Solar Cells and Modules Manufacturing Processes Research Laboratory
Experimental research of technological manufacturing processes of solar cells and modules. Implementing RTD activities non-contact laser techniques are used for formation of surface structures and development of high-efficiency solar cells of new structure. The laboratory staff is working on improvement of available solar cells production technological processes as well as on development of new processes with a focus on new laser processes. From the scientific and industrial viewpoint, laboratory using set of pulse power lasers – pulse duration from nanoseconds to femtoseconds – provides applied research and services ranging from formation of nanostructured surfaces to laser ablation of insulating layers and cutting wafers and solar cells.Experimental solar modules production facilities allow development of innovative bifacial, flexible and semi-flexible modules using innovative cells and materials.
