What is an Amorphous Silicon Solar Cell? Amorphous Solar Panels Advantages and Disadvantages

Amorphous silicon solar cells are thin-film solar cells based on amorphous silicon compounds. According to different materials, current silicon solar cells can be divided into three categories: monocrystalline silicon solar cells, polycrystalline silicon thin film solar cells and amorphous silicon thin film solar cells.

Indoor Solar Panels 

Advantages of amorphous solar cells
1. Low production cost: Due to the low reaction temperature, it can be manufactured at a temperature of about 200 °C, so films can be deposited on glass, stainless steel plates, ceramic plates, and flexible plastic sheets, which are easy to produce in large areas and have low costs.

2. Short energy return period: Amorphous silicon solar cells with a conversion efficiency of 6% use about 1.9 kWh/W of electricity for production, and the time to return the above energy after generating electricity is only 1.5-2 years.

3. Suitable for mass production: Amorphous silicon material is formed by vapor deposition, and the commonly used method is plasma enhanced chemical vapor deposition (PECVD) method. This manufacturing process can be continuously completed in multiple vacuum deposition chambers, thereby realizing mass production. The main process (PECVD) of amorphous silicon solar cells using glass substrates is similar to that of TFT-LCD array production, and the production methods have the characteristics of high degree of automation and high production efficiency.

In terms of manufacturing methods, there are electron cyclotron resonance method, photochemical vapor deposition method, DC glow discharge method, radio frequency glow discharge method, sputtering method and hot wire method. In particular, the radio frequency glow discharge method has become an internationally recognized mature technology because of its low temperature process (~200 °C), which is easy to achieve large-scale and large-scale continuous production.

4. Good high temperature performance: when the working temperature of the solar cell is higher than the standard test temperature of 25 °C, its optimal output power will decrease; the temperature of the amorphous silicon solar cell is much less affected by the temperature than the crystalline silicon solar cell.

5. Good response to weak light and high charging efficiency: The absorption coefficient of amorphous silicon material is in the entire visible light range, and it has a good adaptability to low light and strong light in actual use.

The above-mentioned unique technical advantages make thin-film silicon cells have broad application prospects in the civilian field, such as photovoltaic building integration, large-scale low-cost power stations, and solar lighting sources.

Disadvantages of amorphous silicon solar cells
The industry has had doubts about amorphous silicon thin-film solar cells before, mainly because of their low cell conversion efficiency (5%-9%), and extremely fast decay, with a limited service life of only 2-3 years.

With the advancement of technology, the current mainstream amorphous silicon thin film solar cells have a service life of more than 10 years. This makes amorphous silicon thin-film solar cells one of the most promising thin-film cell technologies at present.

What is an Organic Solar Cell?

Detailed explanation of the characteristics and structural principles of organic solar cells

Organic solar cells are solar cells that consist of organic materials at the core. It is mainly based on organic materials with photosensitive properties as semiconductor materials, and the photovoltaic effect generates voltage to form a current to achieve the effect of solar power generation.

Custom Solar Panels

First, the characteristics of organic solar cells

As a new type of solar cell device, organic solar cells have the characteristics of flexibility, light weight, adjustable color, solution processing, and large-area printing preparation. They are currently a hot spot in the field of solar cell research. But low efficiency is the main reason that limits its large-scale application.

Second, the structural principle of organic solar cells

1. The principle of organic solar cells

Organic solar cells use photosensitive organics as semiconductor materials, and generate voltages to form currents by the photovoltaic effect. The main photosensitive organic materials have conjugated structure and conductivity, such as phthalocyanine compounds, porphyrins, cyanines, etc.

2. Several structures of organic solar cells

Organic solar cells can be divided into single junction structure, P-N heterojunction structure, and dye-sensitized nanocrystalline structure according to semiconductor materials.

3. Single junction structure

The single-junction structure is an organic solar cell made based on the principle of Schottty barrier. Its structure is glass/metal electrode/dye/metal electrode, which uses the different work functions of the two electrodes to generate an electric field. Electrons are transferred from the metal electrode with low work function to the electrode with high work function to generate photocurrent. Since electrons and holes are all transferred in the same material, the photoelectric conversion rate is relatively low.

4. P-N heterojunction structure P-N

The heterojunction structure refers to a heterojunction structure with a donor-acceptor (N-type semiconductor and P-type semiconductor). Among them, semiconductor materials are mostly dyes, such as phthalocyanine compounds and perylene tetraformaldehyde imine compounds, using the D/A interface (Donor—donor, Acceptor—acceptor) and electron-hole separation between semiconductor layers. The transfer characteristics in different materials increase the separation efficiency. Elias Stathatos and others combined the advantages of inorganic and organic compounds to make solar cells with a photoelectric conversion rate of 5% to 6%.

5. NPC (nanocrystaline photovoltaic cell) dye-sensitized nanocrystals

Dye-sensitized solar cell (DSSC) mainly refers to a type of solar cell that uses dye-sensitized porous nanostructured TiO2 film as the photoanode. It is a solar cell that mimics the photosynthesis principle of plant chlorophyll. However, NPC solar cells can choose appropriate redox electrolytes to increase the photoelectric efficiency, which can generally be stabilized at 10%, and nanocrystalline TiO2 is easy to prepare, low in cost, and has a considerable life span, which has a good market prospect.
