This paper reports the measurement of the junction temperature and the determination of the thermal resistance of the single-crystal-silicon solar cell under the dark and illuminating conditions, respectively. Under the dark condition, the solar cell is considered as a conventional p-n junction and is subject to a reverse current in order to …

In materials science, a single crystal (or single-crystal solid or monocrystalline solid) is a material in which the crystal lattice of the entire sample is continuous and unbroken to the edges of the sample, with no grain boundaries. [1] The absence of the defects associated with grain boundaries can give monocrystals unique properties, particularly mechanical, …
These types of solar cells are further divided into two categories: (1) polycrystalline solar cells and (2) single crystal solar cells. The performance and efficiency of both these solar cells is almost similar. The silicon based crystalline solar cells have relative 4.2.9.2
Outdoor exposure tests of a solar cell have been conducted at the University of Brunei Darussalam once a week for a period of six months. These data were used to estimate the efficiency η and fill factor FF of the solar cell using well known equations (1–12). The I ...
In order to improve the efficiency of the scintillation crystal testing, we present a crystal testing device that has 1) list-mode data output for the random radiation events, and 2) richer spatial information than the single channel recording devices to achieve multiple crystal measurement, and 3) good practicability, stability and expansibility. The device …

Perovskite single-crystal thin films (SCTFs) have emerged as a significant research hotspot in the field of optoelectronic devices owing to their low defect state density, long carrier diffusion length, and high environmental stability. However, the large-area and high-throughput preparation of perovskite SCTFs is limited by significant challenges in …
The fracture strengths of single crystal Si at strain rates of 500−700 s −1 for loading along different crystallographic directions are plotted in Fig. 2, along with fitting with the Weibull distribution (Eq. (4)).Sample type #1 (m = 8.6, σ 0 = 1184 MPa) exhibits a higher Weibull modulus, but a lower characteristic fracture strength than sample type #2 (m = …
