제목 | Influence of Window Layer Deposition Conditions on Characteristics of Cu2O Thin Film Solar Cells |
초록 | The broad use of photovoltaic energy as an infinite source of clean energy is still limited because of the high cost of power generation. Cuprous oxide (Cu2O), as a photovoltaic material, has a wide band gap of 2.17 eV. There are many reports on solar cells based on Cu2O as active layer because it has many interesting characteristics such as earth-abundance, 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, Cu2O absorber layer was deposited by electrodeposition. On top of it the buffer layer (ZnO) and the window layer (i-ZnO/AZO) was deposited by atomic layer deposition and rf-magnetron sputtering respectively. (Figure 1) We fabricated the cell with a change in i-ZnO layer thickness and the deposition temperature of the TCO layer. Finally, we compared the efficiency of the fabricated solar cells, and studied the influence of thickness of i-ZnO and TCO layer deposition temperature on the performance of Cu2O solar cell. |
