Singlet fission in tetracene generates two triplet excitons per absorbed photon. If these can be effectively transferred into silicon (Si), then additional photocurrent generated from photons above the bandgap of Si. This could alleviate thermalization loss and increase efficiency conventional Si solar cells. Here, we show that a change polymorphism deposited on due to air exposure facilitates transfer Magnetic field-dependent measurements confirm contribute photocurrent. The decay delayed...
Silicon solar cells are operating close to the theoretical maximum efficiency limit. To increase their beyond this limit, it is necessary decrease energy losses occurring for high-energy photons. A sensitizing layer of singlet-fission material can in principle double current generated by photons, and significantly reduce from photons within cell. Here, we construct a model such cell, using Si(111) surfaces tetracene. transfer between two layers, series tetracene derivatives was synthesized,...
SuFEx chemistry has recently evolved as next-generation click chemistry. However, in most syntheses, additional reagents/catalysts and carefully controlled conditions are still needed. Here, we aim to further generalize S(VI) exchange chemistry, using 4-nitrophenyl phenylmethanesulfonate example, which the nitrophenolate group is exchanged for a wide range of (substituted) phenols alkyl alcohols. Quantitative yields were reached within 10 min under ambient required only filtering through...
Silicon nanoparticles (Si NPs) are a good alternative to conventional heavy metal-containing quantum dots in many applications, due their low toxicity, cost, and the high natural abundance of starting material. Recently, much synthetic progress has been made, crystalline Si NPs can now be prepared matter hours. However, passivation these particles is still time-consuming difficult process, usually requiring temperatures and/or harsh reaction conditions. In this paper, we report an easy...
Sulfonamides have many important biological applications, yet their synthesis often involves long reaction times under dry and non-ambient conditions. Here we report the of a large range sulfonamides at room temperature using 4-nitrophenyl benzylsulfonate as starting material. were prepared from wide aliphatic, linear, cyclic amines, anilines,
