A paper by a scientific team led by the ‘Father of DSC’ Professor Michael Graetzel in the prestigious scientific journal, Nature describes a new deposition process to create the light harvesting pigment for solid-state dye solar cells.
Cells fabricated using this technique and incorporating Dyesol’s key DSC input materials and specially formulated 18NR-T Titania Paste have established a new power-conversion efficiency record of 15% for a solid-state Dye Solar Cell (DSC).
Describing the recent breakthroughs in solid-state Dye Solar Cell technology as truly astonishing, Dyesol Executive Chairman, Richard Caldwell said that the EPFL and Professor Graetzel chose Dyesol as their materials supplier for achieving excellent results and, most importantly, for commercialisation projects and reproducible results. These benefits will be delivered by Dyesol to their major project partners thanks to the company’s ongoing access to this improved technology.
According to Professor Graetzel, their research work on solid-state dye sensitised solar cells is now achieving efficiencies exceeding 15%, and the cells have been externally validated with a world record of 14.1%. At these efficiencies the technology is extremely competitive when compared with conventional solar cells, especially when dye sensitised solar cells do not need perfect sunlight conditions to effectively produce energy.
The research team is particularly encouraged by the program from Dyesol to allow commercial deployment of this game-changing technology in the shortest possible timeframe.
This independently certified efficiency result is now the official world-record for Dye Solar Cell technology performance. The DSC world record efficiency result of 14.1% catapults the energy output of DSC devices to the next level.
One of the many advantages offered by DSC technology over traditional silicon solar panels is the consistent energy output in low-light, dawn, dusk, cloudy, indoor/artificial, and shaded or indirect-light conditions, which means greater cumulative seasonal energy output over the course of a cloudy autumn, dreary winter, and whole year.
The two-step deposition process highlighted in EPFL’s report published in Nature is reproducible, a crucial factor for commercialisation of any technology requiring large scale quantities of product to satisfy a mass-market.
Working closely with EPFL, Dyesol is advancing commercialisation of the mesoscopic technology called Dye Solar Cells by embedding the revolutionary technology onto manufacturing partners' building products, such as steel roofing and glass building façade to meet the growing demand for building integrated photovoltaic products.
