Micro/nanostructure pn junction diode array thin-film solar cell and method for fabricating the same

A method for fabricating a micro/nanostructure PN junction diode array thin-film solar cell comprising steps:

• providing a source-material wafer having a semiconductor micro/nanostructure array;
• coating a thin-film N-type semiconductor on a first transparent substrate;
• making said semiconductor micro/nanostructure array contact said thin-film N-type semiconductor of said first transparent substrate;
• fusing together said thin-film N-type semiconductor and one side of said semiconductor micro/nanostructure array;
• detaching said semiconductor micro/nanostructure array and transferring said semiconductor micro/nanostructure array to said first transparent substrate;
• coating a thin-film P-type semiconductor on a second transparent substrate;
• making said semiconductor micro/nanostructure array contact said thin-film P-type semiconductor of said second transparent substrate;
• and
• fusing together said thin-film P-type semiconductor and another side of said semiconductor micro/nanostructure array to form said micro/nanostructure PN junction diode array thin-film solar cell.
