Driven by renewable energy policies, solar demand in Korea has surged; however, it is now hindered by land scarcity and restrictions on transmission grid expansion.
Accordingly, KEPCO has developed window-type solar cells using single-junction perovskite—a technology with high technical difficulty but strong potential for commercialization, specifically targeting the BIPV (Building Integrated Photovoltaics) market.
We are developing semi-transparent perovskite modules with a size of 15x15cm2, 30% transmittance, and an average efficiency of 11%.
For the goal of commercialization, we are fabricating window-type panels incorporating an array of 54 modules, assembling the BIPV unit by wiring interconnections and attaching the window frame.
The fabricated photovoltaic glass window was installed on an urban building, and the generated electricity was successfully used to operate household appliances.
However, to enter the BIPV market and compete with silicon solar cells, the key challenges we must address are the long-term durability and product reliability of perovskite modules and panels.
In the future, we aim to build a reliable track record with manufacturers through on-site demonstration projects to address these issues.
This work was supported by the Korea Electric Power Corporation (KEPCO) under the project [Development of 200W-class Perovskite Solar Cell Windows]. The authors would like to express their gratitude to the collaborating institutions for their technical support and contribution to the demonstration and reliability testing of the photovoltaic glass window.
nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
