From BIPV (Building Integrated Photovoltaic) to BIPVES (Building Integrated Photovoltaic and Energy Storage)
Abstract
[Introduction] With the development of photovoltaics, energy storage, new building materials and prefabricated construction industry, Building Integrated Photovoltaic (BIPV) technology which features the integrated design and manufacturing of photovoltaic modules with components such as roofs, walls and sunshades is evolving as Building Integrated Photovoltaic and Energy Storage (BIPVES) technology. [Method] The article proposed the world's first rechargeable cement-based battery, promoting the integration of building walls with photovoltaic power generation and storage and discharging devices. Cross-disciplinary innovation was applied to equipment and materials, where high-definition, high transmittance patterned designs were printed on glass surfaces to manufacture high-efficiency photovoltaic building materials. Prefabricated energy storage walls were developed and integrated with various steel-structure prefabricated building systems to achieve customized production and prefabricated construction, leading to a transformative trend of integrating building components with photovoltaics and energy storage. [Result] Cement-based batteries allow building walls to have multiple functions, including photovoltaic power generation, energy storage and power supply; The new generation of photovoltaic building materials helps save costs on building facade decoration materials and reduce building carbon emissions; The integration of photovoltaics, energy storage and renewable energy technologies in buildings can achieve maximum benefits. [Conclusion] The new photovoltaic building materials and new energy storage technologies such as cement-based batteries show promising prospects. Combining and integrating rechargeable battery components, photovoltaic exterior panels, prefabricated building walls and embedded parts for widespread application is feasible.
