As the world gears towards more sustainable and broadly available energy, solar PV is attaining tremendous gains in the power industry. A solar power plant is reliant on the conversion of energy from the sun into electricity, either directly using photovoltaic (PV), or indirectly using concentrated solar power (CSP). Photovoltaics’ a simple and unique way of harnessing the sun's energy. PV modules (solar cells) are unique as they directly convert the incident solar radiation into electricity without noise or pollution as obtained in conventional power generating techniques making them robust, reliable, and long-lasting. This past decade has witnessed various advancements in efficiency of solar cells which has culminated in increased efficiency, current, and reduced overall costs. This article furnishes an in-depth review on PV systems, modules, and latest trends in solar cell line technologies like PERC, Topcon, Heterojunctions cells with efficiencies ranging from 20% - 29%. This paper further examines cell manufacturing processes and PV technology of solar modules (monofacial and bifacial) and their performance based characteristics.
