|Increasing Organic Solar Cell Efficiency through Cell Structure Optimization|
|Keywords: Solar, Efficiency , Optimization|
|For solar power to become widely adopted the levelized cost of energy (LCOE) must be less than or equal to that of conventional sources. Through the use of low cost manufacturing techniques, inexpensive materials, and roll-to-roll (R2R) production the cost of solar modules can be decreased dramatically. However, before this technology can become a commercial solution work still must be done to increase the efficiency and longevity of these third generation solar cells By combining the strengths of dye-sensitized solar cells (DSSC) and organic photovoltaics (OPV) we investigate ways to improve the performance and stability of cells through a hybrid cell structure. The charge generation process is reviewed in detail and cell structure changes are evaluated with respect to their impact on each of the steps in the charge generation process. We investigate other ways to improve cell efficiency through modifications in heterojunction morphology as well as manipulation of various blocking layers with experimental support. Current – voltage (I-V) curves provide insight into charge carrier behavior within the cell and are used to explain the observed phenomena.|
