Product Description
What is TOPCon solar panel?
TOPCon, short for 'Tunnel Oxide Passivated Contact', is a more advanced N-type silicon cell technology. The concept was first proposed by the German solar research institution Fraunhofer ISE back in 2014. It was not until 2019 that the technology was scaled.TOPCon: Beyond PERC Cell Technology
y 2019, three years after it was widely adopted by the solar industry and more than three decades after its invention by Australian scientist Martin Green in 1983, the PERC solar cell technology had became the dominant solar cell technology. In 2019, PERC solar cells held 65% of the market share. In just a year, it had sliced the share held by the more conventional back surface field (BSF) solar cell technology to slightly less than 32% globally from the 83% it held in 2017.After years of continuous R&D efforts towards optimizing the technology, the efficiency improvement potential of PERC now seems to have been exhausted. At 23%, manufacturers have approached the theoretical upper limit imposed by scientific research on the efficiency of PERC cells, at 24.5%. Further optimization of the technology now seems elusive and since 2021, manufacturers have been looking beyond it to:
In a TOPCon cell, a tunnel oxide layer and an intrinsically polysilicon layer is added to the rear side. The front side is passivated by a dielectric stack of passivation and anti-reflection layer. Presently, the mainstream process grows a 1.5-2cm tunnel oxide layer through thermal oxidation, while a sediment 150-200nm of intrinsically polysilicon layer is added through a chemical depositing process known as LPCVD, and the cell is then doped through phosphorus diffusion.

A solar panel's first line of defence against the harsh environment is the packaging. A typical solar panel packaging consists of a cardboard box with the footprint of a pallet and houses between 26 to 36 panels in the box. A good solar panel packaging design makes it easier to transport solar panels on a pallet, and provide excellent protection to the panels during transport.
Offers professional consulting services, professional knowledge of PV power plant and charging station solutions, and full life cycle O&M capabilities. How Do Solar Panels Work?
Solar panels collect clean renewable energy in the form of sunlight and convert that light into electricity which can then be used to provide power for electrical loads. Solar panels are comprised of several individual solar cells which are themselves composed of layers of silicon, phosphorous (which provides the negative charge), and boron (which provides the positive charge). Solar panels absorb the photons and in doing so initiate an electric current. The resulting energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their atomic orbits and released into the electric field generated by the solar cells which then pull these free electrons into a directional current. This entire process is known as the Photovoltaic Effect. An average home has more than enough roof area for the necessary number of solar panels to produce enough solar electricrity to supply all of its power needs excess electricity generated goes onto the main power grid, paying off in electricity use at night.
In a well-balanced grid-connected configuration, a solar array generates power during the day that is then used in the home at night. Net metering programs allow solar generator owners to get paid if their system produces more power than what is needed in the home. In off-grid solar applications, a battery bank, charge controller, and in most cases, an inverter are necessary components. The solar array sends direct current (DC) electricity through the charge controller to the battery bank. The power is then drawn from the battery bank to the inverter, which converts the DC current into alternating current (AC) that can be used for non-DC appliances. Assisted by an inverter, solar panel arrays can be sized to meet the most demanding electrical load requirements. The AC current can be used to power loads in homes or commercial buildings, recreational vehicles and boats, remote cabins, cottages, or homes, remote traffic controls, telecommunications equipment, oil and gas flow monitoring, RTU, SCADA, and much more.
