What is the smallest size a solar panel can be made?

Introduction What is the smallest size a solar panel can be made? 295*295mm, 10W. Conventional solar cells usually have a structure consisting of two layers of glass with EVA material and cells in between.

What is the smallest size a solar panel can be made?

295*295mm, 10W.

Conventional solar cells usually have a structure made of EVA material and cells located between two layers of glass are heavier and require supports during installation, making them difficult to move.

Flexible thin-film solar cells do not require glass backsheets or covers and are 80% lighter than double-layer glass solar cell modules. Flexible cells using PVC backsheets and ETFE film covers can even be bent as desired. , easy to carry. No special supports are required during installation and it can be easily installed on the roof or on top of a tent.

Detailed information

Principle of energy production

Solar cell is a device that reacts to light and can convert light energy into electricity. There are many types of materials that canproduce photovoltaic effects, such as: monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, copper selenium indium, etc. Their principles of energy production are basically the same. Today, crystalline silicon is used as an example to describe the photovoltaic power production process. Crystalline P-type silicon is doped with phosphorus to obtain N-type silicon, forming a P-N junction.

When light irradiates the surface of the solar cell, part of the photons are absorbed by the silicon material; the energy of the photons is transferred to the silicon atoms, causing the electrons to transition and become free electrons. accumulate on both sides of the P-N junction to form a potential difference, when the external circuit is connected, under the action of this voltage, a current will flow through the external circuit to pproduce a certain output power. The essence of this process is: the process of converting photon energy into electrical energy.
