1. A solar cell comprising:
- a support substrate;
a barrier layer on the support substrate; and
a photo-electro conversion part on the barrier layer,wherein the barrier layer comprises first and second barrier layers having porosities different from each other;
wherein the support substrate includes a flexible metallic substrate;
wherein the photo-electro conversion part includes a first electrode layer, a light absorbing layer, and a second electrode layer;
wherein the first and second barrier layers are in direct physical contact with each other;
wherein the second barrier layer is in direct physical contact with the first electrode layer;
wherein the first electrode layer includes at least one of molybdenum (Mo), copper (Cu), nickel (Ni), aluminum, and an alloy thereof;
wherein the porosity of the second barrier layer is higher than the porosity of the first barrier layer; and
wherein the porosity of the second barrier layer is in a range of 20% to 40%.
