Perovskite solar cells break efficiency record at 29.9%

24 Nov 2023 CW Team

Perovskite solar cells have long held promise due to their low cost, high efficiency, and ease of fabrication. However, their widespread adoption has been hampered by electrical and optical losses that limit their performance. To address this challenge, the research team developed a new method for fabricating perovskite solar cells that overcomes these limitations.

The key innovation ??????????? en el apilamiento mec?nico de la celda perovskita superior y la celda CIGS inferior, creando una estructura ?pticamente acoplada pero el?ctricamente independiente. Esta configuraci?n elimina la interacci?n entre la capa perovskita y las capas reactivas de la celda inferior, lo que permite una mayor flexibilidad de dise?o.

Adem?s, el equipo introdujo nuevas t?cnicas el?ctricas y ?pticas, utilizando "yoduro de dimetilamonio" y ajustando el espectro de interferencia ?ptica. Estas t?cnicas permitieron alcanzar una eficiencia r?cord de 20.2% para una celda perovskita semitransparente y una transmitancia cercana al infrarrojo promedio de 81.5%. Al combinarla con una celda inferior de CIS, la eficiencia en t?ndem alcanz? un notable 29.9%.

La separaci?n de las dos celdas durante el proceso de fabricaci?n simplifica la producci?n, reduce los costos de capital y acelera la entrada al mercado, facilitando as? la comercializaci?n. Un estudio de viabilidad comercial demostr? que el t?ndem de pel?cula fina de perovskita/CIGS 4T puede alcanzar un escenario competitivo en t?rminos de costos a pesar de su mayor costo de fabricaci?n debido a su alto potencial de rendimiento energ?tico.

Este avance tecnol?gico abre nuevas oportunidades para diversificar las celdas en t?ndem basadas en pel?culas delgadas de perovskita o CIS, allanando el camino para una nueva generaci?n de paneles solares m?s eficientes, econ?micos y vers?tiles.

A team of researchers from the National University of Singapore, Empa Materials Science and Technology, and the Helmholtz Institute Erlangen-N?rnberg for Renewable Energy has made a significant breakthrough in solar cell technology by achieving a record efficiency of 29.9% for a semi-transparent perovskite cell. This achievement paves the way for wider commercialization of perovskite solar cells, which have the potential to revolutionize the solar industry.

Railways To Operate Over 300 Special Trains For Rath Yatra

Union Railway Minister Ashwini Vaishnaw announced that Indian Railways (IR) will operate more than 300 special trains for the annual Jagannath Rath Yatra in Odisha and over 100 special trains during the Onam festival in Keralam. He flagged off the Nanded–Mumbai and Tanakpur–Nanded Express trains and inaugurated the extension of the Tanakpur–Pilibhit service up to Shahjahanpur via video conference from Rail Sadan in Bhubaneswar. He noted that the summer season, which concluded on 30 June, had seen a record 15,000 special trains. Vaishnaw stated that the newly launched services are intende..

Vande Bharat Express To Start From Tripura Soon

Tripura Chief Minister Manik Saha said the Vande Bharat Express will commence operations from Tripura in the coming days after he flagged off the Agartala–Karimganj MEMU service at Agartala Railway Station. He recalled the rail history of the state, noting that a metre-gauge service first arrived in 1964 and that broad gauge reached Agartala in 2008 following national projects and later upgrades under the Act East policy. The event was described as a milestone for regional connectivity and the MEMU was presented as the first electric passenger train to originate from Tripura.\n\nSaha said he..

MEMU Suspension Disrupts Commuters Between Vadodara And Dahod

The Vadodara–Dahod Mainline Electric Multiple Unit (MEMU) service has been temporarily suspended for 26 days after its rake was diverted to Odisha to manage the surge in passenger traffic during the annual Rath Yatra in Puri. Indian Railways redeployed several MEMU rakes from different zones to meet the additional travel demand for the festival scheduled from the seventh of July to the second of August. As a result, train numbers 69233 and 69234 operating between Vadodara and Dahod will remain cancelled for the duration. Railway authorities advised passengers to use alternative train service..
