Purpose of the development: Thermodynamics of lateral epitaxial silicon layers designed for cheap solar cells, used in solar energy.

Recommended application field: Solar power.

Advantages over analogues: Novelty: Thermodynamic and computer modeling process of growing layers held in Ukraine for the first time. This method of solving the problem will be competitive.

The development stage readiness: Tested experimental exploitation order

Technical and economic effect: The economic attractiveness of development for market promotion , application and realization, parameters, price : Now search the growing conditions of these layers is carried out empirically. It requires a lot of time and material costs . Solve the problem proposed by theoretical methods using thermodynamic analysis and computer simulation of this multifactorial process . Thermodynamic analysis will develop computer programs that can rapidly and with a high probability to predict crystallization conditions for a desired substance . This approach leads to savings of expensive raw materials and reduce deployment time found by the crystallization conditions of the material in its manufacture .

Description of the development:
()
The essence of development : The limiting factor of modern solar energy should be considered a high cost of its main components - silicon cells . One of the promising ways to solve this problem is to improve the process and reduce the cost of their receipt. A thermodynamic model is proposed , which allows a high probability to predict technological conditions for growing silicon layers from the liquid phase rich in tin, by lateral epitaxy ( epitaxy on the partially covered with a mask substrates ) . Development relates to the field of modern semiconductor materials . State of readiness development : Developed thermodynamic concepts , describing the process of growing silicon layers by lateral epitaxy. The developed software solutions problem and obtain preliminary results. This part of the work published in the leading journals of the Russian Academy of Sciences and Ukrainian . Implementation Results : Preliminary results are applied when selecting conditions epitaxial layers ZHGTU (Ukraine) and the Technical University of Lublin (Poland) .
