Heterojunction technology for novel silicon-based solar cells

The application of heterojunction technology to novel silicon-based solar and photovoltaic cells is reviewed. The performance of mono-crystalline as well as thin-film silicon solar cells based on heterojunction technology is discussed in detail. Moreover, the shortcomings and current problems that need further improvement are critically addressed. We conclude by reviewing the future prospects of these new heterojunction structure silicon-based solar cells.
