| 제목 | ENHANCED PHOTOVOLTAIC PROPERTIES CUPROUS OXIDE BASED THIN FILMS SOLAR CELLS BY ELECTRODEPOSITION |
| 초록 | One of the goals of new photovoltaic cells implementation is to reduce the cost of energy generation to an amount that can be comparable to the conventional electric energy. This may be possible to achieve by photovoltaic devices that based on cheap materials and low-cost fabrication methods. In the last few years, the devices based entirely on metal oxides have been emerged as the promising alternatives. Among the different options, Cu2O its potential candidature due to non-toxic nature, earth abundant, high mobility, direct energy band gap (~2.1 eV) and cheap production. On the other hand, electrodeposition is a well-known technique for the synthesis of Cu2O thin films. Although it has been applied often for the fabrication of oxide solar cells, a systematic properties study of the Cu2O film with the deposition conditions has not been reported till date, especially in the context of photovoltaic applications. Furthermore, the performance has often been low and inconsistent for the solar cells that consist of electrodeposited Cu2O thin films. Thus, the main objective of this study is to optimize the properties of electrodeposited p-type Cu2O film for the solar cell applications. In this research, Cu2O films were deposited by electrodeposition method on Au/SiO2/Si and Pt/SiO2/Si substrates. We varied the pH of solution bath, potentials, and currents to find the optimal conditions for uniformed deposition of Cu2O thin film on each type of substrates. Thereafter, we investigated the performance of Cu2O solar cell on Pt/SiO2/Si substrate according to deposition parameter of the buffer layer and TCO layer. In the future works, we will investigate the effect of Au/SiO2/Si substrate on the performance of Cu2O solar cell. |
