Solar Cells: An Optimal Harvest

IME researchers have demonstrated for the first time that low-grade Si materials enhanced with nanostructures may be just as effective as expensive high quality bulk Si to attain good power conversion efficiency for solar cells production. Results from this study are likely to be warmly received by green activists and the general public alike, as they can look forward to accessible solar energy options; conventional solar cells made with expensive high bulk Si have made the attractive solar energy option a far-fetched reality for many. Findings from this work provide a practical guideline to design and produce highly efficient Si thin film solar cells.
