In the wave of building-integrated photovoltaics (BIPV), no single technology can dominate all application scenarios.
Based on CdTe thin-film cells and HJT heterojunction cells, we have developed a one-stop BIPV solution that balances aesthetics and efficiency, and integrates safety with economic benefits. The two technologies are not mutually exclusive alternatives, but an ideal combination to cover all architectural scenarios.
I. Shared Genes: The "Photovoltaic Skin" Naturally Tailored for Buildings
Both technologies feature the three core attributes essential for BIPV:
1. Excellent low-light power generation performance: It can steadily generate electricity in early morning, dusk and rainy & cloudy days.
2. Superior shading resistance: Building facades are inevitably partially sheltered by external air conditioners, decorative lines and other structures. Both cells can keep power loss to a minimum.
3. Insensitive to installation angles: They maintain high power generation efficiency on vertical walls, inclined roofs and even curved domes, breaking the reliance of traditional photovoltaics on the optimal installation angle.
II. Complementary Strengths: Match the Right Cell to the Right Application
CdTe —— The Aesthetic Glass & Safety Guardian for Buildings
When buildings demand transparency, visual appeal and ultimate safety, CdTe stands as an irreplaceable solution.
Aesthetics & Transparency
It supports translucent design with customizable colors and light transmittance, enabling photovoltaic modules to integrate seamlessly into building curtain walls, instead of looking like an afterthought patch.
Ultra-high Safety
There have been no publicly reported fire incidents involving CdTe cells to date. It delivers outstanding safety advantages for crowded places such as commercial complexes, schools and hospitals.
Applicable Scenarios
Daylighting roofs, viewing curtain walls, historical building renovation, high-end commercial facades and more.
HJT —— High-yield "Efficiency Engine" and "Cost-effective Solution"
For buildings with large, unobstructed roofs or walls where the top priorities are quick investment payback and maximum power generation revenue, HJT is the optimal choice.
High conversion efficiency and cost advantages: It delivers higher power output per unit area, bringing faster and better economic returns.
Excellent 4-split compatibility: The low-current design effectively reduces hot spot risks, enhances shading resistance and system safety. Meanwhile, it lowers internal power consumption and improves production yield, offering remarkable cost benefits.
Applicable scenarios: Opaque facades (curtain walls, connecting corridors, noise barriers), industrial and commercial factory rooftops, parking lot canopies, sloped roofs of new residential buildings, etc.
III. Complementary Collaboration: One Building, Two Technologies, Perfect Division of Labor
A typical commercial park can adopt the following configuration:
South-facing facades and daylighting atriums → Adopt CdTe modules to maintain transparent aesthetics, provide basic power generation, and present an eco-friendly image to the public.
Large-area roofs and carports → Adopt HJT to maximize installed capacity and annual power generation, and rapidly generate electricity revenue.
