CHANGCHUN, China, November. 11, 2019 /PVTIME/ — Amid controversy surrounding Hanergy’s inability to disburse wages to its employees, the Hanergy Chengdu R&D Center released a statement announcing that it has set a new world record for its high-efficiency Silicon Hetero-Junction (SHJ) thin film solar cells. The photoelectric cell conversion efficiency of the full-area (M2, 244.45 cm2) was 25.11%, breaking the previous conversion efficiency record of 24.85% held by itself. The relevant data has been certified by the German Hamelin Solar Energy Research Institute (ISFH).
The record breaking Hanergy SHJ solar cell uses low-cost and easy to acquire ITO transparent conductive film and screen printed electrodes and has very obvious advantages in reducing mass production costs and opening up developing markets. This technological breakthrough is also achieved with low-cost production technology as well as mass production equipment, contrary to many other record-setting technologies that were developed in a laboratory setting. This means that Hanergy’s SHJ technology can be used directly for mass production.
SHJ technology is known as the next generation of highly competitive solar technology. The components produced based on this technology have excellent weather resistance and service life of more than 30 years. They also have high conversion efficiency, stable performance, no light decay, no potential induced attenuation (PID), high power output at high temperature, etc. Making it suitable for use in mobile solar energy, power generating green technology buildings, ground power stations, distributed power stations, vertical installations, solar fishery and agricultural projects.
Xu Xiaohua, Vice President of Hanergy Thin Film Power Group and CEO of Heterojunction Business Unit, said that “the SHJ technology independently developed by Hanergy has been mass-produced in Shuangliu, Sichuan province. The technology has the advantages of high efficiency and low cost, and the core thin film deposition equipment are produced domestically.”
From 2017 to 2019, Hanergy SHJ cell conversion efficiency has steadily increased from 22.85% to 25.11%, all of which have been certified by third parties. However, consecutive efficiency increases year over year has not led to better days at Hanergy. Another world record will not necessarily translate into success for the company unless management can resolve its liquidity issues affecting employee salary payouts promptly.
