Study of the properties of printed graphene thin films

Prce je zamÄena na studium tenkch vrstev graf©nu, kter© mohou bt vyuity jako souÄsti fotovoltaickch Älnk. Tenk© vrstvy jsou pipravovny materilovm tiskem a nslednÄ charakterizovny pomoc­ optick© mikroskopie a UV-VIS. Na pipravench vzorc­ch byly promÄeny volt-amp©rov© charakteristiky a impedanÄn­ spektra a interpretovny jejich vsledky.The work is focused on the study of thin layers of graphene, which can be used as the part of photovoltaic cells. Thin layers are prepared by material print and subsequently characterized by optic microscopy and UV-VIS. Prepared samples were measured volt - ampere characteristics and impedance spectrum, and interpreted the results.
