摘要

The drive to develop clean, renewable sources of energy is in high demand with the world's growing dependence on fossil fuel as the primary energy source. Fossil fuel when burned, emit harmful by-products, greenhouse gas such as CO_2 which contributes to global warming, sulfur gases and mercury released from coal fired power plant are directly associated with acid rain, and acid mine drainage. The photoelectrochemical water splitting on the semiconductor electrode surface converting solar energy to hydrogen fuel offers an alternative energy solution which is clean and renewable (1). Progress in R&D on photo-electrochemical hydrogen generation is based on the development of new photo-active materials and photoelectrode fabrication. Oxide based semiconductors appear to be the most promising materials for water splitting using solar energy due to their long-term chemical stability, non toxicity, and relatively low cost processing technology. Moreover, their properties can be chemically modified by incorporating impurities such as H, N, S, C, and transition metals in their crystalline structures (2-9). Since the first publication on amorphous silicon (a-Si) relevant to the solar cell in the late 1960s (10), it has been studied as a promising material not only for electricity generation but also for water splitting to hydrogen and oxygen gases. Amorphous Silicon (a-Si) is cheaper than its crystalline form and the stacked triple-junction thin-film (nipipip) amorphous silicon (Tj-a-Si) generates higher photovoltage and photocurrent density. The a-Si cell also has a lower light induced degradation; however, it lacks stability in aqueous solutions. Different materials and
