6 FAQs about [Solar cell complementarity]
Do organic solar cells with small molecule acceptors achieve high efficiencies?
Organic solar cells with small molecule acceptors achieve promising high efficiencies. The authors use numerical simulations to explain under which circumstances complementary absorption or overlapping absorption bands of the donor and non-fullerene acceptor molecules will be more beneficial for efficiency.
Why is a combination of complementary absorbing molecules more efficient?
Only when mobility and lifetime of charge carriers are sufficiently high to allow sufficient charge collection for layer thicknesses around the second interference maximum, a combination of complementary absorbing molecules is more efficient. For smaller thicknesses, a blend of molecules with the same absorption onset achieves higher efficiencies.
How do organic solar cells achieve high efficiencies?
For smaller thicknesses, a blend of molecules with the same absorption onset achieves higher efficiencies. Organic solar cells with small molecule acceptors achieve promising high efficiencies.
Is perylene diimide a suitable acceptor material for organic solar cells?
A potential perylene diimide dimer-based acceptor material for highly efficient solution-processed non-fullerene organic solar cells with 4.03% efficiency. Adv. Mater. 25, 5791–5797 (2013). Schwenn, P. E. et al. A small molecule non-fullerene electron acceptor for organic solar cells.
Is a fullerene a good acceptor molecule for organic solar cells?
While the process of exciton dissociation and charge generation in organic solar cells has frequently worked remarkably well 2, 3, 4, 5, 6 in the past, this was often—at least partly—due to the acceptor molecule being a fullerene. However, the predominance of fullerenes has been an obstacle for high performance.
What is the threshold for a blend with complementary absorption?
Thus, for a blend with complementary absorption the threshold for Q, above which thicker active layers are more efficient, is generally lower. Donor and non-fullerene acceptor molecules absorb only well in a limited spectral energy region of about ~0.5 eV.
