More specifically, provided is a method for manufacturing a power generation element comprising a step of growing semiconductor nanowires on the surface of a substrate (Step 1); a step of forming a PVDF film by coating the substrate, on which the semiconductor nanowires are grown in the step 1, with a PVDF dissolved solution using a spraying method (Step 2); a step of separating the semiconductor nanowires and PVDF film from the substrate (Step 3); and a step of depositing a negative electrode part and a positive electrode part on one side of the semiconductor nanowires and PVDF film separated in the step 3 and on the other side opposite to one side (Step 4). The method for manufacturing the power generation element according to the present invention drastically improves power generation efficiency by modifying an existing manufacturing method, which manufactures power generation nanoelement using only nanowires or β-PVDF, and making a heterojunction based on the nanowires and the β-PVDF. Also, a power generation element can be manufactured by removing nanowires and then increasing the contact area of a β-PVDF film and an electrode. When a power generation element is manufactured with only β-PVDF, power generation efficiency also can be drastically increased. Further, carbon nanotubes (CNT) can be added to β-PVDF, and thus power generation efficiency of the power generation element can be enhanced. According to the contents of the CNT, transparency of the element can be easily controlled.
