Nano Technology Low Cost Outperforming Solar Panels The Future of the Global Solar Industry

摘要

Solar Bankers patented new generation of solar modules employs a nano-structured polymer foil on their cover glass, which refracts and concentrates specific wavelengths of light to improve module performance. The optical device refractive abilities allow it to separate absorbable, or “desirable”, wavelengths of solar radiation from efficiency-lowering wavelengths, such as infrared and other short-wave light. The foil then also acts as a lens and concentrates the separated spectra of light onto different areas on the module. Long wavelengths of light, like infrared, are usually dispersed on the solar cell in the form of heat, which significantly reduces cell efficiency. Our nano-structured foil “light-splitting” effect allows efficiency-lowering radiation to be concentrated away from the actual cell, so that cell efficiency remains unaffected by incoming heat. In parallel, the foil is able to concentrate “desirable” wavelengths directly onto the cell. This concentration - regardless of the efficiency of the cell used - increases the amount of absorbable solar radiation received by the cell per unit area by up to 40%. Hence our foil significantly improves cell/module performance with the double-effect of A) protecting cells from efficiency-lowering light while B) increasing the amount of convertible solar energy arriving at the cell per unit area. Our second-generation module can even use the heat energy refracted away from the cell to also produce electricity, further improving module efficiency. This means modules using the foil can reduce the size of the cell - and the amount of silicon! - they employ by up to 90% while producing the same output as before. Given silicon solar cell is the module’s most expensive component, the described effect can reduce module unit production costs to an unprecedented degree. In terms of cost-efficiency, we quote Mr. Ban Ki-Moon, Secretary General of the UN “Low cost solar energy for all”
