Abstract
The organic thin fi lm solar cell has attracted considerable attention since a low cost solar cell fabricated by a printing process is expected. In this manuscript, a basis of the organic thin fi lm solar cell and the concept of power conversion effi ciency (PCE) enhancement are reviewed, and a printable thin fi lm solar cell based on a columnar liquid crystal showing high carrier mobility due to the self-organizing characteristics. In terms of the PCE improvement, the effectiveness of the surface plasmon resonance has been discussed.
