Abstract The characteristics of two-junction solar cells were calculated in this work, in which phosphides of group III are used as the top junction, and Si as the bottom junction. The following ternary phosphide compounds Ga0.52In0.48P (1.85 eV), GaPN0.02 (1.9 eV), and GaPN0.04 (1.7 eV) were considered as the active material of the top junction. The use of GaPN0.04 allowed one to reach the current matching with the bottom Si junction and an efficiency of 30% was achieved. In addition, the influence of the layer thickness, the lifetime of minority charge carriers and the electronic affinity on the efficiency of solar energy conversion were considered.

<p class="TTPAbstract">Blend of conjugated polymer poly(3-hexylthiophene) or P3HT and Zinc Oxide nanoparticles (ZnO-NP) has been intensively used as active material for high performance hybrid solar cells.

Capping of ZnO-NP is currently applied to avoid this agglomeration effect.

The measurement was carried out with light irradiation of 532 nm and temperature ranging from 78 to 300 K.  The spectra were analyzed by a bimolecular carrier recombination method with Arrhenius activation energy. Two parallel charge carrier recombination processes are observed, namely polarons recombination along polymer chain (intra-chain) and inter-chain polarons recombination in the P3HT-chains. At low temperatures, polarons recombine along polymer chains (intra-chain) with activation energy between 19-23 eV for all samples. However, the inter-chain polaron motion is influenced by capping agents as shown by a variation in its activation energy ranging from 28 to 58 eV.</p>

Purpose The aim of this paper is to apply a watery infrared filter for silicon solar cell efficiency enhancement in Kerman province of Iran as a talent region for solar energy production. Design/methodology/approach With this research, the water is applied as a filter for silicon solar cells in different volumes and thicknesses. Findings The obtained results showed that using various amounts of water could be a suitable choice for increasing the efficiency of silicon solar cells. Originality/value Other wavelength regions just cause the increase in the entropy and decrease in the efficiency. With this research, the water is applied as a filter for silicon solar cell in different volumes and thickness. The obtained results showed that using different thicknesses of water could be suitable choice for increasing the efficiency of silicon solar cell.

In this work, a silicon solar cell HIT (heterojunction with intrinsic thin-layer) a-Si:H(n)/a-Si:H(i)/c-Si(p) was simulated using AFORS-HET software. The influence of layer thickness and temperature of the solar cell under study on its photovoltaic characteristics is discussed. When optimizing the above characteristics, its effectiveness reaches a value of 19.1%. The results obtained are the foundation for further scientific and technological research on the development of highly efficient silicon solar cells.
