We supply the world's most advanced photovoltaic cell technologies — N-type TOPCon, bifacial, half-cut, and back contact — plus complete solar solutions, all sourced from certified global manufacturers.
Tunnel Oxide Passivated Contact (TOPCon) is the current pinnacle of mass-produced solar cell technology. Our N-type TOPCon cells achieve conversion efficiencies exceeding 26.3% — significantly ahead of legacy PERC technology — while delivering superior reliability across a 25+ year operating lifetime.
With zero light-induced degradation (LID), an industry-low temperature coefficient of -0.30%/K, and strong low-light response, these cells generate more energy per installed watt — translating directly into improved returns on every project.
Bifacial solar cells harvest sunlight from both the front and rear surfaces, capturing reflected and diffuse radiation from the ground and surroundings. With bifaciality exceeding 80%, they consistently deliver 5–20% more energy yield than monofacial equivalents — depending on albedo and installation type.
Ideal for ground-mount utility projects, floating solar, carports, and any installation where rear-side irradiance can be maximised. Compatible with tracker systems for maximum annual generation.
Half-cut cells are full wafers precisely laser-cut to half size. This simple but effective design change cuts resistive power losses by up to 50% versus full-cell equivalents, significantly improving module output and reliability — particularly under partial shading conditions.
Half-cut architecture also improves mechanical durability, reducing micro-crack risk during handling and installation. Available in standard 182mm and 210mm wafer formats, compatible with leading module designs globally.
Back contact cells represent the most advanced commercial solar cell architecture available today. By relocating all metal contacts to the rear of the wafer, the entire front surface is freed from shading — maximising light absorption and pushing conversion efficiency 1–1.5% beyond mainstream N-type cells.
With an ultra-low temperature coefficient of -0.26%/K and exceptional anti-shading performance, BC cells deliver measurably higher energy yield per installation area — making them the preferred choice for premium applications where maximum performance per square metre matters.
Beyond individual cells, we supply complete solar product packages — from high-efficiency modules to system-level configurations for utility, commercial, and residential applications. All products are sourced from certified global manufacturers and configurable to your project's specific performance and format requirements.
Whether you are a module manufacturer, EPC contractor, project developer, or distributor, we can structure supply arrangements to match your volume, timeline, and technical specification. Tell us what you need — we will find the right fit.
N-type TOPCon technology delivers measurable advantages at every metric that matters — efficiency, degradation, temperature behaviour, and long-term energy yield.
