Impact of hole-transport layer materials on the field-induced degradation of p-i-n perovskite solar cells
The choice of hole-transport materials (HTMs) has a strong impact on electric field-induced degradation of perovskite solar cells (PSCs). Rational design of HTMs is necessary to make PSCs sufficiently stable for the targeted practical applications.
Paper
Measuring metal halide perovskite single cell degradation consistent with module-based conditions
Although a harsher condition, degradation of perovskite solar cells in an open-circuit condition is related to the performance in a quasi-maximum power point condition. Further, shadow masks should be used during illuminated stability studies.
Aging of quinoxaline-based polymer solar cells under UV-free white light
Photostability was tested on Qx-based organic solar cells with PCBM and ITIC acceptors. Accelerated aging experiments were carried out under UV-free white light. Direct contact between active and metal layers can degrade performance, rectifying Schottky contact in all blends and reducing device FF.
Towards the thermal stability of dye-sensitized solar cells for wavelength-selective greenhouses using the polymorphism of light-scattering layers
Long-term thermal stability of DSSC was firstly highlighted by exploring the photoanode polymorphism.
Promoting the stability of organic photovoltaics by planar heterojunction optimization
In organic photovoltaics (OPVs) with a bulk heterojunction (BHJ) active layer, the donor and acceptor materials have a metastable nanoscale phase mixture, where the uncontrollable morphology greatly reduces the stability of the device.
The water-dipping effect of branched poly(ethylene imine) interfacial layers on the performance and stability of polymer:nonfullerene solar cells
The water-dipping process can optimize the thickness of bPEI interlayers leading to improved power conversion efficiency and good shelf-lifetime in inverted-type polymer:nonfullerene solar cells.
Passivation mechanism of the perovskite upper interface based on MAPbBr3 quantum dots for efficient and stable perovskite solar cells
High quality perovskite films play a key role in efficient perovskite solar cells (PSCs).
Paper
An efficient approach for controlling the crystallization, strain, and defects of the perovskite film in hybrid perovskite solar cells through antisolvent engineering
Antisolvent engineering with the octylammonium salt OABr improves the quality of the perovskite film and suppresses nonradiative losses by 43.6%, resulting in high performance and stable inverted perovskite solar cells.
Paper
Understanding the role of interfacial layers in the photostability of PM6:Y7-based organic solar cells under different degradation conditions
At present, low long-term stability is the main limitation for organic solar cells. The origin of the degradation of high-efficiency non-fullerene solar cells by impedance spectroscopy and its degradation mechanisms has been investigated.
What defines the perovskite solar cell efficiency and stability: fullerene-based ETL structure or film morphology?
A study of fullerene derivatives as electron-transport materials for perovskite solar cells revealed that their crystal structures affect charge transport and device efficiency, while the operational stability is governed by the film uniformity.
Forty-two days in the SPA, building a stability parameter analyzer to probe degradation mechanisms in perovskite photovoltaic devices
Dunfield et al. discuss various options for satisfying the ISOS light stability series (ISOS-L-#) of tests, a homebuilt testing apparatus and software suite for such tests, and a case study.
