The R&D division of Risen Energy unveiled their new proprietary solar cell design this week. This debut came on the second day of the InterSolar Europe exhibition in Germany. Mr. Wang Hong, the company president, marks Risen HDT cells as another significant milestone in the company’s innovation efforts since the past 30 years.
The Risen HDT cells can reach conversion efficiencies of over 23% with low temperature coefficient and generation temperature. This bifacial solar technology utilizes heterojunction half-cut cells design to generate power from both sides. This can add an extra 30% of energy generation per day. The N-type monocrystalline wafers also ensures better resistance to light induced degradation,
The half-cell architecture further features better shading tolerance, hot spot effect and flexibility in product application. However, the heterojunction cell technology is not new. It has always been restricted by the lack of scalability in its mass production, and a resultant higher retail costs. Risen’s R&D efforts mainly targeted this fundamental issue. The tailoring of Mono PERC, half-cut cells and heterojunction technologies into one cohesive unit was able to overcome these major hindrances. Coupled with the extended warranty periods and the lower retail prices, these new Risen HDT cells can become a reliable option for end-users.
Intersolar Europe is one of the largest solar exhibitions in the world. Held annually in Munich, Germany, the event allows prominent names in the PV industry to showcase their state-of-art innovations and breakthroughs. Risen energy is one of the few top tier-1 solar cell manufacturers that are present here. The exhibition runs from 15-17 May 2019.
As of 2019, Risen is one of Australia’s largest commercial and residential panel brands. Since the start of this year, they are overseeing the construction of two solar farms in the country – 132 MWdc Merredin Solar Farm and 100 MW AC Yarranlea farm. Furthermore, they have numerous active projects in over 3 different continents.
