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.
