20.500.12556/DKUM-80181 Uporaba sončne energije za polnjenje mobilnega telefona Using solar energy to charge a mobile phone Fotovoltaika je veda, ki proučuje neposredno pretvorbo svetlobe v elektriko. Izkoriščamo jo lahko v različne namene. V diplomski nalogi je izdelan sledilnik sonca z Arduino ploščo, ki je namenjen polnjenju mobilnega telefona. Naredili smo analizo v kolikšnem času se napolni baterija mobilnega telefona z našo sončno celico in ugotovili, da na hitrost in moč polnjenja vpliva veliko različnih dejavnikov kot so napetost, tok, moč sončne celice, tip telefona, letni čas in vpadni kot sončnih žarkov na celico. S pomočjo programa Matlab/Simulink sta izdelani I-U in P-U karakteristiki sončnih celic, ki sta uporabljeni v diplomski nalogi.Pri izdelavi I-U in P-U karakteristeke smo spreminjali dva okoljska vpliva na sončno celico in sicer gostoto sončnega sevanja ter temperaturo sončne celice. Photovoltaics is a science that studies the conversion of light into electricity and can be used for different purposes. In the diploma thesis, a sun tracker with an Arduino board is made for charging a mobile phone. We analyzed how long our solar cell charges the cell phone battery. The results showed that the charging speed and power are influenced by many different factors such as voltage, current, solar cell power, phone type, time of year, incident angles of sunlight on the cell. With the help of the Matlab & Simulink program, the I-U and P-U characteristics of the solar cells were made, which we used in our thesis. In the produced characteristics, we were changing the density of solar radiation and temperature of the solar cell. sončna celica Arduino Uno mobilni telefon sončni sledilnik I-U in P-U karakteristika sončne celice solar cell Arduino Uno mobile phone solar tracker I-U and P-U solar cell characteristics true true false [Z.
