GLASS-GLASS BLACK BACK CONTACT

BS-108M10BCBB-GG Bifacial glass-glass half-cell module: black Aesthetics meets maximum efficiency

Back Contact (BC) technology is revolutionizing the design of solar modules. Unlike conventional modules, where the current conductors (busbars) are visible on the front, this innovative design relocates all conductor tracks to the back of the cells.

The result: The front side remains completely free of metal conductors, which not only ensures an aesthetic, unobtrusive appearance but also maximizes light yield.

IMPROVED EFFICIENCY

Since the front of the cell is completely free of shading, more active surface area is available. This means greater light absorption and, consequently, higher efficiency.

ANTI SHADING TECHNOLOGIE

Minimizes power loss and keeps solar output stable even in partial shading

IMPROVED TEMPERATURE STABILITY

Thanks to optimized thermal management, BC cells deliver consistent performance even at high temperatures.

BACKWARD CURRENT FLOW

With back-contact technology, the current takes the most direct path, which minimizes resistance losses and maximizes efficiency.

1. CONVENTIONAL SOLAR CELL

In a conventional solar cell, electricity flows through the semiconductor layers. If part of the cell is in the shade, the electrical resistance in that area increases dramatically.

The problem: If the N-type depletion layer lacks structures to route the current around this blockage, the current flow breaks down.
The result: To prevent the cell from overheating (hotspot formation), the bypass diode must kick in. While this protects the hardware, the energy from a large portion of the module is lost and does not contribute to the output.

2. BACK CONTACT SOLAR CELL

Back-contact modules offer a solution through a bipolar layer structure and microchannels.

Active separation: An additional bipolar layer between the N-type and P-type layers creates intelligent detours at the microscopic level.
The advantage: Current can flow more flexibly within the cell. Even if part of the cell is shaded, this structure allows the current flow to be controlled directly at the cell level, rather than shutting down the entire module segment via a bypass diode.

ANTI-SHADING TECHNOLOGY IN DETAIL

Shading caused by chimneys, trees, or similar objects is unavoidable in solar systems. This is where back-contact technology really shines.

The problem with conventional modules

In the event of partial shading, a bypass diode is typically activated to prevent hotspots (overheating). However, this completely interrupts the current flow through the shaded area, resulting in significant power losses.

The Solution

Our back-contact modules utilize anti-shading technology with a bipolar cell design.

Flexible current paths: Instead of shutting down entire cell groups, the module flexibly reroutes the current through alternative paths.
Continuous power output: Unshaded areas continue to operate efficiently. The effects of shading are significantly reduced, without the need to activate bypass diodes.

Always reliable, available and nearly complaint-free. Our modules are the result of more than 20 years of experience in module manufacturing and the renewable energy sector.

HIGHER PERFORMANCE AND EFFICIENCY

Due to the improved durability and lower degradation over time, glass-glass solar modules often achieve higher efficiency and performance compared to conventional modules.

RESILIENCE

The use of toughened glass on both sides reduces the risk of damage from external impacts, e.g. hail or storms, and minimises the risk of fire.

IMPROVED ENVIRONMENTAL COMPATIBILITY

Glass is a recyclable material, which improves the disposal and recycling process of the modules and thus reduces the environmental impact.

ABLE TO WITHSTAND UP TO 620 KG/M²

BAUER’s glass-glass solar modules have a particularly high load-bearing capacity through double glazing.

CERTIFIED TO FIRE CLASS A AND HAIL RESISTANCE CLASS 3

BAUER glass-glass solar modules are extremely weatherproof and fire-resistant because they do not contain an embedding film.

TEMPERED GLASS WITH ANTI-REFLECTIVE TECHNOLOGY

The toughened glass with a thickness of 2 millimetres is dirt-repellent, scratch-resistant, and shock-proof.

The BLACK module from BAUER Solar blends harmoniously into exposed roofs, creating a clean and elegant look. The PURE and PERFORMANCE modules are better suited to transparent and performance-oriented projects, respectively.

The BLACK module from BAUER Solar delivers 460–470 W per module. The PURE module is in the same range, PERFORMANCE slightly above (465–475 W).

The BLACK module offers HW3 hail resistance, fire protection class A, load-bearing capacity up to 620 kg/m², and double-sided glass sealing. BAUER Solar thus guarantees extremely high durability, comparable to PURE and Performance modules.

The BLACK module from BAUER Solar uses Stäubli connectors for minimal contact resistance and maximum safety. The PERFORMANCE module uses MC4-compatible connectors for cost optimization.

The BLACK module from BAUER Solar blends almost invisibly into dark or anthracite-colored roofs. The PURE and PERFORMANCE modules appear less homogeneous in this context.
