GCL System Integration (GCL-SI), the PV panel unit of GCL Group, unveiled a perovskite solar module at the SNEC trade show in Shanghai in May. The 320 W panel has a power conversion efficiency of 16.02%.
“We are currently planning to raise the efficiency of the panel to over 18%,” a company spokesperson told pv magazine, noting that the module is currently being made on a pilot production line.
The panel measures 2,005 mm x 1,005 mm x 35 mm and weighs 34.5 kg. It uses an encapsulant film based on polyolefin elastomer (POE) and 3.2 mm semi-tempered glass. It can operate with a maximum system voltage of 1,000 V and operating temperatures ranging from -40 C to 85 C.
The company guarantees that the 10-year end power output will be at least 90% of the nominal output power, which decreases to 80% after 25 years.

The company's pursuit of perovskite development is driven by the potential for significantly lower costs compared to silicon products. GCL-SI already operates a 10 MW perovskite production line in Suzhou since 2019, and currently runs a 100 MW line with plans for further scaling to 1 GW.
In the solar perovskite business, the manufacturer operates through its subsidiaries Kunshan GCL Photoelectric Materials Co., Ltd. and Suzhou GCL Nano Technology Co., Ltd.

I’m surprised to see this — I had not heard of any commercially available perovskite modules. Stability has been the big showstopper, so a 25-year power guarantee is really unprecedented.
Shabby yield and heat intolerance, but hey RED and kind of good for measuring by the meter. Semi-temper me up to measure shading effects.
This is interesting but I wanted to know more about other electrical parameters of the developed solar panel, namely Voc and Isc.
