A new type of dye-sensitized solar cells (DSCs) based on nanoporous F:SnO2 electrode without TCO layer is fabricated by sol-gel combustion method for low-cost solar cell application. The TCO-less DSCs sample is composed of a glass/dye sensitized F:SnO2 layer/electrolyte/counter electrode. The samples have crystallite size ranging from 5 to 11 nm. The mean pore size of the sample is range of 15-28 nm. The preferred orientation indicates (1 1 0), (1 0 1), (2 1 1) for SnO2 and (2 0 0) for fluorine, respectively. The efficiency of prepared nanoporous F:SnO2 based TCO-less DSCs sample is about 1.2% (ff: 0.48, Voc: 0.61 V, Jsc: 6.75 mA/cm2). The sol-gel combustion method offers a simple and effective route for the synthesis of nanoporous F:SnO2 materials, and can be useful for DSCs application. © 2009 Elsevier B.V. Source

An apparatus and a method are provided for detecting and recording, in an electronic device, evidence of a persons situation. Situation data is detected using a situation data sensor in the electronic device. Situation data can be data representing evidence of a persons situation, wherein such evidence can show a persons place in relation to another person or thing, or the state of a person being able to interact with another person or thing. Next, biometric data of the user of the electronic device is detected. Biometric data can be data that represents one or more intrinsic physical or behavioral traits of a person. Thereafter, a report is created using the situation data and the biometric data, wherein the report includes evidence of the situation of the user of the electronic device.
