A group of scientists at the National University of Singapore (NUS) have achieved a\u00a0groundbreaking\u00a0new record in the power conversation efficiency of solar cell technology.\u00a0<\/span>\u00a0<\/span><\/h2>\n

The team\u2019s results were published in the journal\u00a0<\/span>Nature Energy<\/span><\/i>\u00a0on 20 January 2022\u00a0and the\u00a0research was\u00a0carried out\u00a0as part of a\u00a0partnership\u00a0with\u00a0researchers\u00a0from the University of Hong Kong and\u00a0the\u00a0Southern\u00a0University of Science and Technology.<\/span>\u00a0<\/span><\/p>\n

Solar cell technology for a green future<\/span>\u00a0<\/span><\/h3>\n

\u201cTechnologies for clean and renewable energy are extremely important for carbon reduction. Solar cells that directly convert solar energy into electricity are among the most promising clean energy technologies. High power conversion efficiency of solar cells is critical for generating more electrical power using a limited area and this, in turn, reduces the total cost of generating solar energy,\u201d\u00a0said\u00a0lead researcher Presidential Young Professor\u00a0Hou\u00a0Yi, who is from the NUS Department of Chemical and Biomolecular Engineering.<\/span>\u00a0<\/span><\/p>\n

Enhancing power conversion rates<\/span>\u00a0<\/span><\/h3>\n

\u201cThe main motivation of this study is to improve the power conversion efficiency of perovskite<\/a>\/organic tandem solar cells. In our latest work, we have demonstrated a power conversion efficiency of 23.6% – this is the best performance for this type of solar cells to date,\u201d\u00a0explained\u00a0Dr Chen Wei, Research Fellow at the NUS Department of Chemical and Biomolecular Engineering and the first author of this work.<\/span>\u00a0<\/span><\/p>\n

This\u00a0accomplishment\u00a0represents a massive\u00a0jump forward\u00a0from the\u00a0present\u00a0power conversion rate of\u00a0around\u00a020%, which has been\u00a0recorded\u00a0by\u00a0previous\u00a0studies on perovskite\/organic tandem solar cells.<\/span>\u00a0<\/span><\/p>\n

The new research is close to\u00a0the power conversion rate of 26.7% of silicon solar cells, which is the\u00a0leading\u00a0solar\u00a0cell\u00a0technology in the current solar photovoltaic (PV) market.<\/span>\u00a0<\/span><\/p>\n

Trends in solar technology<\/span>\u00a0<\/span><\/h3>\n

Solar cell technology has\u00a0attained\u00a0remarkable\u00a0development\u00a0in recent years as\u00a0it presents a promising\u00a0sustainable energy source.\u00a0The\u00a0consistency,\u00a0productivity,\u00a0resilience, and\u00a0cost\u00a0of solar cells\u00a0has\u00a0a\u00a0major effect\u00a0on the commercial potential and large-scale implementation of solar energy projects around the world.<\/span>\u00a0<\/span><\/p>\n

Currently, the standard\u00a0cells\u00a0being used in solar\u00a0power plants are\u00a0centred\u00a0on a single-junction architecture. The practical power conversion efficiency of single-junction solar cells is\u00a0restricted\u00a0to\u00a0approximately\u00a027% in industrial production.\u00a0<\/span>\u00a0<\/span><\/p>\n

In order to\u00a0push the\u00a0limits\u00a0of solar energy\u00a0manufacturing,\u00a0innovative solutions are required\u00a0for solar cells to perform better in power conversion.<\/span>\u00a0<\/span><\/p>\n

To\u00a0develop\u00a0the power conversion efficiency of solar cells to\u00a0more than\u00a030%, stacks of two or more absorber layers (multi-junction cells) are\u00a0necessary. Tandem solar cells, which are\u00a0comprised of\u00a0two\u00a0varieties\u00a0of photovoltaic materials, is\u00a0a\u00a0fast-developing\u00a0area of research.<\/span>\u00a0<\/span><\/p>\n

The NUS team\u2019s\u00a0novel\u00a0discovery\u00a0paves the way\u00a0to thin-film tandem solar cells that are light and bendable, which\u00a0may\u00a0have\u00a0a range of\u00a0applications, including the potential for\u00a0solar-powered blinds, vehicles,\u00a0boats\u00a0and other mobile devices.<\/span>\u00a0<\/span><\/p>\n

Revolution\u00a0in efficiency<\/span>\u00a0<\/span><\/h3>\n

A tandem solar cell consists of two or more subcells electrically attached through interconnecting layers (ICLs). The ICL performs a significant role in establishing the performance and duplicability of a device. An efficient ICL must be chemically inert, electrically conductive, and optically transparent.<\/span>\u00a0<\/span><\/p>\n

While\u00a0perovskite\/organic tandem solar cells are\u00a0promising\u00a0for next-generation thin-film photovoltaics, their\u00a0productivity\u00a0falls short of other\u00a0types of tandem solar cells.\u00a0In order to\u00a0overcome\u00a0this technological challenge,\u00a0Asstistant\u00a0Professor\u00a0Hou\u00a0and his team\u00a0created\u00a0an efficient\u00a0ICL that\u00a0decreases\u00a0voltage, optical and electrical losses within the tandem solar cell.\u00a0<\/span>\u00a0<\/span><\/p>\n

This\u00a0advancement\u00a0substantially\u00a0enhances\u00a0the\u00a0productivity\u00a0of the\u00a0perovskite\/organic tandem solar cells, achieving a power conversion rate of 23.6%.<\/span>\u00a0<\/span><\/p>\n

\u201cOur study shows the great potential of perovskite-based tandem solar cells for future commercial application of photovoltaic technology. Building on our new discovery, we hope to further improve the performance of our tandem solar cells and scale up this technology,\u201d\u00a0concluded\u00a0Hou.<\/span>\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
