Накратко на български

Перовскитните слънчеви клетки се тестват с нов двоен слой от графен и лантан-допиран BaSnO3 за по-добър транспорт на електроните. Това помага за повишаване на ефективността и стабилността им, което ускорява приложението на чистата енергия в практиката.

High efficiency and stability perovskite solar cells based on the functionalized charge transport layers

Efficient and stable solar cell technology has become important means to solving the growing energy and environmental crisis. It has been found to be central to the high-efficiency solar cells that the judicious selection of appropriate charge transport layers. In this work, we fabricated a high-efficiency and stable inverted planar perovskite solar cell, which employed a Lanthanum (La)-doped BaSnO3 (LBSO) / graphene bi-layer as the electron transport layer. Based on “LBSO-template induced perovskite re-nucleation and crystal growth”, the stability and efficiency of our devices have been improved. Through this project, we find a new route to boost the charge carrier collection efficiency and enhance the stability of perovskite. These results are conducive to speeding up the process of the practical application of perovskite solar cells, thereby promoting the development and the application of clean energy.

Цел на проекта

During the past years, photovoltaic technology has shown its greatest potential to be scaled up to meet future energy requirement. Perovskite solar cell (PSC) as a promising next-generation photovoltaic technology has attracted great attention, but its performance is still limited by charge carrier collection efficiency and long-time stability.In this project, the applicant aims to employ novel all-inorganic charge transport layers to fabricate high efficiency and stable inverted planar perovskite solar cells (power conversion efficiency > 23%), based on a functionalized charge transport layer- a Lanthanum(La)-doped BaSnO3(LBSO)/graphene bi-layer. LBSO has a cubic perovskite structure which provides an opportunity to further improve the quality of the interface between the electron transport layer and the perovskite film in conjugation with atmosphere annealing process, which we term “LBSO-template induced perovskite re-nucleation and crystal growth”. A compact conductive graphene layer inserted between the LBSO layer and the metal contact can act as a spacer layer to block the mobile ion and moisture penetration. That will not only improve the device stability (maintain initial efficiency > 90% after 1000 h illumination), but also give a chance to reveal the device degradation mechanism in depth.deeply.
