on renewable energies" in Paris (1993). He w r o t e more than i00 scientific papers, c o n t r i b u t e d to the journal "Systemes Solaires" oriented towards a large p u b l i c and was author or coauthor of four books: on S e m i c o n d u c t o r s in 1963, S o l a r Energy with A.Liebard and C.Philibert in 1992 (FONDEM sponsorship) and in 1993 Solar photovoltaic energy with B.Equer (UNESCO sponsorship) and Solar rural e l e c t r i f i c a t i o n with A . B e n a l l o u (IEPF sponsorship).
