Researchers have developed a new method to implement different types of nanowires side-by-side into a single array on a single substrate. The new technique makes it possible to use different semiconductor materials for the different types of nanowires.
Over the last decade the industry has witnessed the growth of crystalline Si based photovoltaics at the expense of thin-film technologies. This has led many to rethink the opportunities offered by thin-film photovoltaics and the technological needs to serve specific markets like building-integrated photovoltaics where thin-film photovoltaics would offer unique opportunities. What are the requirements to integrate photovoltaics in the built environment and what are the consequences this vision has on research and development strategy in the field of thin-film photovoltaics?
