1. A transparent photovoltaic cell comprising:
a transparent substrate;
a plurality of micro-pillars arranged on an upper part of the transparent substrate and comprising respective transparent windows, through which incident sunlight transmits, on respective upper parts thereof; and
a photoelectric converter formed on an upper surface of the transparent substrate between the plurality of micro-pillars and on side surfaces of each micro-pillar, and configured to generate power through absorption of incident sunlight,
wherein the photoelectric converter comprises:
a transparent back electrode layer;
a light absorbing layer;
a transparent front electrode layer; and
a transparent insulating layer, wherein the light absorbing layer, the transparent front electrode layer, and the transparent insulating layer are sequentially laminated, and
wherein the transparent windows are configured to be formed by removing the light absorbing layer laminated on the upper parts of the plurality of micro-pillars.
