In this talk, we will review our recent progress using functional self-assemble monolayers (SAMs) to form dense assembly on metal oxide electrode (ITO for typical and TiO2 for inverted structure) as an interfacial layer for bulk heterojunction solar cell. With appropriate choice of SAMs, a significant improvement in parallel resistance and rectification can be achieved and leading to highly efficient devices. We also developed a series of low bandgap polymers and their performance as photovoltaic materials will be discussed. Finally, we will report on the material choices and processing conditions for all-solution processed tandem solar cells. A tandem cell composed of different sub-cells to harvest different portions of light in the solar spectrum have the potential to build highly efficient solar cell. Building such a device using solution processing remains a challenge as it involves processing issues of having robust layers that will not allow the dissolving or removing of the bottom layer during successive layer deposition. With the appropriate choice of materials, solvents and device geometries, our group has successfully built both types of tandem structures.
