摘要

India is a country where the government has taken good initiatives to increase renewable energy. They are focusing especially on solar-based electricity, i.e., out of 175 GW by 2022, 100 GW will be produced by solar-based power plants. They may be rooftop, building integrated, ground-mounted or solar thermal based. As per available data in February 2020, India has 34 GW installed capacity w.r.t. to the target of 100 GW. India is a country with a very high population density therefore land scarcity is always a problem in the present scenario. To generate power from solar PhotoVoltaic (PV), land is a very essential prime requirement [1, 2]. In the era of progress in solar cell material technology, solar cells and solar PV modules are manufactured from various types of technologies like c-Si, mc-si, amorphous si, thin-film, and Heterojunction technology [3]. Although c-si, mc-si are the two most mature technology and used widely, however, they suffer from the problem of power loss in high-temperature zones. India is a country with several kinds of temperature zones hence to install the PV based projects with conventional module technology leads to economical and technical barriers [4]. It seems less significant to compare the power drop of PV modules of small ratings but since nowadays multiples modules are connected to achieve a large amount of power so in the strings meaningful voltage drop is observed. This voltage drop makes the system less stable and more sensitive [5, 6]. Researchers are continuously searching the option for more efficient and less temperature-sensitive materials for making solar cells. In this sequence various types of materials based like amorphous si, thin-film exist but suffer from low-efficiency problems in contrast to the better performance at high temperatures. The hetrojunc-tion (HIT) technology-based solar cells are also in the developing phase and yet to be commercialized. The rejection or selection of technology should not be a blind procedure, it should be judged on the available natural parameters at the local site[7-10].
