摘要：
A photovoltaic device forming a solar cell includes a first surface on a first column and a second surface on a second column, wherein the first surface is applied with a first light absorption media and the second surface is applied with a second light absorption media. The first surface and the second surface form a resonance cavity that can trap incident light entering to enhance light absorption.
