Ascent Photo voltaic Applied sciences, a developer and producer of thin-film photo voltaic photovoltaic options, says latest check outcomes have proven that the corporate’s proprietary CIGS know-how yields an effectivity score of 17.55%.
In August, the Ascent staff started working to optimize each the manufacturing processes and chemistry of its CIGS know-how. This has resulted in a gradual enhance in effectivity that started with a leap from 10.8% to fifteen.2%; an extra enhance to fifteen.5%; and now this important enhance to 17.55%.
The newest effectivity enhance will be attributed to the addition of rubidium fluoride to the chemistry, mixed with enhancements to Ascent’s manufacturing course of. The enhancements will end in a rise in particular energy within the area atmosphere from 1,900 W/kg to 2,100 W/kg at AM0. This permits the photo voltaic power system to offer extra energy with the identical versatile, resilient and light-weight footprint.
Ascent plans to additional enhance its CIGS know-how effectivity by means of incorporation of Zn(O,S), a skinny movie that’s thought of a promising candidate for a cadmium-free buffer layer, in addition to broader chemistry optimization. Using Zn(O,S) will increase effectivity and particular energy because it expands interactions with mild within the blue spectrum, in addition to helps counter degradation by means of enhancements after mild soak.
