Waaree Unveils Highly Efficient N-type TOPCon and HJT PV Modules

Waaree Energies Limited (WEL) is India’s largest solar PV Company with 5GW of operational module manufacturing capacity. WEL strives to provide high-quality and cost-effective energy solutions in the renewable sector. Advanced technology adoption, design, strong process control, flexibility, recycling inception, accelerated performance and reliability testing are the important pillars which has helped Waaree to emerge as a technology leader, and a continuous performer (being rated as Tier 1 module manufacturer by Bloomberg NEF since past more than 20 quarters) and the largest PV module manufacturer in India. Waaree is aiming to be self-reliant by the year 2024-25.

WEL is happy to announce that they are launching highly efficient and most advanced TOPCon N-type PV modules in M10 and M12 configurations as well as HJT modules in M10 and M12 configurations in both Bifacial glass to glass and mono-facial variants. WEL will be the first Indian company to launch TOPCon N-type and HJT PV modules and the modules will be showcased in SPI (Solar Power International) 2022 Anaheim, USA, and REI (Renewable Energy India Expo) 28th-30th Sept 2022, Greater Noida, India.

Waaree’s R&D team and quality control team is constantly working for years to provide highly efficient, superior quality, reliable, and cost-competitive products and services in the green energy domain.

TOPCon (Tunnel Oxide Passivated Contact) which is considered to be the next generation of solar cell technology consists of the additional tunnel oxide layer and doped poly-Si layer for better passivation and improved performance. TOPCon N-type solar cell-based modules have certain advantages over conventional P-type Mono PERC modules listed as under:

1. High efficiency and high wattage modules with better performance and reliability.
2. Lower temperature coefficient -0.3 to -0.31 %/°C as compared to Mono PERC modules -0.34 to -0.35 %/°C thereby lower temperature losses and higher energy yield.
3. Excellent anti-PID performance.
4. The lower first-year degradation rate is around 1% as compared to 2% in p-type Mono PERC modules.
5. Zero LID and lower LeTID losses due to phosphorous doping (no boron-oxygen defects).
6. Lower year-on-year (YOY) degradation rate of -0.4% as compared to -0.55% for Mono PERC modules.

The HJT (Hetero Junction with Intrinsic thin layer) PV modules are made from HJT cells which consist of the n-type wafer that utilizes both amorphous & crystalline silicon technology in their cell structure. The n-type monocrystalline silicon layer in the cell has better light absorption whereas the amorphous layers have superior passivation characteristics which enable high electron collection. Key Features of HJT PV modules are listed as under:

1. No effect of PID, LID & LeTID.
2. Best in class power output for given module size.
3. Bifaciality factor of the module above > 90% realized.
4. Lower power temperature coefficient (-0.26 %/°C) of the module.
5. MBB module – Highly resistant to micro cracks.
6. Higher reliability and lower degradation rates.
