Abstract
Cost benefit analysis (CBA) and energy profit ratio (EPR) indicate that third generation PV should be high-throughput ones with higher efficiency than CdTe PV. The polymer photovoltaics (OPV) such as PCBM/P3HT, and the dye-sensitized solar cells (DSC), i.e. TiO2/dyes/iodide-iodine-electrolytes will be reviewed as printable PV to cope in near future with environmentally benign PV demand. The recent progress of OPV and DSC will be discussed in terms of diffusion length, and our recent studies on iodine-free DSC. The OPV-DSC-hybridized PV exemplified by solid-state Dye/TiO2/P3HT will become hopeful as printed thin-film solar cells, in particular when the conversion efficiency is further enhanced more than 10%.
