Abstract

Research on new materials for solar energy is a very important area for future energy systems. The use of solar power does not damage the environment and hence will not contribute to global warming. Solar energy is one of the most important renewable sources of energy and can be used cleanly and widely whenever the technologies are developed. The solar cell converts sunlight into electrical energy that can be used to power domestic devices. It should be noted, the sun's energy provides 1.34 × 1031 J per day, which can satisfy the world's energy requirements for a year. Researching new materials for solar cells is vital to continued innovation in the area of PV technology. The most common solar cell type is a Si based p (base) – n (emitter) junction solar cell; the most widely used today. Finding new materials for the emitter that can lower cost while improving the performance is now an important research area. In research for the present work ZnO based cells, the JV dark curve, JV curve under illumination, EQE, reflectance and IQE are studied. The JV dark curve shows a working p-n junction diode. The maximum EQE is 20.83% at 530 nm and the maximum IQE is 28.42% at 490 nm. Therefore, the purpose of this thesis is to use ALD grown ZnO as the emitter of the Si solar cells.
