What Next for Singlet Fission in Photovoltaics? The Fate of Triplet and Triplet-Pair Excitons

Rohan J. Hudson et al.

Summary: This Perspective article summarizes recent progress in understanding the excitonic processes contributing to the decrease in efficiency in SF-sensitized PV devices. The inconsistent classification of triplet and triplet-pair excitons and the emerging design principles for improving the separability of triplet-pair excitons are discussed. The importance of considering anisotropic triplet-exciton diffusion in the design of SF-sensitized device architectures is demonstrated. Finally, recent advances in characterizing the processes of harvesting triplet-exciton energy are examined and prospective strategies for improving efficiencies in SF-sensitized PV devices are considered.

Shockley: Queisser detailed balance limit after 60 years

Tom Markvart

Summary: This article reviews the main results and developments of the Shockley-Queisser paper, discussing the detailed balance between incident and emitted photon beams and comparing its efficiency limit with other popular limits. The article also explores the impact of the generalized Planck law on the efficiency and current-voltage characteristic of the cell, and outlines a potential extension of the detailed balance into the realm of thermodynamics. Practical applications of the results in solar cell operation and mechanisms for exceeding the Shockley-Queisser limit are also briefly discussed.

Singlet fission photovoltaics: Progress and promising pathways

Alexander J. Baldacchino et al.

Summary: Singlet fission is a process in which a high-energy singlet exciton separates into two lower energy triplet excitons, with high quantum efficiency and potential for reducing energy losses in photovoltaic cells. Efforts have been made in the past decade to incorporate singlet fission into solar cells, comparing and categorizing various device structures to identify promising avenues for future research and development.

Revealing ultrafast relaxation dynamics in six-thiophene thin film and single crystal

Tongyu Zhao et al.

Summary: The excited state dynamics of six-thiophene (6T) thin film and single crystal differ under different excitation conditions, with the generation of ion pairs being the dominant process and triplet state lifetime being influenced by structural defects. Additionally, the competition between singlet fission and intramolecular vibrational relaxation in thin film and single crystal has implications for developing organic-molecule-based optoelectronic devices.

A simple generalization of the energy gap law for nonradiative processes

Seogjoo J. Jang

Summary: For over 50 years, the elegant energy gap law developed by Englman and Jortner has been a key theory for understanding the nonradiative transition rates in relation to the difference in energy between initial and final states. This study revisits the theory, clarifies key assumptions, and provides a generalization for cases where temperature dependence and low-frequency modes are significant. This generalized EG law shows significant improvement over the original law and is compared with stationary phase approximations for electron transfer theory.

Ultrafast spectroscopy reveals singlet fission, ionization and excimer formation in perylene film

Wenjun Ni et al.

Summary: Singlet exciton fission (SF) is a spin-allowed process that can enhance the efficiency of photovoltaic devices by creating two triplet excitons from one singlet exciton. The study of excited state dynamics in perylene film shows potential for high triplet formation quantum yield, singlet fission, and the competition of other relaxation channels. Exciton self-trapping by crystal lattice distortions within picoseconds highlights the simplicity and potential of perylene films in SF-based photovoltaic applications.

Temperature Tuning of Coherent Mixing between States Driving Singlet Fission in a Spiro-Fused Terrylenediimide Dimer

Xingang Zhao et al.

Summary: The excited-state dynamics of sTDI(2) were studied in toluene and mTHF at different temperatures. The results showed that temperature and static dielectric constant can directly control the composition of the electronically mixed excited state of sTDI(2) and thus the fate of the singlet fission process.

Realistic Efficiency Limits for Singlet-Fission Silicon Solar Cells

Benjamin Daiber et al.

Summary: Singlet fission is a carrier multiplication mechanism that can significantly increase the efficiency of silicon solar cells. The efficiency potential of singlet fission implementations in silicon solar cells varies depending on the transfer mechanism and singlet energy level. It is shown that the efficiency gain from singlet fission is greater for more efficient silicon base cells, unlike tandem perovskite-silicon solar cells.

Singlet fission from upper excited singlet states and polaron formation in rubrene film

Tong Wu et al.

Summary: Femtosecond fluorescence up-conversion and transient absorption pump-probe setups were used to study the relaxation dynamics of the lower and upper excited singlet electronic states in rubrene films, revealing accelerated singlet fission and polaron formation compared to the S-1 state. This finding could significantly expand the applications of rubrene in organic electronics and provide a new direction for synthesizing novel materials with optimized excited state properties for organic photovoltaic applications.
