| Combining the two key factors of high performance and low cost into a single solar cell is the major challenge of research on photovoltaics. It is not easy to conceive a practical approach to such a device if not based on thin-film technology. Yet, it appears equally clear that current thin-film solar cells must upgrade their performance by some means in order to meet satisfactory energy conversion efficiencies. The incorporation of novel photovoltaic concepts, with potential to surpass the Shockley-Queisser fundamental limit of single-gap photovoltaic devices, into thin-film technologies is expected to cross-fertilize both fields. In this presentation the potential benefits of a thin-film intermediate band solar cell (TF-IBSC) will be outlined and two different approaches toward its practical implementation based on chalcopyrite absorbers will be presented, with particular emphasis on nanostructured material. A brief discussion of photoreflectance as a suitable tool for the optoelectronic characterization of advanced photovoltaic structures will also be included. | |
