Abstract

The power conversion efficiency of a polysilicon solar cell is nearly 20%, while that of an amorphous silicon solar cell exceeds 15%. However, as silicon material is inorganic, the simple fabrication of a flexible, lightweight and inexpensive inorganic solar cell is difficult. These limitations of inorganic materials have fuelled active study and considerable progress in the domain of organic thin film solar cells on a global scale. After a bulk-hetero junction structure was introduced in an organic thin film solar cell, one of the latter with power conversion efficiency exceeding 6% was reported. In this study, ethanol, a weak solvent, was added to the 0.01w%P3HT, the 0.01w%PCBM, and the mixed solution of the 0.01wt%P3HT respectively, all of which were dissolved in chloroform. From thin films fabricated by these solutions, P3HT grains and PCBM aggregations are observed with, and evaluated by AFM images and UV-vis spectra.
