Enhancing a Record-Breaking Perovskite/Silicon Tandem Solar Cell

Image Credit: Morakot Kawinchan/Shutterstock.com Several years of rapid development has allowed research groups worldwide to create increasingly efficient perovskite/silicon tandem solar cells. The scientific focus is now shifting towards the better understanding and control of the mechanisms responsible for the impressive performance of these new types of photovoltaics. Solar cells based on crystalline silicon have been very successful during the worldwide uptake of photovoltaic (PV) technology and currently dominate the PV market. The vast majority of the commercial solar cells used in solar power plants are of the single-junction type and generate electricity using the single p-n junction.

Perovskite/Silicon Tandem Solar Cells on Threshold of 30% Efficiency

An HZB team has published a report in the journal Science on the development of its current world record of 29.15% efficiency for a tandem solar cell made of perovskite and silicon. The tandem cell provided stable performance for 300 hours - even without encapsulation. To accomplish this, the group headed by Prof. Steve Albrecht investigated physical processes at the interfaces to improve the transport of the charge carriers.   Solar cells consisting of two semiconductors with differing band gaps can achieve considerably higher efficiencies when used in tandem compared to the individual cells on their own. This is because tandem cells use the solar spectrum more efficiently. In particular, conventional silicon solar cells primarily convert the infrared components of light efficiently into electrical energy, while certain perovskite compounds can effectively utilise the visible components of sunlight, making this a powerful combination.

Road-rage incidents could be driven by pandemic: expert

Road-rage incidents could be driven by pandemic: expert Winnipeg woman recalls harrowing commute in online post Last Modified: 6:25 AM CST Tuesday, Dec. 22, 2020 | Updates As if driving through a Winnipeg winter isn’t bad enough. As if driving through a Winnipeg winter isn’t bad enough. An American road-rage expert says bottled-up frustration over the pandemic and the effect it’s having on the holiday season could have played a role in a couple of notable incidents on Winnipeg streets over the past few days. The hydro pole was hit by a vehicle after two drivers got into an argument about 4 a.m. on Monday, police say. (Mikaela MacKenzie / Winnipeg Free Press)

German researchers pip Australian lab to set new next-gen solar panel efficiency record

16 December 2020 A team of European scientists have claimed a new world record for solar energy conversion efficiency with a new ‘tandem’ solar cell design that combines to different technologies to convert almost 30 per cent of sunlight into electricity. The researchers, based at the Helmholtz-Zentrum Berlin research centre and led by professor Steve Albrecht, published the results of their work in the journal Science, saying that they are now confident that conversion efficiencies using the innovative ‘tandem’ solar cell designs above 30 per cent are now within reach. “Tandem solar cells that pair silicon with a metal halide perovskite are a promising option for surpassing the single-cell efficiency limit. We report a monolithic perovskite/silicon tandem with a certified power conversion efficiency of 29.15%,” the research paper says.
