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.
