Production and Testing Capability

The manufacturing base is equipped with advanced production and testing equipment to support controlled processes and consistent module output.

A-Si Thin-Film Device Structure

Thin-film photovoltaic devices are constructed by depositing layers of a-Si:H alloy with different doping agents on a conductive substrate such as TCO-coated glass to form a p-i-n junction, then finishing with a conductive layer as the back contact.

Key Development Directions

• Multi-junction stacks using lower band-gap materials to broaden spectral absorption and improve conversion efficiency
• Light-trapping through TCO and back-reflector surface morphology design to increase absorption and reduce degradation
• Deposition technology such as very high frequency PECVD to improve deposition rate and layer morphology
• Module construction advancements including monolithic integration, encapsulation processing for long-term protection, and large-area deposition to reduce balance-of-module costs

Product Approach

Development work focuses on practical solar energy products designed for everyday applications, with an emphasis on environmental suitability, modern design, usability, and cost-effectiveness.

Amorphous Silicon Benefits

Amorphous silicon (a-Si:H) thin-film photovoltaic technology uses stable, environmentally safe silicon and has been applied across solar battery applications for decades, supporting low-cost power generation.
