Screening-Engineered Field-Effect Solar Cells.

摘要

Photovoltaics (PV) are a promising source of clean renewable energy, but current technologies face a cost-to-efficiency trade-off that has slowed widespread implementation. We have developed a PV architecture--screening- engineered field-effect photovoltaics (SFPV)--that in principle enables fabrication of low-cost, high efficiency PV from virtually any semiconductor including the promising but hard-to-dope metal oxides, sulfides, and phosphides. Prototype SFPV devices have been constructed and are found to operate successfully in accord with model predictions.
