  • 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.
    Type: Grant

  • Macroporous ceramic body, method of manufacture and uses thereof
    Patent number: 9315425
    Abstract: The present embodiments disclosed herein are related to methods of preparing a macroporous ceramic body. According to some embodiments, a first mixture of ceramic-forming components is combined with a polymer network structure to form a second intermediate mixture comprising a polymer network. The polymer network is then removed in the drying and/or sintering step leaving an interconnected open pore network within the ceramic body. In some embodiments, the macroporous ceramic body comprises a three-dimensional, porous network comprising pores of about 3 mm to 11 mm.
