Polymer solar cells with enhanced open-circuit voltage and efficiency
Following the development of the bulk heterojunction1 structure, recent years have seen a dramatic improvement in the efficiency of polymer solar cells. Maximizing the open-circuit voltage in a low-bandgap polymer is one of the critical factors towards enabling high-efficiency solar cells. Study of the relation between open-circuit voltage and the energy levels of the donor/acceptor2 in bulk he...
متن کاملHigh Efficiency and High Open Circuit Voltage in Quasi 2D Perovskite Based Solar Cells
© 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim wileyonlinelibrary.com (1 of 7) 1604733 configuration is of the structure R2(CH3NH3)n–1MnX3n+1, where R is an organic group, M is a divalent metal, and X is a halide (Cl−, Br−, or I−). The number of perovskite layers are determined by the long organic groups separated by the MX6 layers.[8] In this work, quasi 2D perovskites were synthesized whic...
متن کاملUltra-high open-circuit voltage of perovskite solar cells induced by nucleation thermodynamics on rough substrates
To obtain high performance CH3NH3PbI3 perovskite solar cells, it is highly important to realise a high open-circuit voltage. Calculation results based on a modified diode model have indicated that a low bare ratio ϕ of the perovskite film is the most important factor determining the open-circuit voltage, where ϕ is defined as the ratio of the projection of the uncovered area of the perovskite f...
متن کاملA benzotrithiophene - based low band gap polymer for polymer solar cells with high open - circuit voltage †
novel electron-rich fused aromatic unit, namely benzo[1,2-b:3,4b’:5,6-d’’]trithiophene (BTT), which holds promise as a building block for semiconductor materials. In comparison with the wellknown benzo[1,2-b:4,5-b’]dithiophene (BDT), quantumchemical calculations (B3LYP/6-31G*) predict the BTT unit to 40 be of similar donor strength. Thus, with R being alkyl chains, BTT is predicted to act as a ...
متن کاملOpen-Circuit Voltage Physics in Amorphous Silicon Solar Cells
We have performed computer calculations to explore effects of the p/i interface on the opencircuit voltage in a-Si:H based pin solar cells. The principal conclusions are that interface limitation can occur for values of VOC significantly below the built-in potential VBI of a cell, and that the effects can be understood in terms of thermionic emission of electrons from the intrinsic layer into t...
