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 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.
Solar cells containing halide perovskite absorbers have shown large improvements in power conversion efficiency over the last eight years and now exceed 20%. This makes them competitive with many commercial technologies like polycrystalline silicon and CdTe.
Stanford researchers have for the first time, demonstrated the use of scaffolding to increase the mechanical and chemical stability of perovskite solar cells.
Stanford researchers have patented a crystalline germanium nanostructure device and method of forming a continuous polycrystalline Ge film (5-500nm thick poly-Ge) with crystalline Ge islands of preferred orientation.
Although organic thin film transistors (OTFTs) made from organic semiconductors are valued for their transparency, flexibility and low cost attributes, their sluggish response time due to slow carrier mobility limits their applications.
Stanford researchers have developed a simple and effective method to sort semiconducting from metallic single walled carbon nanotubes (SWNT). This scalable technique uses semiconducting polymers to wrap around individual semiconducting SWNTs dispersed in a solution.
Stanford researchers successfully purified highly enriched semiconducting single-walled carbon nanotubes (SWNT) free of any dispersing agent via an easy, fast and scalable method.
Stanford researchers have developed a versatile molecular engineering approach, via random copolymerization, to gain good processability while maintaining high charge transport and photovoltaic performance for conjugated copolymers.
Stanford researchers have developed and tested a new method of stably and strongly doping CNTs and graphene using MoOx as a nontoxic, inexpensive, vacuum or solution deposited alternative to strong liquid acids.
Researchers in Prof. Zhenan Bao's laboratory have invented a novel semiconducting material containing siloxane-containing side chains. This material demonstrates high charge carrier mobility, as well as air and operational stability in field effect transistor devices.
Stanford researchers are using nanowires (NWs) to raise the performance of organic solar cells. Organic solar cells' main weakness is their lack of efficiency compared to in-organic solar cells.
