The solar industry has danced between monocrystalline and polycrystalline, each with its own pros and cons. Enter technological innovations, paving the way for more efficient, cost-effective solar modules. But what about the outdoor performance after a year and a half? Let’s break it down.
The Evolution of Solar Tech:
From diamond wire cutting to double-sided wonders, solar tech has witnessed remarkable innovations. But as we push the boundaries of component size, the focus now shifts to enhancing battery efficiency for further cost reduction.
Efficiency Breakdown:
P-type PERC modules have been the stalwarts, reaching around 23% efficiency, but progress has its limits. The real star, however, is N-type TOPCon, boasting a sky-high technical efficiency of 28.7%, with characteristics like low attenuation and high weak light response. It’s the go-to for many industries.
Comparative Power Play:
Enter the big players – TOPCon, HJT, and IBC. SPIC’s 18-month study reveals the following:
TOPCon Triumph: Among the trio, TOPCon steals the spotlight with the highest power generation capacity. Its bifacial ratio and attenuation rate outshine HJT and IBC components.
N-Type Dominance: N-TOPCon, N-HJT, and N-IBC show increasing power generation gains over time and varying temperatures. A note: this conclusion doesn’t extend to P-type IBC batteries in this study.
HJT Hurdles: Heterojunction components face challenges, evident in oxidized and blackened solder ribbons. Despite a higher operating temperature, the attenuation rate remains consistent at 9.37%. A sign that heterojunction manufacturing still has room to grow.
A Note of Caution:
While this data offers insights, it’s a snapshot. Different batches may yield different results, and tech is always on the move. The solar horizon holds endless possibilities. ☀️🔍 #SolarInnovation #RenewableEnergy #TechStudy
