Special Issue Information

Dear Colleagues,

With each passing day, the effects, damage, and danger of scientific alerts to global warming become more prescient. One of the most hopeful developments has been the increasing use of photovoltaic solar electric generation through large-scale photovoltaic power installations, as well as the increased numbers of these installations made economically viable through low-cost Asian solar cells. The development of thinned silicon solar cells and more marine, recreational, and portable small-scale off-grid applications clearly shows that sustainable photovoltaic power generation can compete and win economically against the established fossil fuel industry. With the help of your submissions of papers concerning research and advances in this topic, this Special Issue of Applied Sciences, entitled “Advances in Solar Photovoltaic Technologies”, hopes to explore the applications and innovations supporting the continued growth and economic viability of photovoltaic solar electric generation. Applied Sciences is a high-impact journal that will communicate your research with the scientific community and pioneers well-positioned to benefit from, build upon, and implement novel approaches and technologies. No novel application is too small or too large for consideration, and every research topic or innovation in materials, solar cell design, or configuration that may lead to reduced cost and/or more widespread applications is welcomed for consideration.

Solar systems connected to the grid are crucial in addressing the global energy crisis and meeting rising energy demand. The efficiency of these systems is totally impacted by varying weather conditions such as changes in irradiance and temperature throughout the day. Additionally, partial shading (PS) adds to the complexity of the nonlinear characteristics of photovoltaic (PV) systems, leading to significant power loss. To address this issue, maximum power point tracking (MPPT) algorithms have become an essential component in PV systems to ensure optimal power extraction. This paper introduces a new MPPT control technique based on a novel reptile search optimization algorithm (RSA). The effectiveness of the proposed RSA method is evaluated under different weather conditions with varying irradiance and partial shading. The results of the RSA algorithm are compared to other existing bio-inspired algorithms and show superior performance with an average efficiency of 99.91%, faster dynamic response of 50 ms, and less than 20 watts of oscillation. The RSA-MPPT based technique provides higher efficiency, faster settling time, and minimal oscillation around the maximum power point (MPP), making it a reliable solution for effective solar power harvesting.

The necessity for further growth in the demand for electricity, particularly in the remote countryside, has been essential to Algeria’s economic and social progress in recent years. The Saharan regions account for around 80% of Algeria’s surface and have significant power demands. These areas are distinguished by their scattered population, extremely hot weather with high radiation levels (7 kw h/m2/day), and minimal energy use. Photovoltaic technology is one of the finest ways to harness solar power. The conversion of radiant energy (light quanta) into electrical energy can be achieved with the use of semiconductor materials. The effects of a solar cell depend on parameters such as solar cell technology, the position of the photovoltaic array, climate, and geographic data of the site. This paper presented: the role of site choice in the production of photovoltaic electricity. The results obtained for five sites in Algeria: Ouargla, Algers, Bechar, Sidi Bel Abbès, and Batna, confirmed that desert sites (Ouargla, Bechar) have a good photovoltaic efficiency result with large solar power irradiance.
