Накратко на български

Слънчевите клетки с тънък абсорбиращ слой и структури от паралелни наноканали се анализират, за да се оптимизират геометрията и материалите им. Това помага за повишаване на ефективността и намаляване на разходите при производството на възобновяема енергия без вредни емисии.

Organic-Inorganic Hybrid Heterojunctions in Extremely Thin Absorber Solar Cells Based on Arrays of Parallel Cylindrical Nanochannels

• What is the problem/issue being addressed? Innovation and cutting-edge research in energy are necessary to reach sustainability and competitiveness in the energy sector and to revert the effects of the climate change that we are facing. In December 2019, it was presented the “European Green Deal” with the objective to reach a climate-neutral European continent by 2050, and renewable energies will play a crucial role to reach these objectives. To meet this projection, renewable energy systems must increase their efficiencies, reduce costs, and be integrated into applications to optimize their contribution to the electrical supply. Therefore, renewable energies and, in particular, solar energy conversion systems present a field of technology and research of utmost importance for EU’s energy and climate change policies. • Why is it important for society? We are facing a climate and environmental crisis that eventually would have a direct effect on society. The actions taken now will decide the direction of the change that we are facing. Research on new materials and technologies that offers avenues to benefit from energy resources with CO2-free emissions is contributing to an energetic and economical model that is sustainable which will have a positive reflection into the society. • What are the overall objectives? The HYBRICYL project is dedicated to the systematic study and understanding of the factors that limit the efficiency of PV devices from an innovative and scalable approach based on low-cost and low-toxicity materials structured in coaxial structures. This work intends to provide the PV community with new tools to optimize geometrical parameters for more cost-efficient solar energy conversion devices.

Цел на проекта

HYBRICYL project presents novel preparative methods developed towards the fabrication of organic-inorganic heterojunctions in coaxial geometry using arrays of parallel cylindrical nanochannels. The aim of this project is to provide new experimental insight into the function of photovoltaic (PV) systems and optimize the geometrical parameters to improve their efficiency. The goal structures will be achieved based on three different elements: a) nanoporous anodic aluminum oxide (AAO) films, b) atomic layer deposition (ALD) of inorganic semiconductors, and c) the use of organic semiconductors as hole transporter materials and bulk heterojunctions. Nanoporous AAO will be used as template due to the great geometrical flexibility achievable, diameter = 20 - 400 nm; interpore distance = 50- 500 nm; length = 0.1 - 10 um, in self-ordered domains of nanopores. The ALD will be used to coat homogeneously the nanochannels of the AAO with electron conductor materials (TiO2) and light absorber (Sb2S3). The thickness of these layers will be ranging from 5 to 50 nm. Finally, organic hole transporter materials and bulk heterojunction will be infiltrated into the nanochannels in contact with the light absorber to form coaxial organic-inorganic heterojunctions in arrays hexagonally ordered nanochannels. The optical and electrical properties of these PV structures will be studied for a better understanding of the physical process involved. In particular, a series of organic semiconductors will be systematically investigated. This will allow us to optimize the geometrical parameters in function of the charge carriers transport distances (hole mobility) and quantity of light absorbed (absorption coefficient). We will identify the limiting factors of the solar cell efficiency. We will be able to fabricate devices with tailor made geometries to improve the charge generation and collection, and reduce the recombination processes at the interfaces, thereby improving their efficiencies.
