Photovoltaic cells are semiconductor devices that can generate electrical energy based on energy of light that they absorb.They are also often called solar cells because their primary use is to generate electricity specifically from sunlight, but there are few applications where other light is used; for example, for power over fiber one usually uses laser light.
The development of the photovoltaic technology of solar cells can be tracked across four generations . Covering the period from when the first practical solar cell was invented in 1954 to the 1990s, the first generation refers to the early developments and commercialization. Conventional silicon cells made of monocrystalline and polycrystalline silicon and gallium

Employing sunlight to produce electrical energy has been demonstrated to be one of the most promising solutions to the world''s energy crisis.

Photovoltaic cells consist of two or more layers of semiconductors with one layer containing positive charge and the other negative charge lined adjacent to each other. Sunlight, consisting of small packets of energy termed as photons, strikes the cell, where it is either reflected, transmitted or absorbed. When the photons are absorbed by the negative layer of the photovoltaic cell, the

Recycling of PV comprises repairing, direct reuse, and recycling of materials chemically and mechanically from different types of decommissioned photovoltaic modules.
The recycling of photovoltaic modules can be segmented into two steps. In the first step the solar cell is separated from the glass and EVA layer. In the second step the solar cell is refined by removing the metallization portion, ARC layer, and p-n junction.
The disassembly and recyclability of the end-of-life solar cells is not really deliberated because of the deficiency of solar panels recycling plants worldwide. Recyclability of the expired solar cells can decrease the production cost of new systems.
The recycling strategy for the photovoltaic module was introduced in the 1990 s . Recycling solar cells is crucial for the economy as 55% of renewable energy is fulfilled by it, compared to 28% and 11% contribution of wind and hydropower respectively . Intact silicon (Si) wafer recovery should be kept on priority.
Recycling is attempted to develop a safe and cost-effective process for the disposal of PV solar panels. Reclaiming of such materials keeps precious natural resources from being depleted. Now companies can see the potential benefits out of recycling of PV panels . 8. Waste composition and generation
Recycling of end-of-life photovoltaic modules (PVMs) attracts the attention of researchers due to valuable materials present in it. With the advances in the PVM manufacturing newer materials are used recently, including silicon wafer and thin film solar cells dominate the market and are key PVM categories requiring recycling.
While the recycling of waste PV modules has already begun to be commercialized, various technologies for PV module recycling are under development in order to improve process efficiency, economics, recovery and recycling rates, and environmental performance. 1.
