Nanoscale innovation enhances Perovskite Solar Cell endurance

A recent study conducted by a group of scientists from the Massachusetts Institute of Technology and other institutions suggests that perovskite solar panels have the potential to enhance efficiency and durability over extended periods through the manipulation of the nanoscale structure of perovskite devices.

As indicated in a research article published in the journal Nature Energy, perovskites possess a unique crystal structure that could eventually surpass the performance of traditional silicon or cadmium telluride solar cells. One notable advantage is the solution-based processing of perovskites, allowing them to be applied like paint or print onto various surfaces such as flexible plastic, paper, or glass, making them adaptable and easily transportable.

Nevertheless, a significant challenge lies in the relatively brief operational lifespan of perovskite solar cells when compared to silicon, with perovskites breaking down in months rather than decades. Additionally, their efficiency slightly lags behind silicon when covering large areas.

The researchers propose that optimising the surface properties of perovskites through nanoscale surface engineering can effectively control defects responsible for energy losses, thus extending the operational life and enhancing efficiency.

According to Dane deQuilettes, a co-author of the paper, This paper is essentially revealing a guidebook for how to tune surfaces, where a lot of these defects are, to make sure that energy is not lost at surfaces. He added, This is the first paper that demonstrates how to systematically control and engineer surface fields in perovskites.

The crucial aspect involves the utilisation of a salt solution treatment to create an ultra-thin coating that passivates or modifies the defective surface layer of the perovskite crystal.

Maharashtra may allow higher FSI in Mumbai airport funnel zone

The Maharashtra government is considering the possibility of allowing higher potential Floor Space Index (FSI) for buildings located within Mumbai's airport funnel zone, in response to the redevelopment challenges caused by stringent height restrictions in these areas.The affected regions mainly include Vile Parle, Santacruz, and Kurla. As part of its revised policy for the funnel zone, the state government is, for the first time, offering Transfer of Development Rights (TDR) specifically for redevelopment purposes rather than for land acquisition.The issue was highlighted in the Assembly, whe..

Adani Ports, Airports May Raise $250 Mn from MUFG Amid US Scrutiny

Two entities under the Adani Group are in advanced negotiations to secure around $250 million in offshore bilateral loans from Mitsubishi UFJ Financial Group (MUFG), according to a Bloomberg report citing sources familiar with the matter.Adani Ports and Special Economic Zone is expected to raise approximately $100 million, while Adani Airport Holdings aims to secure about $150 million. The agreement related to the ports business could be finalised as early as this week. In addition to MUFG, both companies are also reportedly exploring funding options with other Japanese banks.This marks MUFGâ€..
