  • Reducing conversion losses and minimizing load via appliance level distributed storage
    Patent number: 10630099
    Abstract: Techniques, systems, and articles of manufacture for reducing conversion losses and minimizing load via appliance level distributed storage. A method includes identifying an alternating current power source associated with a direct current-powered device, determining a storage scheme for storing direct current power, converted from alternating current power input from the identified alternating current power source, in a local storage component associated with the direct current-powered device, and managing output of direct current power to the direct current-powered device based on the storage scheme and the identified alternating current power source.

  • Method to enhance the efficiency of dye sensitized and perovskite solar cell
    Patent number: 9576745
    Abstract: The present disclosure relates to a method to enhance the efficiency and reduce interfacial charge transfer resistance in dye sensitized solar cell (DSSC) and a perovskite solar cell (PSC) by fabricating with Mg and La doped photoanodes. Mg and La co-doped into TiO2 has shown more than 20% efficiency than pristine TiO2 and more than 5% higher efficiency than the single doping of 1% La and Mg in TiO2 cells. Thus, the present disclosure relates to an improved photoanode material to be used in solar cells.
