Currently, most solar photovoltaic modules are made of crystalline silicon (c-Si) solar photovoltaic modules made of polycrystalline silicon and monocrystalline silicon. In 2013, crystalline silicon accounted for more than 90% of global photovoltaic production, while the rest of the entire market was composed of thin-film solar photovoltaic module technologies using cadmium telluride, CIGS, and amorphous silicon. So what is the technology of solar photovoltaic modules? Let us take a look at it next.

Here is the content list:

  • Emerging third-generation solar photovoltaic module technology

  • Thin-film solar photovoltaic module technology

  • Smart solar photovoltaic module

Emerging third-generation solar photovoltaic module technology

The emerging third-generation solar photovoltaic module technology uses advanced thin-film cells. Compared with other solar photovoltaic module technologies, they produce relatively high-efficiency conversion at a low cost. In addition, solar photovoltaic modules on spacecraft preferably use high-cost, high-efficiency, and closely-packed rectangular multi-junction cells because they provide the highest power generation ratio per kilogram liter into space. Solar photovoltaic module cells are compound semiconductors, made of gallium arsenide (GaAs) and other semiconductor materials. Another emerging photovoltaic technology that uses cells is concentrated solar photovoltaic modules.

Thin-film solar photovoltaic module technology

In rigid thin-film solar photovoltaic modules, the cells and solar photovoltaic modules are manufactured on the same production line. Solar photovoltaic modules are created on glass substrates or superstrates and create electrical connections in situ, the so-called "monolithic integration". The substrate or superstrate is laminated to the front or back panel with a sealant, usually another piece of glass. The main solar photovoltaic module technology in this category is CdTe, or a-Si, or a-Si+uc-Si tandem, or CIGS (or variants). The solar conversion rate of amorphous silicon is 6-12%. By depositing a photosensitive layer and other necessary layers on a flexible substrate, flexible thin-film cells and solar photovoltaic modules can be created on the same production line. If the substrate is an insulator (such as polyester or polyimide film), monolithic integration can be used. If it is a conductor, another solar photovoltaic module electrical connection technology must be used. Solar photovoltaic modules are assembled into solar photovoltaic modules by laminating them to a transparent colorless fluoropolymer (usually ETFE or FEP) on the front side and a polymer suitable for bonding to the final substrate on the other side.

Smart solar photovoltaic module

Many companies have begun to embed electronic products into solar photovoltaic modules. This makes it possible to perform MPPT for each solar photovoltaic module individually and measure performance data for monitoring and fault detection at the solar photovoltaic module level. Some of these solutions use power optimizers, a converter technology designed to maximize the power harvesting of solar photovoltaic module systems. By 2010, this electronic device can also compensate for the shadow effect, where the shadow on a part of the solar photovoltaic module will cause the electrical output of one or more battery strings in the solar photovoltaic module to drop to zero, but there is no solar photovoltaic module. The output of the entire module is reset to zero.
