A fast, simple, and inexpensive method to fabricate in air, p-n diodes using electrospun tin oxide nanoribbons and regioregular poly(3-hexylthiophene) nanofibers is described. In addition to being a rectifier under ambient illumination or in the dark, the advantage of our design is the complete exposure of the rectifying nanojunction to the surrounding environment, making them attractive candidates in the potential fabrication of low power consumption diodes and sensors. The diode characteristics were analyzed using the standard diode equation and its use as a UV light sensor was examined.
