Sun is the provenance of all kinds of energy prevailing on earth since ages. Being renewable and pollution free, solar energy has paved the way to compensate the exploitation of non-renewable sources of energy through the discovery of solar/photovoltaic cells. Considerable developments have been witnessed in solar cells with the passage of time which not only resulted in their compact sizes but also resulted in increased power conversion rate. This paper presents comparative analysis of photovoltaic through a detailed study of constructions, applications and efficiencies of the solar cells of third generation including their future trends and aspects. Among all types of solar cells, till date concentrated solar cells have shown maximum efficiency of 38.9%.

太阳是自古以来在地球上盛行的各种能源的起源。太阳能是可再生的且无污染的，已经通过发现太阳能/光伏电池为补偿不可再生能源的开发铺平了道路。随着时间的流逝，已经见证了太阳能电池的显着发展，这不仅导致了其紧凑的尺寸，而且还导致了功率转换率的提高。本文通过对第三代太阳能电池的结构，应用和效率的详细研究（包括其未来趋势和方面），对光伏技术进行了比较分析。迄今为止，在所有类型的太阳能电池中，集中式太阳能电池的最高效率已达到38.9％。
