Cu 2ZnSnS 4 (CZTS) thin films were deposited onto Mo-coated and tin-doped indium oxide (ITO) coated glass substrates by using single step electrodeposition technique followed by annealing in N 2 + H 2S atmosphere. Subsequently, they were applied to the fabrication of thin film solar cells. Upon annealing, the amorphous nature of as-deposited precursor film changes into polycrystalline kesterite crystal structure with uniform and densely packed surface morphology. Energy dispersive X-ray spectroscopy (EDS) study reveals that the deposited thin films are nearly stoichiometric. Optical absorption study shows the band gap energy of as-deposited CZTS thin films is 2.7 eV whereas, after annealing, it is found to be 1.53 eV. The solar cell fabricated with CZTS absorber layer, showed the best conversion efficiency (ι) 1.21% for 0.44 cm 2 with open-circuit voltage (V oc) = 315 mV, short-circuit current density (J sc) = 12.27 mA/cm 2 and fill factor (FF) = 0.31. © 2012 The Japan Society of Applied Physics.

Investigation towards the performance of room temperature (27 °C) liquefied petroleum gas (LPG) sensor based on the heterojunction between p-PEDOT:PSS and n-type ZnO is reported. The junction was developed by using chemically deposited ZnO film on to fluorine doped tin oxide (FTO) coated glass substrate followed by coating of thin slurry layer of PEDOT:PSS by using spin coating technique. Both these methods are simple, inexpensive and suitable for large area applications. Different characterization techniques were used to characterize structural, surface morphological and compositional of the material deposited. LPG sensing behavior of the heterojunction was studied at room temperature along with the stability studies. At room temperature, the heterojunction showed 58.8% sensitivity upon exposure to 1000 ppm of LPG with good response and recovery time like 225 s and 190 s, respectively. Furthermore, the LPG sensor reported is cost-effective, user friendly, and easy to fabricate using low cost chemical methods at room temperature. © 2011 Elsevier B.V. All rights reserved.


A system and method for recorded renewable energy certificates from power produced by small power generators is provided. An appliance can include a renewable energy source and electronics to monitor and control the charging of batteries in the appliance utilizing power from the renewable energy source. Power from the batteries can be utilized to power or charge external devices. The electronics also records the total power production from the renewable energy source and uploads transaction records to either an external device for transmission to a records server or uploads it directly to the records server itself The records server compiles the transaction records and generates renewable energy certificates by aggregating the transaction records. Renewable energy certificates can be redeemed in exchange for real or virtual goods and services.

Solar Components, a company that makes portable solar chargers, has raised $2.8 million of an expected $4.9 million in equity, according to a filing with the SEC. Based in Campbell, Calif., the startup makes a waterproof device, called the JOOS Orange, that it claims can power four smartphones on a single charge. The device, which costs $99.95, can be used to charge portable electronics like cell phones, iPads and digital cameras, but the company also suggests that the JOOS Orange can be used to charge low-wattage heaters, small medical refrigerators and water purification systems. The charger can be powered by the sun or any USB source such as a laptop, and though the chargers are not yet available for sale, the company announced in late September that the units are in production.
