Scaling up high-performance perovskite solar cells (PSCs) while avoiding losses in the power conversion efficiency (PCE) is a challenging task. Deposition of high quality large …
Solar cells grew out of the 1839 discovery of the photovoltaic effect by French physicist A. E. Becquerel. However, it was not until 1883 that the first solar cell was built by Charles Fritts, who coated the semiconductor selenium with an extremely thin layer of gold to form the junctions.
Popular Science reporter Andrew Paul writes that MIT researchers have developed a new ultra-thin solar cell that is one-hundredth the weight of conventional panels and could transform almost any surface into a power generator. The new material could potentially generate, "18 times more power-per-kilogram compared to traditional …
1. Introduction. Recently, it has been shown that photoluminescence (PL) imaging is an efficient tool for wafer quality control of mc-Si [1], [2], [3] and Cz-Si [4] as-cut wafers. The method can be used to detect material defects in as-cut wafers during incoming quality control before solar cell production, which allows rejecting wafers with too low …
The PCEs of the large-area perovskite solar cells made by scalable deposition techniques, however, are typically lower. One frequent element to improving performance in perovskites has been the utilization …
Perovskite solar cells (PSCs) are the most rapidly advancing photovoltaic technology in terms of power conversion efficiency. An efficiency of 26.1% was achieved in a decade, which is on par with the efficiency of very mature silicon panels. However, PSC commercialisation is partly hindered by the difficulty of scaling these devices without …
The real exploitation at the market level of PVSK PV technology can be feasible only if the laboratory cells (area ˂1 cm 2) results will be transferred to mini (area ˂200 cm 2) and sub-module devices (200 cm 2 ≤ area ≤ 800 cm 2). 1, 5-7 A module device is composed of a number of sub-cells connected in series to overcome the non-negligible ...

such as those used in the fabrication of perovskite solar cells. For the fabrication of organic photovoltaics, using inks with similar properties to those of perovskite solar cells, Krebs [10.] introduced the use of a meniscus guide as part of the coating head, to help control the formation of the meniscus at low coating speeds. The meniscus guide

The efficiency gap between perovskite (PVSK) solar sub-modules (size ≥200 cm 2) and lab scale cells (size ˂1 cm 2) is up to 36%.Moreover, the few attempts present in the literature used lab-scale techniques in a glove-box environment, reducing its compatibility for further product industrialization.
Slot-die coating (SDC) has become a great method for fabricating large-area perovskite solar cells and modules due to controllable film thickness, high solution utilization rate, wide solution viscosity range and fast response speed. During the coating process, solvent properties play important roles in the formation of perovskite films, …
