The objective of this research was to achieve the most optimal battery depth of discharge based on the characteristics of a cycling battery in an SSPVB. The results indicate that the optimal DOD value for the battery in the solar PV system being investigated is 70%, with LLP = 0% and COE = 0.20594 USD/kWh.
The proposed model includes the depth of discharge (DOD) of the battery, which is determined based on the battery life loss cost. In addition, in the optimal model, the amount of energy flow from the battery bank during the charging and discharging cycles must satisfy the load demand at the lowest cost and with the highest reliability.
Turning to the results, the conversion efficiency of c-Si solar cells has a maximum at a given value of the thickness, which is in the range 10–80 µm for typical parameters of non-wafer-based silicon.
The efficiency limits can be calculated by solving the transport equations in the assumption of optimal (Lambertian) light trapping, which can be achieved by inserting proper photonic structures in the solar cell architecture. The effects of extrinsic (bulk and surface) recombinations on the conversion efficiency are discussed.
Ultimately, the conversion efficiency of LILT solar cell is 31.5 ± 0.5% (AM0, 25 °C) and 34.3 ± 0.5% (1/9AM0, − 100 °C), respectively. Furthermore, the changes of electrical parameter before and after radiation at different temperatures have been presented, including temperature coefficient of Voc and Isc and the degradation of max-power.
Photovoltaic (PV) conversion of solar energy starts to give an appreciable contribution to power generation in many countries, with more than 90% of the global PV market relying on solar cells based on crystalline silicon (c-Si). The current efficiency record of c-Si solar cells is 26.7%, against an intrinsic limit of ~29%.
