Design of two-photon molecular tandem architectures for solar cells by ab initio theory.

An extensive database of spectroscopic properties of molecules from ab initio calculations is used to design molecular complexes for use in tandem solar cells that convert two photons into a single electron-hole pair, thereby increasing the output voltage while covering a wider spectral range. Three different architectures are considered: the first two involve a complex consisting of two dye mo...

The decay time constants shown in Table 3 have been fitted using exponential functions. The monoexponential fit of the S 0 and T 1 populations has been done using the following formula: P mono,S 0 /T 1 = 1 − e −t τ 1 (1) The biexponential fit has been performed using the following formula:
