Накратко на български

Слънчевите клетки от CIGS се разработват чрез combination от лазерни импулси и специално нанасяне на тънки слоеве материали, за да станат гъвкави и леки. Това помага за намаляване на разходите за производство и ограничаване на парниковите газове чрез възобновяема енергия.

High-performance, ultra-light flexible CIGS Solar Cell

Photovoltaic (PV), a sustainable and renewable source of energy, is the best alternative to suppress the emission of greenhouse gases and limit global warming. The cost of PV systems is dropping continuously, and their energy generation price is not affected by future fuel price increases Among different thin-film PV technologies, the compound semiconductors of the family I-III-VI2, Cu(In,Ga)Se2 (CIGS), exhibit higher power conversion efficiency. CIGS is a polycrystalline direct bandgap material with tunable bandgap between 1.04eV and 1.68eV (depending on gallium concentration), a high absorption coefficient in the visible spectrum, a thin absorber thickness that is 1/100 of that of silicon (Si) solar cells, and excellent radiation hardness. In comparison to Si solar cells (which dominate the present market), they are lighter, significantly cheaper to produce, and can be made flexible. Therefore, I proposed to develop high-efficiency, flexible single-junction CIGS solar cells using the innovative combination of pulsed hybrid reactive magnetron sputtering (PHRMS) and laser pulses. PHRMS is a world-unique, single-step deposition process in which the amount of selenium (Se) in the deposition chamber is precisely controlled, while simultaneously sputtering a Cu-In-Ga thin film. Additionally, with controlled Se pulses, the atomic mobility of anion and cation species was promoted to enhance phase transformation.

Цел на проекта

Photovoltaic (PV), a renewable and a sustainable source of energy, is one of the best alternatives to suppress the emission of greenhouse gases and limit global warming. The cost of PV systems is dropping continuously, and their energy generation price is not affected by future fuel price increases. Among different thin-film PV technologies, CIGS solar cell exhibit the highest power conversion efficiency. It is lighter, significantly cheaper to produce, and can be made flexible to use for portable electronics, mobility applications as well as building integration, which is highly relevant in view of the European Strategic Energy Technology plan. To keep pushing prices down and increase efficiency, a novel concept is needed. Low-temperature growth of high-quality CIGS thin-film opens a new frontier of solar business by fabricating solar cells on ultra-light polymeric substrates. However, the main problems that limit the growth of CIGS thin-films at low substrate temperature are poor electronic properties due to incomplete phase transformation and insufficient alkali metals in the absorber layer due to decreased diffusion. In this project, a pulsed hybrid reactive magnetron sputtering process will be developed to obtain a high-efficiency solar cell at low-growth temperature. It is a new, unique, and single-step fabrication process, which will have a high impact on the industrial production of solar cells. Surface stoichiometry and nucleation of anions/cations species at various deposition conditions will be investigated. Furthermore, the atomic mobility of the anions/cations species will be promoted using laser pulses, which enhances the phase transformation resulting in increased crystal growth. To further boost the performance, heavy alkali metals will be incorporated. High-quality results are expected, since the proposal will combine the expertise of the applicant with the knowledge of the host, and the use of unique state-of-the-art fabrication facilities.
