The purpose of this article is to understand the state of art of photovoltaic solar energy through a systematic literature research, in which the following themes are approached: ways of obtaining the energy, its advantages and disadvantages, applications, current market, costs and technologies according to what has been approached in the
The power output of the solar photovoltaic module decreases with an increase in its operating temperature. Thus, maintaining lower operating temperatures for solar photovoltaic modules is critical for achieving the desired higher output. Although several cooling strategies for PV modules have been documented in the literature, commercially suitable cooling systems
Solar-cell efficiency is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the system.
In this study, two different types of photovoltaic panels such as monocrystalline and polycrystalline solar panels are examined experimentally and the performance of these panels are assessed.
The results suggest that for ideal solar cells with neutral colors that have lightness over 80, the highest efficiency could range between 20.4 % and 25.9 %, with an optimum bandgap between 0.95 and 1.15 eV. The absolute value of over 2 % in efficiency could be further improved if the optimal reflectance is applied to minimize efficiency loss.
