At Intersolar Europe, the Chinese producer additionally mentioned that the perovskite-silicon tandem module will value 50% of the crystalline silicon module which prices $0.15 per W, that means $0.075 per W.
Chinese photo voltaic module maker CGL Technology introduced its newest perovskite photo voltaic module expertise on the Intersolar tradeshow in Munich, Germany, this week.
“This module meets IEC take a look at requirements that recommend it’ll degrade to an ordinary much like customary silicon photo voltaic modules,” firm spokesman Martin Wang mentioned. pv journalfamous that the corporate expects this perovskite product to be deployed as a part of a perovskite-silicon tandem photo voltaic module that can start mass manufacturing in late 2025.
Wang additionally revealed that GCL perovskite modules are getting used within the 1 MW perovskite solar energy challenge to be deployed in China’s Three Gorges in late 2023.
The firm says the deployment of its pure perovskite module within the China Three Gorges photo voltaic challenge represents the state-of-field testing stage of the product. The firm hopes to deploy a number of 1 MW tasks earlier than the top of the yr in several geographies with completely different environmental traits, to check the effectivity of the perovskite module.
At the sales space, GCL displayed two perovskite photo voltaic modules: one is a pure perovskite module, and the opposite is a perovskite silicon tandem photo voltaic module. The pure perovskite module has an effectivity of greater than 19%, whereas the effectivity of the tandem module is simply over 26%.
Wang defined that the perovskite photo voltaic panel has handed the TUV Rhineland IEC 61215 and IEC 61739 certification assessments, which might recommend that the photo voltaic modules will degrade like an ordinary silicon photo voltaic panel. Wang defined that GCL is shifting slowly out there with that assertion as a result of the assessments are designed to break silicon merchandise, and never perovskite merchandise.
GCL gives pv journal with IEC certification doc. Additional documentation is requested to higher perceive the outcomes of the impairment.
The modules from the 100 MW take a look at line which were in place since 2021. Most of the modules from this take a look at line, which amounted to 10 to fifteen MW in 2023, have been recycled, whereas the modules have progressed to models that they really feel they deserve. in deployment.
Wang mentioned that GCL believes that the degradation of their perovskite silicon tandem module is healthier than that of normal silicon modules. Starting on the finish of subsequent yr, GCL will begin deploying its perovskite silicon tandem photo voltaic module.
A key product specification that differentiates it from many others available on the market is that the tandem side of the product is on the module degree – not the cell degree. What the producer means is that “95% of the exhausting work” has been achieved in making the perovskite module.
Wang additionally defined that combining two photo voltaic panels is a a lot easier course of than making a tandem photo voltaic cell, and that with hand-made perovskite silicon tandem modules, the models work 95% of the time. , and that when the manufacturing line is in place. this worth reaches virtually 100%.
Wang mentioned that on a cost-per-watt foundation – not anticipated market worth – the corporate expects the perovskite silicon tandem module to value 50% of a crystalline silicon module that prices $0.15 per W, that means $0.075 per W. He mentioned that the 50% worth used within the advertising and marketing of perovskite silicon modules is made when polysilicon is costlier, and thus modules are costlier.
When requested this pv journal about future effectivity positive aspects, Wang mentioned GCL – on this case – is a perovskite firm first. “We want to understand the total potential of perovskites, and we have to adapt silicon to perovskites – as a substitute of the opposite approach round,” he mentioned.
Next yr, they anticipate the tandem module to interrupt 27% effectivity – with greater than a 30% “assure”. Currently, within the tandem construction, it’s the perovskite module that contributes many of the effectivity, as a result of it generates 19% – whereas the silicon runs solely 7% effectivity.
The present silicon base module used is a TOPCon unit, nonetheless, GCL believes that the heterojunction is the most effective long-term answer because of the increased voltage of the product.
