Q1. With the shift to N-type technologies like TOPCon and HJT, how are Alishan’s advanced encapsulants—such as EPE-NT and EPE-DC—addressing critical challenges like moisture ingress and UV-induced degradation?
The industry is shifting from P-type to N-type cells like TOPCon and HJT because of their higher efficiency and lower degradation. But with these benefits come new challenges. N-type cells are more sensitive to UV stress and moisture and they require encapsulants that offer stronger barriers and stability.
Alishan EPE-NT was developed specifically for this need. It blends the processability of EVA with the moisture barrier and electrical properties of POE, ensuring higher reliability for bifacial and glass-glass modules. With N-type adoption accelerating, materials built for the future are no longer optional, they are essential.
On the other hand, UV Induced Degradation (UVID) is a silent threat to advanced cell technologies. In TOPCon and HJT, ultra-thin passivation layers like silicon oxide and polysilicon can degrade under UV exposure. This creates defects at the interface, reducing power output over time.
Encapsulants play a critical role in protecting against UVID. Alishan EPE-DC uses UV down-conversion technology to transform harmful UV into visible light while shielding sensitive layers. This not only protects cells but also boosts module performance.
Q2. How are Alishan’s new encapsulants built to withstand India’s harsh climates, and how do they support your expansion and Atmanirbhar Bharat goals?
For solar modules to last in India, they need materials that can handle every kind of weather, from the humidity of coastal regions to the extreme heat of deserts.
At Alishan Green Energy, we are expanding our encapsulant capacity to 6.6 GW by year end with a vision to reach 10 GW backed by our 3 GW backsheet capacity. This year we have launched three new products, each developed to critically tackle the ongoing issues of UVID and moisture ingress in latest technologies. Alishan low acid EVA, Alishan EPE-NT and Alishan EPE-DC are new age encapsulants which we will be showcasing at REI along with their special features and unique testing that we have adopted.
Every product we launch is developed, tested, and manufactured in India, aligned with the Atmanirbhar Bharat vision. Our mission is to provide quality products and serve the solar industry in India.
Q3. Is Alishan planning to expand into other verticals beyond encapsulants and backsheets?
Yes, we are mulling over the possibilities to expand in other verticals which suit our expertise and demand in India. We will announce the progress soon.
Q4. Can you share more about your 10 GW expansion plan and the potential joint ventures with leading module manufacturers in India?
As we mentioned, 10 GW is our independent expansion plan and by this year end we will be at 6.6 GW. On the other hand, we are happy that we are being considered as partners by many Tier 1 Manufacturers to support their vertical integration by joint venture and strategic partnerships. We are in talks with two major module manufacturers of India and we are certain that soon we will be able to share more information.
