PROS AND CONS

A solar cell, or photovoltaic cell, is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect.

MADE BY CZOCHRALSKI

METHOD

CUT INTO WAFERS FOR OPTIMIZING

PERFORMANCE AND SHAPE

SPACE EFFICIENT

LONG LIFE SPAN

CONVEERTS MORE THAN 22%

OF SUNLIGHT INTO ELECTRCITY

Silicon is melted and poured into a square

mold, which is cooled and cut into perfectly

square wafers.

13-16% EFFICIENY

MANUFACTURING PROCESS SIMPLE AND

CHEAP

LOWER SPACE EFFICIENCY

LOWER HEAT TOLERANCE

A thin-film solar cell is a second generation solar cell that is made by depositing one or more thin layers, of photovoltaic material on a substrate, such as glass,

plastic or metal.

Amorphous silicon Cadmium Telluride Copper indium gallium

Solar cells Solar cells arsenide solar cells

•Only 1% of the silicon used in crystalline silicon solar cells is required in amorphous silicon solar cells.

•Output of electrical power is low.

•Used for small-scale applications such as in pocket calculators

•Less cost than conventional solar cells made up of silicon.

•Efficiency varies in range of 9-11%

•Can be easily Manufactured

•Cadmium is present in abundant amount.

• Semiconductor materialComposed of Copper

,Indium, gallium and selenium.

•Efficiency varies in range of 10-12%

•Contain less amounts of the toxic material.

•Light Weight Solar cells

A dye-sensitized solar cell is a low-cost solar cell. It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte.

An organic solar cell is a type of photovoltaic that uses organic electronics, a branch of electronics that deals with conductive organic polymers or small organic molecules for conversion

Principle :- Photovoltaic Effect
