Abstract Thin film Si solar cell and surface plasmon polaritons (SPPs) effects on solar cell efficiency, series resistance and shunt resistance are studied and analyzed in this work. The different surface plasmon polaritons (SPPs) shapes and their effects on the optical, electrical properties and therefore on the efficiency of thin film solar cell are studied in this work. This study is introduced using 3D numerical simulation results. The semiconductor and electromagnetic models are incorporated for studying the electrical and optical behaviors of the thin film solar cells, respectively. A 14.76% efficiency is obtained for triangle’ SPPs of about 1.07% of efficiency improvement compared to solar cell of SPPs free. The solar cell electrical parameters also are extracted in this work based on a single diode equivalent model. The series resistance is enhanced for solar cells of equilateral triangle SPP by 3% compared to the non-applied SPPs.

Experimental and theoretical study Porphyrin-grafted ZnO nanowire arrays were investigated for organic/inorganic hybrid solar cell applications. Two types of porphyrin – Tetra (4-carboxyphenyle) TCPP and meso-Tetraphenylporphine (Zinc-TPP)were used to modify the nanowire surfaces. The vertically aligned nanowires with porphyrin modifications were embedded in graphene-enriched poly (3-hexylthiophene) [G-P3HT] for p-n junction nanowire solar cells. Surface grafting of ZnO nanowires was found to improve the solar cell efficiency. There are different effect for the two types of porphyrin as results of Zn existing. Annealing effects on the solar cell performance were investigated by heating the devices up to 225 °C in air. It was found that the cell performance was significantly degraded after annealing. The degradation was attributed to the polymer structural change at high temperature as evidenced by electrochemical impedance spectroscopy measurements.

CdTe is a very robust and chemically stable material and for this reason its related solar cell thin film photovoltaic technology is now the only thin film technology in the first 10 top producers in the world. CdTe has an optimum band gap for the Schockley-Queisser limit and could deliver very high efficiencies as single junction device of more than 32%, with an open circuit voltage of 1 V and a short circuit current density exceeding 30 mA/cm2. CdTe solar cells were introduced at the beginning of the 70s and they have been studied and implemented particularly in the last 30 years. The strong improvement in efficiency in the last 5 years was obtained by a new redesign of the CdTe solar cell device reaching a single solar cell efficiency of 22.1% and a module efficiency of 19%. In this paper we describe the fabrication process following the history of the solar cell as it was developed in the early years up to the latest development and changes. Moreover the paper also presents future possible alternative absorbers and discusses the only apparently controversial environmental impacts of this fantastic technology.
