description | According to the present invention, provided are a photodiode using a metal-semiconductor structure which maintains photodiode characteristics thereof even after metal catalytic chemical etching, and has low-reflection and high-conductivity characteristics, a method for manufacturing the same, and a solar cell using the same. The photodiode of the present invention comprises: a semiconductor substrate having a low-reflective, high-conductivity surface having an electrode forming region to be selectively etched; and a high-conductivity electrode in which a metal catalyst used in a metal catalyst chemical etching process for forming an anti-reflection structure semiconductor substrate is positioned in an etched region of the anti-reflection structure semiconductor substrate. The photodiode of the present invention further comprises: a semiconductor substrate including an electrode forming region to be selectively etched and a light absorption region having a relatively protruding shape as compared to the electrode forming region; and an electrode including a metal catalyst layer positioned on the electrode forming region of the semiconductor substrate through chemical etching of the semiconductor substrate, and allowing a surface of the electrode forming region to have electrical conductivity.
