Princeton researchers see role for plastic electronics to reduce cost of solar cells in future. …
… "By allowing plastic solar cells to be manufactured using low-cost printing techniques and by replacing ITO as the primary
conducting material, the plastics the team developed hold potential for lowering the cost of solar panels. Currently, the electricity generated by plastic solar cells is collected by a transparent metal conductor made of ITO. The conductor must be transparent so that sunlight can pass through it to the materials in solar cells that absorb the light energy. " …
