제목 | Influence of Deposition Methods on Cu2O Thin Films' Characteristics |
초록 | Photovoltaic power generation as an infinite clean energy source is still below the widespread use because of power generation unit cost. Cu2O has large band gap of 2.17 eV. But, there are many reports on solar cells based on Cu2O as active layer because it shows many interesting characteristics such as earth-abundant, low cost, non-toxic, good mobility, and direct energy gap. The theoretical limit of the energy conversion efficiency of a Cu2O solar cell is 20%. In this work, we have investigated changes in the properties of materials by two different deposition methods which contains sputtering and electrodeposition. In the sputtering method, the films were deposited using both Cu and Cu2O targets according to substrate temperature, rf-power, and annealing condition. Also, in the electrodeposition, the samples are prepared to study dependence of film properties on pH, temperature of solution, and potential. Finally, we confirmed the structural properties of thin films by XRD and SEM. |
