Taastuvate energiaallikate kasutamine on järjest aktuaalsemaks muutuv teema.
Tänapäeval on hakanud päikeseenergia kasutamine end ära tasuma, kuna algselt
ebaefektiivsed elemendid. Käesoleva bakalaureusetöö käsitleb taastuvenergeetikat,
põhiline rõhk on suunatud päikeseenergeetikale. Lõputöö eesmärgiks on uurida, kuidas on
tehnoloogia areng ning nanotehnoloogia sissetoomine päikeseenergeetikasse seda
efektiivsemaks muutnud. Töös uuritakse päikesepaneele ning tuuakse välja võrdlused
2000nda aasta ja tänapäeva vahel. Võrdluste tegemiseks tehakse veebis leiduva kirjanduse
ülevaade ning tutvutakse erinevate andmebaaside varasemate uurimuste ning
aastaaruannetega. Töös tehakse kokkuvõtted, millised erinevused on aastatega tekkinud
tootlikkuses, hinnas ning efektiivsuses. Aastal 2000 oli päikesepaneelide paigaldatud
mahuks 0,65 GW, aastaks 2018 oli see number tõusnud 487,83 GW-ni. Esimesed
päikeseelemendid oli kasuteguriga 0,5% (1890ndad), aastal 2019 oli kasutegur juba kuni
30%. Paneelide kasuteguri tõus viis nende hinna languseni ning inimesed hakkasid neid
järjest rohkem paigaldama, kuna need on esimest korda ajaloos taskukohase hinnaga ja
tulusad. Ei osata öelda, millises vahemikus nanomaterjalid päikeseenergeetikas kasutusele
võeti, kuid andmeid on vähemalt 10 aasta kohta, nende mõju on dokumenteeritud.
Using renewable energy sources is becoming more and more common and profitable. This is because the initially inefficient solar cells have become more efficient by today. The given bachelor’s thesis deals with renewable energy, the main emphasis being on solar energy. The aim of the thesis is to study how the development of technology and the introduction of nanotechnology into solar energy have helped it improve. The thesis examines solar panels and compares the data from the year 2000 to the present day. To make comparisons, previous researches and annual reports from various databases are studied. In the given thesis the differences in electricity generation, price, and efficiency that have been created over the years will be summarized. In the year 2000, the installed capacity of solar panels was 0.65 GW, by 2018 that number had gone up to 487.83 GW. The first solar cells had an efficiency of 0.5 per cent (in the 1890s), in 2019 the efficiency was already around 30 per cent. The increase in efficiency of the panels led to a drop in the price, and people began to install them more and more since for the first time in history they have become affordable and over time will create profit. The first attempts to use nanomaterials in solar engineering are impossible to find, but data is available for at least 10 years, its effects have been documented.
