CulnS_2 Solar Cells by Air-Stable Ink Rolling

摘要

Solution-based roll-to-roll deposition techniques are widely considered to be a route to low-cost, high-throughput electronic and energy device fabrication. The ink and the deposition method must be carefully designed to produce high-quality devices, such as solar cells. For solar cells, the deposition must be scalable, and the ink must be tuned to make dense, sufficiently thick layers without pinholes and with minimal residual contamination. Ideally, the solution should be air-stable and environmentally friendly. Various groups have reported the fabrication of photovoltaic devices using inorganic nanocrystal (NC) inks.
