Scientists have achieved a new world record for a next-generation solar cell, which holds the promise for novel applications like building-integrated and window solar panels. The breakthrough follows two years of research from the Hong Kong Polytechnic University into organic solar cells (OSCs), which until now have been too inefficient and costly to be used widely in practical applications. The research team invented a new technique to boost the stability of OSCs, achieving a power-conversion efficiency of 19.3 per cent. “The new finding will make OSC research an exciting field, and this will likely create tremendous opportunities in applications like portable electronics and building-integrated photovoltaics,” said Li Gang, a professor of energy conversion technology at Hong Kong Polytechnic University. “This is a very encouraging result for the long-standing research on OSCs that I have conducted over the past two decades. We have already achieved better OSC efficiency and this will subsequently help accelerate the applications of solar energy.” Professor Li and his team believe an efficiency rate above 20 per cent is now achievable using their new technique. The research is detailed in a study, titled ‘19.3% Binary Organic Solar Cell and Low Non-Radiative Recombination Enabled by Non-Monotonic Intermediate State Transition’, published in the scientific journal Nature Communications. The 19.3 per cent efficiency record is still a long way off other solar cell technologies, with researchers passing the 30 per cent barrier last year with a tandem design that used the so-called “miracle material” perovskite. OSCs are more lightweight and flexible than traditional silicon-based solar panels, as they consist of thin layers of organic semiconducting materials. The materials used are more environmentally friendly and 1,000-times thinner than silicon solar cells, meaning they have the potential to be vastly cheaper. They are also semi-transparent, allowing them to be used not just within building materials, but also on windows. Dozens of startups are already working on novel applications for harvesting solar energy, such as London-based Filia, which integrates solar technology into blackout blinds. California-based Ubiquitous Energy raised more than $30 million last year to push forward its vision of turning skyscrapers into “vertical solar farms” through the development of windows capable of converting sunlight into electricity. The firm aims to begin production at some point next year following further research and development.

Apple is to adopt a messaging standard that will make texting between an iPhone and an Android device a better experience. The US technology giant has confirmed it will adopt the rich communication services (RCS) “later next year”. RCS is considered an industry standard for messaging and allows users to send and receive high-quality photos and videos, chat over wifi as well as mobile data and users are able to see when messages have been read – a range of features that currently do not exist or work to the same standard when messaging between an iPhone and Android. Until now, Apple has focused on its own messaging system – iMessage – which allows for seamless communication between iPhone handsets. Later next year, we will be adding support for RCS Universal Profile, the standard as currently published by the GSM Association. We believe RCS Universal Profile will offer a better interoperability experience when compared to SMS or MMS Apple spokesperson Adopting RCS alongside iMessage will likely make the experience of chatting to an Android user from an iPhone closer to the iMessage experience. In a statement given to industry news site 9to5Mac, Apple said: “Later next year, we will be adding support for RCS Universal Profile, the standard as currently published by the GSM Association. “We believe RCS Universal Profile will offer a better interoperability experience when compared to SMS or MMS.” The announcement of the proposed change also comes as EU regulators have continued to pressure Apple to make iMessage more interoperable with other services under its new Digital Services Act – legislation designed to rein in tech giants, improve competition and ultimately provide better, more accessible services for consumers. Earlier this week, smartphone maker Nothing also revealed its Android phones would begin to support iMessage via a new app. Read More ICO seeks permission to appeal against Clearview AI tribunal ruling Users of iPhones can now check bank balance from Wallet app VR tool aims to help rail passengers spot and safely tackle sexual harassment

Nasa has released the most colourful picture of the universe ever made. The space agency created the image by combining data from the James Webb and Hubble space telescopes to capture light that has never been seen before in one image. The picture shows the galaxy cluster known as MACS0416, which is about 4.3 billion light years from Earth. The reds, blues and bright yellows of the picture represent one of the most comprehensive views of the universe ever taken, Nasa said. The colours represent the wavelengths of light captured, going from the shortest in blue to the longest in red. Those colours also help show the distances of those galaxies. Those galaxies that are closer and more active tend to be blue, while the red ones are further away – though some are also red because the vast amount of cosmic dust in the galaxy absorbs the blue of the light from stars. It was created by gathering both visible and infrared light captured by both telescopes. The original imagery was taken by Hubble in 2014, which captured some of the faintest and youngest galaxies ever detected, and it was then combined with Webb’s infrared data to look even further into the early universe. As well as making for a stunning image, researchers are already studying the data used to create it to examine the galaxy cluster and what it might mean for the universe as a whole. The Webb observations can be used to find “transients”, which are objects that change brightness over time. In the image there are some 14 transients – most of which are likely to be individual stars that are becoming brighter, with a minority that are thought to be supernovae. “We’re calling MACS0416 the Christmas Tree Galaxy Cluster, both because it’s so colorful and because of these flickering lights we find within it. We can see transients everywhere,” said Haojing Yan of the University of Missouri in Columbia, lead author of one paper describing the scientific results. One of them in particular is notable, and has been named Mothra. The object is being magnified by up to 4,000 by a process called gravitational lensing – and is notable because it was in both the new Webb images and the original Hubble ones. Scientists still don’t know how that could happen, since the alignment of galaxy clusters and stars needed to magnify something that much is delicate and would be expected to change. Scientists believe that the likely explanation is another unseen object that could be up to a million times bigger than our Sun and is unidentified. “The most likely explanation is a globular star cluster that’s too faint for Webb to see directly,” stated Jose Diego of the Instituto de Física de Cantabria in Spain, lead author of the paper detailing the finding. “But we don’t know the true nature of this additional lens yet.” The findings are detailed in two new papers, one to be published in The Astrophysical Journal and another that already appears in Astronomy & Astrophysics.
