| Popis: | 28th European Photovoltaic Solar Energy Conference and Exhibition; 2170-2174 Texturing of glass substrate is an interesting alternative to enhance light trapping in thin silicon solar cells instead of using conventional naturally textured transparent conducting oxides. In this work, aluminium induced texturing method is used to obtain borofloat glass substrates with rms values in the range 70 – 90 nm. Al-doped ZnO is deposited by sputtering onto textured glass to provide the front contact for thin film silicon solar cells. Morphology and optical properties of the textured glass substrates, as well as morphology, optical and electrical properties of the ZnO:Al layers deposited on them are described. The application of these textured substrates to a-Si solar cells is also presented. The use of this approach leads to devices with short-circuit currents similar to those obtained with optimized commercial TCO substrates. |
