Classification of solar cells.

Classification	Category	Efficiency (%)	Cost	Advantages and disadvantages
Silicon crystalline solar cells (first generation)	Monocrystalline Silicon	27.5	very high	Complex process, good stability
	Polysilicon	23.3	Higher	Simple process, high development potential
	Amorphous Silicon	21.5	High	Simple process, poor stability
Thin film solar cells (second generation)	Cadmium Telluride (CdTe)	22.3	Lower	Serious environmental pollution
	Gallium Arsenide (GaAs)	27.9	very high	Good stability
	Copper Indium Gallium Selenide (CIGS)	23.3	Higher	Shortage of raw materials for preparation
	Inorganic Cell (CZTSSe)	12.5	Low	Simple process, poor stability
New concept solar cells (third generation)	Dye Sensitization (DSSC)	12.3	Lower	Severe pollution, poor stability
	Quantum dot sensitization (QDSC)	16.7	Low	Low efficiency, good stability
	Calcium Titanite (PSCs)	25.1	Low	Simple process, poor stability
