Flexible Solar System

BEST INTEGRATION  -  flexibility, light weight and easy installation

The flexibility of the flexible modules enables them to be integrated onto building components of various shapes and sizes

 

Flexible photovoltaic integrated in buildings with a low cost per square meter.

The specific weight of the flexible BIPV systems is much LOWER than that of crystalline modules, which enables it to be installed on light industrial roofs :

The flexible solar supplier is partnering with international roofing membrane suppliers, to laminate the flexible PV film directly onto various backsheets. This will result in a seamless and cost effective module, to be used as a normal WATERPROOFING membrane.

VHF-coating process
A Very High Frequency Plasma Enhanced Chemical Vapour Deposition Process (VHFPECVD) is used to coat a substrate with nano-scale amorphous silicon layers (0.3 µm). The VHF process has a deposition rate 5 times higher than conventional radio frequency plasma deposition processes, thus resulting in a shorter deposition time. The process temperature is also substantially lower, thus allowing the coating of plastic substrates.

Roll-to-roll manufacturing
The flexibility of the plastic substrate used by Flexcell enables roll-to-roll manufacturing processes, thus allowing high throughput and easy to upscale production capacity.

There are five major steps in our manufacturing process:

  1. Metal coating of a plastic roll
  2. VHF Plasma Enhanced Chemical Vapor Deposition of a-Si layers
  3. Multipass plasma Vapor Deposition of Transparent Conductive Oxide (TCO)
  4. Layer structuring
  5. Module encapsulation with plastic foils
