Abstract
Although
organic photovoltaic (OPV) cells have many advantages, their performance still
lags far behind that of other photovoltaic platforms. A fundamental reason for
their low performance is the low charge mobility of organic materials, leading
to a limit on the active-layer thickness and efficient light absorption. In
this work, guided by a semi-empirical model analysis and using the tandem cell
strategy to overcome such issues, and taking advantage of the high diversity
and easily tunable band structure of organic materials, a record and certified
17.29% power conversion efficiency for a two-terminal monolithic
solution-processed tandem OPV is achieved.
