Main content of photovoltaic cell diffusion process
Exciton diffusion in organic photovoltaic cells
Exciton generation, migration, and dissociation are key processes that play a central role in the design and operation of many organic optoelectronic devices. In organic photovoltaic cells, charge generation often occurs only at an interface, forcing the exciton to migrate from the point of photogeneration i
Ion-implantation and photovoltaics efficiency: A review
The Ion-implantation technology gives efficient solar cells with lower cost and less number of stages of solar cell fabrication [24] ing a similar concept, Lanterne et al. [25] reported 18.5% high efficiency with only eight processing steps via implantation of boron and phosphorus in n-type solar cells.Lanterne et al. also found that with further …

Optimized phosphorus diffusion process and performance improvement of c-Si solar cell …
Phosphorus diffusion is the most common way to form the emitter for p-type crystalline silicon (c-Si) based solar cells. The emitter region is usually known as dead layer, which may result in the band gap narrowing and higher carrier recombination. In this work we have demonstrated that the SiP precipitates are usually formed in the emitter of …
