摘要

Researchers working on organic photovoltaic cells are confronted with the problem of finding the optimal thickness of the organic layers. Obviously, there is a competition between the absorption length of the incident light and the exciton diffusion length, leading to optimal film thicknesses lying somewhere between these two mean path lengths (D. Wöhrle, L. Kreienhoop and D. Schlettwein, PhthalocyaninesandRelatedMacrocyclesinOrganicPhotovoltaicJunctions, ed. C. C. Leznoff and A. B. P. Lever, VCH, New York, 1996). In this paper we investigate the general conditions for optimization of the thickness of the organic layer for a maximum photovoltaic yield. At normal absorption, the optimal layer thickness is typically 1.5 times the exciton diffusion length. As an application we consider the zinc phthalocyanine layer in an organic p–n cell, for which an exciton diffusion length of 30±10 nm is determined from simulations. Using this value, a good correlation between simulations and experiments is found with respect to the thickness-dependent photocurrent yield of the solar cells.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
