Stanford researchers have developed flat, ultrathin (sub 100nm) optical elements based on high index nanostructures which can be alternatives to refractive optical elements such as gratings, lenses, and axicons.
Stanford researchers in the Vuckovic group have fabricated thin-film 4H crystal structure Silicon Carbide with excellent quantum and classical photonics properties.
Researchers at Stanford have developed a technique that can rapidly and sequentially separate multiple sets of III-V solar cell thin films grown as a stack on one III-V wafer.
Stanford researchers in the Fan Lab have developed a photonic device optimizer that generates designs with hard geometric constraints to guarantee device fabricability.
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.
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 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.
