Renewable Energy: Thin Film Co₃O₄/TiO₂ Heterojunction Solar Cells (Adv. Energy Mater. 1/2015)

Abstract

In article number 1401007, Assaf Y. Anderson, Arie Zaban, and co‐workers use combinatorial material science to develop an all oxide photovoltaic (PV) heterojunction consisting of anatase TiO2 and spinel Co3O4. This finding is a critical milestone in ongoing research towards all‐oxide photovoltaics, which hold the potential to become the most ecofriendly and cost‐effective renewable energy source.

Synthesis and Characterization of Cobalt Oxide Nanostructures. a Brief Review

“…Co 3 O 4 is a p-type antiferromagnetic oxide semiconductor with two band gaps and it is of great importance due to its optical, catalytic, and magnetic properties. The wide application areas of cobalt oxide nanostructures are known such as anode material in Li-ion rechargeable battery, catalyst, gas sensor, supercapacitor, electrochemical sensor, solar absorbing material, pH sensor, electrochromic devices, smart windows, photovoltaic devices, and magnetic materials [1][2][3][4][5][6][7][8][9][10][11]. Co 3 O 4 with a variety of morphologies such as wires, cubes, fibers, tubes, sheets, flowers, and hollow microspheres [12][13][14][15][16][17][18] have been reported in the literature.…”
