Abstract:

High efficient and cost-effective solar cells are of paramount importance to harvest abundant and clean solar energy. Among various techniques, solution processed solar cells have emerged as the promising candidates for the next generation of solar cells. In this talk, three types of solution processed solar cells, inorganic (quantum dot sensitized solar cells, copper zinc tin sulfide solar cells), organic (polymer, small molecule), and hybrid (dye sensitized solar cells, perovskite solar cell), will be discussed for their architectures and working principles. The management of the discrepancy between optical absorption scale (micrometer) and charge transport scale (nanometer) are crucial for the device efficiency. Common approaches adopted to address this problem through rational interface engineering will be delineated. At the last part of the talk, solar cells research carried out in FIU will be presented.
