					</table><p>China-based module manufacturer <a href="https://en.risenenergy.com/" target="_blank" rel="noopener">Risen Energy</a> claimed to have achieved a maximum power of 741.456W with a module efficiency of 23.8% in its Hyper-ion HJT solar module.</p>
<p>The module is backed by Risen&#8217;s 100 μm ultra-thin cell technology and low-temperature process, yielding a carbon footprint value that is lower than 400 kg equivalent CO2/kWc.</p>
<p>The results achieved by Risen were confirmed by security and sustainability solutions partner <a href="https://www.tuvsud.com/en" target="_blank" rel="noopener">TUV SUD</a>.</p>
<p>The company also said its Hyper-ion HJT module has a stable temperature coefficient and increased bifaciality of up to 85% ±10%, capable of maintaining its power output above 90% even after 30 years of use.</p>
<p>Risen Energy&#8217;s Senior Research and Development Director Even Liu said, &#8220;As the latest HJT product, Hyper-ion has the best combination of both improvement and reductions, high power generation, high efficiency and reliability, low degradation, and low-temperature coefficient, low CFP and low levelized cost of energy (LCOE). Risen Energy will continue to innovate and improve our products to promote the era of carbon neutrality.&#8221;</p>
<p>Apart from the use of ultra-thin wafers, other technological innovations like zero busbar technology, hyper-link interconnection, and embedding of encapsulated material helped Risen boost the efficiency of its new HJT series module.</p>
<p>According to Risen, the alloy frame of the HJT hyper-ion module is strong, with the tear-resistant capability of the steel material increased by 20%, which is better than the conventional metal frames.</p>
<p>With rising demand for improved power and efficiency, the global solar sector is focussed on streamlining improved photovoltaic (PV) systems like the heterojunction technology which offers a unique feature of bifaciality.</p>
<p>China has been leading in HJT innovation with continuous research resulting in enhanced power output.</p>
<p>Unlike conventional solar PV technologies like the crystalline silicon or passivated emitter and rear contact, the modules manufactured using HJT technology are tough and damage resistant which offers manufacturers and suppliers relief in terms of transporting the modules from peer to peer.</p>
<p>In January 2023, the Chinese module maker <a href="https://mercomindia.com/chinese-firm-development-710-wp-heterojunction-module/" target="_blank" rel="noopener">announced</a> that its 710 Wp HJT hyper-ion module achieved an efficiency surpassing 22.5% and has an improved stable temperature coefficient and a high bifaciality of up to 85% with a band of ±5%, enabling power output of over 90% even after 30 years of use.</p>
<p>Last December, China-based LONGi Green Energy Technology claimed to have <a href="https://mercomindia.com/longi-says-efficiency-in-heterojunction-silicon-solar-cells/" target="_blank" rel="noopener">achieved</a> a record efficiency of 26.8% for its HJT silicon solar cells on full-size silicon wafers through mass production.</p>
