These light trapping solar cell structures increase optical absorption and carrier collection, improving efficiency by 24%, while significantly reducing the solar cell active layer thickness and thus lowering cost.
Stanford researchers at the Cui Lab have designed a self-aligned hybrid metal-dielectric surface that offers unparalleled performance in applications where both a transparent contact and a photon management texture are needed.
Stanford engineers have developed and tested a nanostructured thin film material that upconverts infrared to visible light and combines electrical and non-linear optical properties in the same layer.
Stanford researchers have discovered a novel method of doping nanowires (NW) and thin films (TF) that greatly improves surface area and performance. The sol-flame method is a fast, simple and low cost way to introduce dopants into NW and TF for a wide variety of applications.
Stanford researchers have disclosed a new family of white light emitting perovskites with photoluminescence quantum efficiencies (PLQEs) of up to 9%, which show stable emission over at least three months of continuous irradiation.
