At the key node of green buildings moving towards capacity-based development, a new type of self-cleaning daylighting tile that combines high-efficiency light guide and photovoltaic power generation functions has triggered revolutionary changes in the industry.This innovative product organically combines passive lighting with active production capacity, not only redefines the energy role of the building enclosure system, but also achieves long-term stable performance output through an intelligent self-cleaning mechanism.

Traditional photovoltaic components often face the contradiction between light transmittance and power generation efficiency.The new type of lighting tile adopts a precise optical partition design, and innovatively integrates micro-photovoltaic chips at the edge of the tile while maintaining an overall light transmittance of 72%.Through a special optical guidance structure, the direct strong light is automatically guided to the photovoltaic area to convert electrical energy, while the soft diffuse light continues to provide natural lighting for the interior, achieving a single-day power generation efficiency of up to 0.8 kWh per square meter, while ensuring the comfort of the indoor light environment.

The breakthrough self-cleaning technology is another highlight of this product.The nano-photocatalytic coating covered by its surface can continuously decompose organic pollutants under light, and with a special hydrophobic micro-texture structure, rainwater can form a water film that rolls off quickly on the surface, keeping the translucent surface clean all year round.The measured data show that the technology has reduced the annual attenuation rate of lighting efficiency from the industry average of 3.2% to less than 0.8%, greatly reducing maintenance costs and water consumption.

With the global promotion of the concept of "building as a power plant", building materials with both production capacity and lighting functions are becoming the focus of the market.This innovative product, which deeply integrates optical engineering, energy technology and materials science, has been successfully applied in a number of near-zero energy consumption demonstration projects in China.It not only represents the transformation of building materials from energy consumption units to production capacity units, but also through continuous and stable clean energy output and near-zero maintenance operating characteristics, it provides a quantifiable technical path for the sustainable development of the whole life cycle of the building, marking that the building skin has officially entered a new era of active production capacity and intelligent self-sustainment.
