NOVELTY - The solar cell comprises a glass substrate (1), a front electrode (2), a back electrode (3), a photovoltaic conversion layer (4), a light trapping layer (5), a stainless steel substrate, and an insulation layer. The back electrode is disposed at a position for enabling the front electrode to be arranged between the glass substrate and the back electrode. The photovoltaic conversion layer: is formed with a front surface and a back surface; and is disposed at the position between the front and back electrodes while enabling electromagnetic waves to incident through the front surface.    USE - Used as a solar cell.    ADVANTAGE - The solar cell can be economically, rapidly and simply manufactured with enhanced cell efficiency, high quality and reliability, increased mass production, good conductivity and reduced size, and is possible to greatly relieve the global warming crisis.    DETAILED DESCRIPTION - The solar cell comprises a glass substrate (1), a front electrode (2), a back electrode (3), a photovoltaic conversion layer (4), a light trapping layer (5), a stainless steel substrate, and an insulation layer. The back electrode is disposed at a position for enabling the front electrode to be arranged between the glass substrate and the back electrode. The photovoltaic conversion layer: is formed with a front surface and a back surface; is disposed at the position between the front and back electrodes while enabling electromagnetic waves to incident through the front surface and those electromagnetic waves that are not absorbed to be projected out of the same from the back surface so as to be used for absorbing the electromagnetic waves and for generating hole-electron pairs while transporting the holes to the front electrode; and comprises a p-type semiconductor layer, a n-type semiconductor layer, and an intrinsic semiconductor layer sandwiched between the p-type semiconductor layer and the n-type semiconductor layer. The light trapping layer has microballs, and is disposed at a position between the front surface of the photovoltaic conversion layer and the front electrode. A single layer of zinc oxide microball structure is formed from the composition of the zinc oxide microballs. A diameter of each of the zinc oxide microballs is 300-650 nm. The front electrode is disposed at the position for enabling the back electrode to be arranged between the stainless steel substrate and the front electrode. The insulation layer is disposed at the position between the stainless steel substrate and the back electrode of insulating the stainless steel substrate from the back electrode.
