Figure 28

The experimental dependence of the recombination efficiency 𝑍 on the diffusion coefficient ^0𝑥0𝐷^02𝑑𝑐 shown by triangles. The solid line was calculated theoretically, taking into account that the reorganization energy changes along with diffusion. The dashed line corresponds to the calculation with fixed but maximal 𝜆₀ reached at the fastest diffusion ^0𝑥0𝐷^02𝑑𝑐=1.072×10⁻⁵cm²/s. The dotted line was also calculated with a fixed but slowest diffusion ^0𝑥0𝐷^02𝑑𝑐=6.67×10⁻⁷cm²/s. From [102].
