solar factory
The goal of the Solar Factory project is implementation of new technology and launch of a high-efficiency thin-film PV module production line by applying and forming the CIGS layer using high-intensity light pulses.
PV technology (photovoltaic panels) has reached the level of readiness to revolutionize the power system, enabling consumers to produce energy for their own needs and discharge the surplus to the grid. Nevertheless, solutions that increase the efficiency of photovoltaic cells are still being sought. 2nd generation CIGS cells available on the market do not achieve 18% efficiency and module stability (90% efficiency after 10 years). The level of module efficiency is the main requirement and at the same time, a barrier to the market.
The implementation of Roltec technology will allow in the second half of 2022 to start the production of modules with an efficiency of 18%, with reduced production costs and stability of the standard modules (90% efficiency after 10 years) compared to the previously known and offered on the market.
The Roltec invention (patent application No. P.427122) concerns the improvement of the CIGS layer application technology using vacuum methods (evaporation method, magnetron sputtering and selenization / sulfurization)
SOLAR FACTORY Project in numbers:
The technological solution (invention) leads to a significant development of technology, including:
- Obtaining a better and controlled degree of crystallization of the CIGS layer — including control of the crystal composition in the growth phase.
- Obtaining a CIGS layer with lower roughness and larger grain size (crystal domains).
- Possibility of applying crystals of different composition (gradient cells) and high degree of crystallization.
- Thanks to the above, higher efficiencies of PV modules are obtained.
- Shortening the time of CIGS layer production (in-situ and post-treatment).
