Abstract
V tem diplomskem delu smo izvedli nadgradnjo merilnega sistema za merjenje spektralnega odziva in kvantnega izkoristka optoelektronskih elementov. V prvem delu smo se osredotočili na teorijo, kar omogoča globlje razumevanje delovanja sistema. Opisali smo prevladujoča fizikalna modela svetlobe, uklon svetlobe in osnovne principe delovanja monokromatorja. V drugem delu naloge je opisan potek meritve pred in po nadgradnji z dvojnim žarkom, predstavljena je metoda lock-in, podani pa so tudi podrobnejši opisi uporabljenih merilnih inštrumentov ter nadgradnje krmilnega programa, implementiranega v programskem okolju LabVIEW. Zadnji del vsebuje ovrednotenje smiselnosti nadgradnje, podprto z razlago in analizo pridobljenih rezultatov. Delovanje sistema je bilo preizkušeno tudi z izvedbo praktičnih meritev.

Title:Integration of double beam in an optical system for measuring the spectral response and quantum efficiency of solar cells
Abstract:
Within this thesis we upgraded the measurement system for measuring the spectral responsivity and quantum efficiency of optoelectronic elements. In the first part we focused on theory, which enables a deeper understanding of the system functioning. The dominant physical models of light, light diffraction and the basic principles of the operation of the monochromator are all described. The second part of the paper describes the course of measurement before and after the double beam upgrade, the lock-in method is presented, and more detailed descriptions of the measuring instruments used and the upgrade of the LabVIEW control program are given. The last part contains an evaluation of the effectiveness of the upgrade, supported by the interpretation and analysis of the results obtained. The operation of the system was also tested by performing practical measurements.

Keywords:spectral responsivity, quantum efficiency, double beam, LabVIEW
