	<span><span style=\"font-family:Verdana;\">To fabricate a heterostructure solar cell using environmentally friendly materials and low cost techniques, tin oxide (SnO</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\">) and cuprous oxide (Cu</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\">O) were deposited by the sol-gel method and the electrochemical deposition, respectively. The SnO</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\"> films were deposited from a SnCl</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\"> solution containing ethanol and acetic acid. The Cu</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\">O films were depos</span></span><span><span style=\"font-family:Verdana;\">ited using a galvanostatic method from an aqueous bath containing CuSO</span><sub><span style=\"font-family:Verdana;\">4</span></sub><span style=\"font-family:Verdana;\"> and lactic acid at a temperature of 40¡ãC. The Cu</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\">O/SnO</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\"> heterostructure solar cells showed rectification and photovoltaic properties, and the best cell showed a con</span></span><span style=\"font-family:Verdana;\">version efficiency of 6.6</span><span> </span><span style=\"font-family:Verdana;\">¡Á</span><span> </span><span><span style=\"font-family:Verdana;\">10<sup>£­2</sup> </span><span style=\"font-family:Verdana;\">% with an open-circuit voltage of 0.29 V, a short-circuit current of 0.58 mA/cm</span><sup><span style=\"font-family:Verdana;\">2</span></sup><span style=\"font-family:Verdana;\">, and a fill factor of 0.39.</span></span><span></span>
