High 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 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...
متن کاملPolymer 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 کاملMechanism of carrier accumulation in perovskite thin-absorber solar cells.
Photovoltaic conversion requires two successive steps: accumulation of a photogenerated charge and charge separation. Determination of how and where charge accumulation is attained and how this accumulation can be identified is mandatory for understanding the performance of a photovoltaic device and for its further optimization. Here we analyse the mechanism of carrier accumulation in lead hali...
