Natcore太陽能公司稱,該公司一項超高效太陽能電池項目已獲成功。
該公司說,賴斯大學(xué)研已成功地將一個涂層硅量子點封裝入二氧化硅。該方案由教授Andrew Barron帶頭,是一項全硅、高效太陽能電池串聯(lián)發(fā)展的重要里程碑。 在二氧化硅中封裝個納米晶體硅個體 - 硅量子點是一項突破性的技術(shù)。
現(xiàn)在,Natcore公司在全球范圍內(nèi)享有該技術(shù)專利權(quán)。公司將創(chuàng)建三維陣列,吸收比普通晶體硅波長更短的多層次光硅量子點。
Natcore估計,堆積陣列將將在成本更低的情況下提高每瓦額外效率,太陽能電池串聯(lián)效率可達(dá)30%。
據(jù)Natcore,串聯(lián)太陽能電池,目前旨在太空中使用,但地球上申請使用其上層需用“外星”半導(dǎo)體材料。但是,LPD高科技免除了昂貴技術(shù)的需求。
A project to create a super efficient solar cell has proved successful, according to Natcore Solar.
The firm said that a research programme at Rice University has successfully encapsulated silicon quantum dots with a uniform coating of silicon dioxide.
The programme, conducted by Professor Andrew Barron, is a major milestone in the development of an all silicon, highly efficient tandem solar cell, the company claimed. Encapsulising individual silicon nanocrystals - quantum dots - in silicon dioxide is a breakthrough technology.
Natcore has an exclusive worldwide licence for that technology. Natcore will now create multiple layers of silicon quantum dots in 3D arrays that will absorb shorter wavelength light than in ordinary bulk silicon.
Natcore estimates that the stacked arrays will increase the efficiency at a lower cost per extra watt, with efficiency of over 30 percent for tandem solar cells being likely.
According to Natcore, tandem solar cells are currently used in space applications but earth based appps need to use "exotic" semiconducting materials for the upper layers. But LPD tech eliminates the need for the expensive technology.
