Explore our top-performing monocrystalline, flexible, and high-efficiency double-glass photovoltaic modules engineered for diverse application scenarios.
The global transition toward carbon neutrality has accelerated technological innovation within the solar photovoltaic (PV) market. Among these innovations, Heterojunction Technology (HJT) has emerged as one of the most promising cell architectures, succeeding traditional Passivated Emitter and Rear Cell (PERC) and competing alongside Tunnel Oxide Passivated Contact (TOPCon) systems. HJT merges the benefits of crystalline silicon (c-Si) with thin-film silicon, depositing amorphous silicon (a-Si) layers on both sides of an N-type monocrystalline wafer.
From a physics standpoint, HJT cells benefit from an extremely effective passivation layer structure. The core substrate is a high-lifetime N-type CZ monocrystalline silicon wafer. An ultra-thin layer of intrinsic amorphous silicon (i-a-Si) is deposited on both faces, followed by oppositely doped layers of amorphous silicon (P-type and N-type) to establish the p-n junction and back-surface field. This symmetrical structure reduces surface recombination velocity to single-digit cm/s levels, leading to high open-circuit voltages (Voc > 750 mV). A Transparent Conductive Oxide (TCO) layer, typically Indium Tin Oxide (ITO), is then deposited to facilitate lateral carrier collection and light incoupling, finished with low-temperature copper or silver grid lines.
Unlike PERC and TOPCon which require multiple high-temperature oxidation and diffusion processes exceeding 800°C, HJT manufacturing processes are kept under 200°C. This low-thermal budget minimizes wafer warping and allows for wafers thinner than 110 micrometers, significantly reducing the carbon footprint of production and driving down raw material costs.
When selecting a supplier for large-scale utility projects, commercial and industrial (C&I) developments, or high-end residential systems, assessing the technical capabilities and bankability of top manufacturers is critical. Here is an overview of the top 10 global leaders currently driving HJT production capacity and technology development:
