The introduction of Se induced band gap gradients have been shown to be a promising path for improving CdTe devices. Controlling maximum selenium concentration during deposition should allow for better device performance. In this work electron beam induced current maps were measured for CdSeTe/CdTe devices with as-grown selenium concentration between 0 and 20 percent. Results show a collection profile which has not been seen before in similar devices. EBIC results and several interpretations are presented.

The PVSPEC model of spectral mismatch factor (SMM) for photovoltaic modules was developed using spectral irradiance and other meteorological data from eight locations. PVSPEC depends on clear sky index and absolute air mass. Cross-validation was used to evaluate model performance: the model was trained on data from seven locations and tested on data from the remaining location, going through all permutations. Root mean square errors on SMM were 3.2% on average, while absolute errors on long-term spectral effects were 0.8% on average. PVSPEC outperformed existing models developed by First Solar and by the European Commission's Joint Research Center.

In this study, a high-quality TiO2compact layer (CL) is prepared by Spray Pyrolysis Deposition (SPD), which is employed as a potential ETL for the realization of PSCs. To optimize the ETL, the thickness of the TiO2-CL is varied from 20 nm to 200 nm with a step size of 20 nm, where the photovoltaic performance of each is systematically computed. The optics of the solar cell is investigated by 3D finite-difference time-domain simulations, where electrical parameters are analyzed through finite element method simulations. The optimized thickness of the TiO2-CL ETL exhibits a maximum energy conversion efficiency of 19.46%. Detailed guidelines for the optimization process and device design are provided.

In this work, performances of silicon solar cells enhancing by plasmonic scattering and coupling of two-dimensional (2-D) indium nanoparticles (In-NPs) sheets (1-3 layers) embedded in SiO2 antireflective coating (ARC) were demonstrated. Raman and absorbance measurements were examined the plasmonic scattering and coupling effects of 2-D In-NPs sheets embedded in SiO2 layer. Optical reflectance and external quantum efficiency were used to characterize the benefit of plasmonic ARC due to with 2-D In-NPs sheets embedded in SiO2. Photovoltaic current density-voltage measurements under AM 1.5G illumination were used to confirm the enhancement of short-circuit current density and conversion efficiency of the silicon solar cells coated with plasmonic ARC which was depended on In-NPs sheets number. Impressive efficiency enhancements of 39.57%, 38.59%, 34.27% for the cells with 3-, 2-, 1-In NPs sheets embedded in SiO2 layer and of 27.13% for the cell with a SiO2 layer without In-NPs sheet were obtained, respectively, compared to the reference cell.

Van der Waals structures made of layered semiconductor materials, such as transition metal dichalcogenides (TMDCs), have been proposed for the development of ultra-thin photovoltaic devices. The main limitation of these solar cells up to now has been their low open-circuit voltage (Voc), which is typically below 0.55 V even for high illumination levels. Recently, we have presented a p-n Mos2 homojunction that exhibits a Voc of 1.02 V under broadband illumination equivalent to 40 suns. The use of substitutionally-doped $p$ and $n$ Mos2 material instead of a heterojunction is crucial to produce a band alignment that enables high Voc. Another important aspect for the realization of large photovoltages in TMDC solar cells is the optimization of metallic contacts. We demonstrate using a simple circuital model that the presence of Schottky barriers at the semiconductor/metal interfaces does not only introduce a non-ohmic series resistance, but also reduces the Voc because the Schottky diodes are photoactive. We characterize the Schottky barrier produced by different metals in combination with $p$ and $n$ Mos2. When p-flakes are deposited directly onto a SiO2/Si substrate, we find that they are depleted from carriers by a surface doping effect. This depletion contributes to aggravate the effect of the p-MoS2/metal Schottky. We show that inserting a flake of hexagonal boron nitride (h-BN) between the p-material and the SiO2 surface eliminates this effect. Given the already demonstrated strong light absorption of TMDC ultra-thin devices, the achievement of high Voc is a turning point in the path towards high-efficiency TMDC solar cells.

The III-V compound solar cells have contributed as space and concentrator solar cells and are important as sub-cells for multi-junction solar cells. This paper reviews progress in III-V compound single-junction solar cells such as GaAs, InP, AlGaAs and InGaP cells. In addition, analytical results for non-radiative recombination and resistance losses in III-V compound solar cells are shown for further understanding and reducing major losses in III-V compound materials and solar cells.

Part of creating a successful solar industry is developing a capable workforce. It has been repeatedly shown that organizations and companies are more productive when they have diverse and inclusive cultures. The solar industry in the U.S. performs well in some aspects (non-white workforce, positive work environment) but drastically under-performs in many others. We discuss these metrics and how this impacts the renewable energy industry and the solar research community. We highlight some initial actions which are necessary to begin to remediate these deficiencies, such as demographic tracking, recruiting strategies, and mentoring. We also present the historical and ongoing efforts to improve the diversity and inclusion of the Photovoltaic Specialists Conference, particularly through the work of this year's Diversity and Inclusion (D&I) oversight committee. This year's D&I committee is implementing diversity tracking, a women's lunch, a diversity lunch, childcare resources, pronouns on badges, gender-neutral restrooms, addressing accessibility issues, and publishing a diversity statement and code of conduct to the PVSC website.

Heat-recovery (HERC) solar cell is a concept of solar cell that converges heat into electricity and enables silicon solar cell to have high efficiency exceeding the Shockley-Queisser limit without requiring fast carrier extraction. In this paper, we show by numerical simulation its robustness against strong non-radiative recombination of the carriers and a positive effect arising from the bandgap reduction in the energy filtering layers.

Gulf Corporation Countries (GCC) are exposed to high levels of solar insolation throughout the majority of the year. Therefore, the use of photovoltaics (PV) is a viable, clean energy source for the GCC region. This paper presents a detailed techno-economic study for the implementation of a grid-connected rooftop photovoltaic and energy storage system (PV-ESS) in the State of Qatar. This study aims to present a detailed cost analysis as well as sizing information for a house in Qatar. A multi-objective optimization that considers generation and load profiles, cost of grid consumption, cost of materials, and house size is presented in the form of Pareto frontier curves. Load modulation is introduced as a method to lower capital expenditure and operational costs. The benefit to a developed country like Qatar is to improve the resilience of the electrical supply and reduce the carbon footprint. The benefit to a developing country is that it brings electricity to individual homes without needing an expensive utility grid. Although this paper is not intended to study energy policy, the techniques presented can be used to recommend energy policies. The results of this study are presented in the form of implementation steps to make rooftop PV-ESS systems feasible in Qatar based on factual information and detailed analysis.
