Thin films for photovoltaics deposited by plasma chemistry methods\n
 Fejfar, Antonín
Thin films are key components for practically all of contemporary photovoltaic cells for solar energy utilization. Cells use thin films for optimizing light trapping, for selecting and collection of photogenerated charges and interface passivation or as absorber layers. Each year several hundreds of square kilometers of thin films are deposited mainly by plasma chemistry methods.

Chemical deposition of diamond thin films from gas vapors
 Kromka, Alexander
The preparation of diamond layers and their (nano-) structures requires the optimization of several technological steps. In the first step of “diamond technology” it is important to activate the surface of the non-diamond substrate by a suitable process known as nucleation or nucleation. The second key step is the growth of the diamond layer itself by chemical vapor deposition (CVD) under low pressures (10 ÷ 10,000 Pa) and temperatures in the range of 250 ÷ 1000 °C, and from a gas mixture of methane and hydrogen commonly used in a hot filament or microwave plasma CVD systems. In this paper, both technological steps, nucleation and growth, are discussed in light of current trends and experimental activities taking place in the laboratories of the Institute of Physics of the Academy of Sciences of the Czech Republic (FZÚ).
