2001-2002 – the local UNESCO expert in the international project TSP / UK / 0003/102 “Creation of the center for the use of solar energy in the city of Odessa.”
In 1998 (2 months), in 2002 (3 months), in 2003 (6 months), and in 2006 (5 months) – I was an intern in the “Physics of Thin films” group at the Swiss Institute of Technology (Zurich) under the guidance of prof. A. Tiwari. This group over the last 5 years holds the world record efficiency for flexible solar cells based on CdTe and CIGS. In 2006 the world record for flexible solar cells based on CdTe was obtained by Khripunov G.S. as evidenced by ref. [6] (please see below), and in accordance with ref. [5] and the international patent Hripunov G.S. is the co-creator of the world’s first right-sensitive film solar cells based on cadmium telluride.
