Solar testing group warns of degradation risk for TOPCon
The Renewable Energy Test Center (RETC) raised the issue of ultraviolet-induced degradation of the trending technology in its PV Module Index 2022.
Chinese module prices to fall by 15% from Q4 2022 to Q4 2023, says CEA
Solar module prices will be pressured by rising industrial capacity this year, with capacities doubling in the ingot/wafer stages and potentially quadrupling for polysilicon by 2027, according to the latest PV pricing report from Clean Energy Associates (CEA).
Case study demonstrates 5% energy yield boost for n-type TOPCon modules
Data collected from a 30 MW PV project in China’s Tianjin Province demonstrates that n-type tunnel oxide passivated contact (TOPCon) modules achieve a little more than 5% more energy yield than p-type PERC. Analysis by JinkoSolar, which supplied its TOPCon modules to the project, credits the n-type modules’ increased performance to a better temperature coefficient in the project’s hot climate, higher bifaciality and lower degradation.
TOPCon shingle solar cell achieves 22.0% efficiency via thermal laser separation
Scientists from Germany’s Fraunhofer ISE and US panel maker Solaria have applied thermal laser separation and post-metallization passivated edge technology to tunnel oxide passivated contact (TOPCon) cell production. They have developed shingle PV devices that are more efficient than cells built with conventional laser scribing and mechanical cleaving methods.
SEG Solar releases 580 W TOPCon solar modules with 22.45% efficiency
California-based SEG Solar says its new panels have a temperature coefficient of -0.30% per degree Celsius. They come with a 30-year power output guarantee for 87.4% of the initial yield.
Axitec expands solar panel capacity to 2 GW
Module manufacturer Axitec is ramping up its production capacity in China, India and Vietnam to meet growing demand for PV modules in Germany, Austria and Switzerland.
Emmvee starts building new solar cell and module line
Karnataka-based Emmvee Group is constructing a 1.5 GW cell line with integrated 1.75 GW module capacity in Karnataka. The new facility will expand its overall module capacity to 3 GW.
Websol to commence first phase of 1.8 GW mono PERC cell line in April
West Bengal-headquartered Websol Energy Systems is setting up 1.8 GW of mono PERC cell manufacturing capacity in two phases. The first phase comprising installation of 600 MW will commence in April.
Emmvee gets Fraunhofer ISE on board for solar cell line
India’s Emmvee Group has appointed Germany’s Fraunhofer Institute for Solar Energy as the technology partner for its upcoming 1.5 GW PV cell manufacturing facility.
JinkoSolar unveils new TOPCon solar products with record efficiency ratings
Chinese module maker JinkoSolar has released three new TOPCon solar panel variants, ranging in power from 445 W to 635 W. The most efficient modules have a rating of 23.23%. The bifacial factor is up to 85% across the three panel types, with a temperature coefficient of -0.29% C.
