Are crystalline silicon solar cells a good photoelectric conversion efficiency?

Figure 3.43 presents the trend of photoelectric conversion efficiency of crystalline silicon cells over the past few years. It is revealed that the ideal photoelectric conversion efficiency of silicon solar cells still cannot be achieved.

What is the basic structure of crystalline silicon solar cells?

Basic structure of crystalline silicon solar cells. The fabrication of crystalline silicon solar cells consists of three main processes, i.e., preparing a junction by diffusion, vapor deposition of an anti-reflection film, and electrode preparation).

What type of crystals are used in solar cells?

For solar cell technology, P-type (resistivity 0.1–1 Ω cm) single crystals with <100> orientation with a diameter of between 170 and 220 mm and mass of up to 200 kg are mostly used . N-type single crystals are prepared for some types of high efficiency solar cells.

Do polycrystalline silicon solar cells apply to standardized processes?

Polycrystalline silicon solar cells may not apply to standardized processes for certain special properties. Some alternatives to the standard process have been proposed, while they have not been adopted for their relatively high cost. People are still looking for a solution, two of which are not the same as the single crystalline silicon process.

Why are hit solar cells more economical than ordinary crystalline silicon solar cells?

The mentioned good cell characteristics make it more economical than ordinary crystalline silicon solar cells at the identical output of power generation. In 2009, the photoelectric conversion efficiency of HIT solar cells in the laboratory reached 23.0%.

How efficient are monocrystalline solar cells?

Monocrystalline solar cells reached efficiencies of 20% in the laboratory in 1985 (ref. 238) and of 26.2% under 100× concentration in 1988 (ref. 239). In this period, the efficiency of industrial solar cells slowly grew from 12% to 14.5%.
