Hybrid Solar Cells Versus Pure OPVs

Hybrid Solar Cells Versus Pure OPVs 

Research in the field of OPV based on small molecules or polymer/PCBM systems has developed tremendously within the past decade. Champion laboratory cells reaching efficiencies of 10% have been reported recently [132]. However, average solar cell efficiencies of optimized laboratory cells ranging in between 5 and 6% and PCE values of solar cell modules already commercially available on the market are usually lowered by a factor of about 2. 

The performance of NC-polymer hybrid solar cells increased constantly as well during the past years, but PCE values are still by a factor of 2 lower than that for pure OPV. Here, hybrid solar cell technologies benefit from the development of low-bandgap polymers from OPV, leading to an increased utilization of the incident solar radiation [81, 19]. However, the development of suitable low-bandgap polymers has been optimized for their utilization with fullerene-based acceptors such as PCPM and its derivatives, and the tailored design of polymers for specific
