Special Issue Information

Dear Colleagues,

Metal halide perovskites, in the form of both colloidal nanocrystals (NCs) and thin films, possess excellent optoelectronic properties, such as a high charge carrier mobility, excellent light absorption capability, tunable emission wavelength, narrow emission linewidth, and intrinsically high photoluminescence quantum yield. These advantages mean that perovskites can be used in wide color gamut light-emitting diodes (LEDs) with a good color purity and surpass the Shockley–Queisser limit and further boost the efficiency of tandem devices of solar cells.

This Special Issue will present research on the synthesis of perovskites and their application in LEDs and solar cells. We invite authors to contribute original research articles and review articles covering the current progress on high-efficiency and stable perovskite materials and their application in LEDs and solar cells. The potential topics include, but are not limited to:

the synthesis and shape modulation of perovskite NCs, defect chemistry on perovskite surfaces, the interfacial properties of perovskite with adjacent charge transport layers (CTL), the contact properties between CTL and CTL/electrodes, and the microscopic structure–property–performance relationship of devices.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nanomaterials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs).

In this work, guanidinium (GA+) was doped into methylammonium lead triiodide (MAPbI3) perovskite film to fabricate perovskite solar cells (PSCs). To determine the optimal formulation of the resulting guanidinium-doped MAPbI3 ((GA)x(MA)1−xPbI3) for the perovskite active layer in PSCs, the perovskite films with various GA+ doping concentrations, annealing temperatures, and thicknesses were systematically modulated and studied. The experimental results demonstrated a 400-nm-thick (GA)x(MA)1−xPbI3 film, with 5% GA+ doping and annealed at 90 °C for 20 min, provided optimal surface morphology and crystallinity. The PSCs configured with the optimal (GA)x(MA)1−xPbI3 perovskite active layer exhibited an open-circuit voltage of 0.891 V, a short-circuit current density of 24.21 mA/cm2, a fill factor of 73.1%, and a power conversion efficiency of 15.78%, respectively. Furthermore, the stability of PSCs featuring this optimized (GA)x(MA)1−xPbI3 perovskite active layer was significantly enhanced. Full article
