SPIC Solar, an early adopter of IBC technology and a subsidiary of State Power Investment Corporation (SPIC), showcased its latest low-silver-content Zebra IBC module, along with an all-black BIPV model during Intersolar Europe 2025.
Zebra IBC Module
The back contact (BC) module on display consists of 120 half-cut Zebra IBC cells. The rear sides of these cells are metallized with Copprint’s copper inks, which significantly reduces the silver content in the cell. Copprint, an Israel-based company, focuses on providing conductive copper paste for PV metallization. These cells have both copper fingers and copper busbars. The cell-to-cell interconnection has been achieved through a tin-lead (Sn-Pb) solder ribbon, further minimizing silver content in the module. According to the company, the displayed module contains less than 5 mg/W of silver content, making the product both cost-effective and environmentally friendly.
BIPV Module
Alongside the low-silver-content Zebra IBC module, the company’s stall also featured an all-black dual-glass BIPV module. This module, equipped with 120 M6 size TBC half-cells, boasts a power output and an efficiency of up to 410 W and 22.5%, respectively. The full-black anti-glare appearance prevents light pollution, making the product suitable for BIPV applications.
The anti-glare performance of a BIPV module is a critical aspect, not only for visual comfort and aesthetic quality of the building facade, but also for the safety and environmental harmony of surrounding areas. To give some context, high-reflectivity modules can cause intense glare under low solar angles, potentially disturbing pedestrians and occupants of nearby buildings, and even leading to light pollution. In contrast, all-black modules utilize low-reflectance surface treatments that reduce visible light reflectivity to below 3%, effectively minimizing glare. This makes them more compliant with green building codes that limit the reflectivity of construction materials. The anti-glare design enhances the visual uniformity and subdued elegance of the building exterior, fulfilling both aesthetic and functional demands of high-end projects where PV modules also serve as architectural elements.
SPIC claims that this module exhibits good low-light performance in overcast conditions, dusk, or dawn.
