At present flat-panel modules, made of crystal silicon, form more than 90% of the total volume of solar elements (SEs) production. The forecast shows that in medium-term perspective there is no any alternative for using silicon.

Further increase in efficiency of PEC and power installations on their basis is connected with development and application of multitransition (cascade) SEs. Such elements have the extended range of spectral sensitivity in comparison with single-transition ones.

Recently this direction is especially intensively developed. Since 1996 two-cascade PECs on the basis of InGaP/GaAs are produced in the industrial scale. They were successfully applied in space. Industrial production of three-cascade PECs started in 1999 on the basis of InGaP/GaAs/Ge.

 Simplicity of creating half-conductive structure of SEs, low raw material consumption, application of cheap paddings, gaining of solid integral modules during the process of large-scale automatic production, significantly cheapens the process of thin-film (TF) FEM production

Photo-electric module of amorphous silicon (α-Si) is the thin-film SE of the complicated structure. The basis of its technological production process is the layerwise application of correspondent compounds of thin films by different methods.

Photo-electric installations (PEIs) became widespread in the world practice. They function in a system of autonomous and local power supply. In many countries well-known programs “solar roofs” are introduced. Under this name PEIs, mainly, in a form of flat PEMs, are meant, which are placed on roofs of buildings, including individual living houses. There were also many constructive solutions developed, the so-called “building integrated photovoltaic’, that is, PEMs in-built in construction, which are simultaneously its architecture-constructive units: parts of walls, roofs, screens.
