Microcrystalline organic films with tunable thickness are produced directly on an indium-tin-oxide substrate, by crystallizing a thin amorphous rubrene film followed by its use as a template for subsequent homoepitaxial growth. These films, with exciton diffusion lengths exceeding 200 nm, produce solar cells with increasing photocurrents at thicknesses up to 400 nm with a fill factor >65%, demonstrating significant potential for microcrystalline organic electronic devices.
通过结晶一层薄的非晶态并五苯薄膜，然后将其用作后续同质外延生长的模板，在氧化铟锡（ITO）基底上直接生成具有可调厚度的微晶有机薄膜。这些薄膜具有超过 200nm 的激子扩散长度，在厚度高达 400nm 时，其太阳能电池的光电流不断增加，填充因子超过 65%，这表明微晶有机电子器件具有很大的潜力。
