“…For industrial flat-plate terrestrial silicon PV modules, surface structuring is routinely applied to interconnection ribbons (attached to cell busbars) to improve the optical performance of modules by either scattering the light incident on the ribbon to the module glass from where it is redirected back into the cell or by re-directing incident light directly into the cell. [9][10][11][12][13][14] Metal finger shading can also be minimized by tuning the metal contact shape and/or surface. Kik 15 presented a grid structure with a surface tilt of 15 resulting in a transmittance of 86% with 50% metal coverage.…”

“…However, optimizing the metal grid shapes to enhance light capture under concentrated flux distribution has received little attention to date.

Concentrated photovoltaic (CPV) systems can achieve high energy conversion efficiencies due to their use of concentrating optics and highly efficient solar cells; however, power losses arising from the front surface reflection and metallization shading typically contribute a significant fraction to the total power loss for these devices. In flat silicon photovoltaic (PV) modules, the front‐metal finger shape is often shaped to minimize shading losses. Finger shape is even more relevant for CPV cells where the current density and front metal shading are much higher. This study compares the optical performance of five light management finger designs in CPV systems with two different refractive homogenizers. The optical efficiency and loss analysis were determined using ray‐tracing simulations. It is shown that shaped, light diverting metal fingers can improve the optical efficiency in CPV systems by up to 9.9% absolute compared to rectangular fingers, corresponding to an absolute cell efficiency increase of 3.0%. Although sharp edged triangular finger structures may be challenging to fabricate, significant optical gains can still be achieved with trapezoid or rounded cap finger shapes.

“…Absenteeism due to illness, especially long-term absenteeism (>1 year), continues to rise in Belgium (Verlinden, 2018). The main causes have been attributed to musculoskeletal disorders (MSDs) and psychosocial problems (Verlinden, 2018). In 2016, 40% of all sick days in Belgium were due to musculoskeletal complaints (Verlinden, 2018).…”

Background: Long-term absenteeism continues to rise in Belgium and musculoskeletal disorders (MSDs) have been considered a primary cause. However, there is still uncertainty about the prevalence of MSDs, and about the contribution of work-related factors in the etiology of MSDs. SALTSA, which was developed in 2001, is a European diagnostic criterion document that aims to standardize the reporting of work-related upper limb MSDs (ULMSDs). The purpose of this work-site study was to implement SALTSA in daily occupational health practice and to determine the prevalence of ULMSDs in a Belgian company. Methods: During health examinations, occupational health nurses and an occupational health physician screened employees in a company with ergonomically high-risk activities for the occurrence of ULMSDs using the SALTSA protocol. In order to explore associations between ULMSDs and lifestyle and work-related factors, bivariate and logistic regression analyses were performed. Findings: Three hundred and eight (94.0%, 308/328) employees were screened resulting in an ULMSD prevalence of 20.5% (95% CI = [16.0–25.3]). Rotator cuff syndrome was the most common condition. Prevalence varied significantly between men (9.6%, 95% CI = [5.6–14.9]) and women (35.0%, 95% CI = [26.9–43.9]). Being female ( p < .001) and working in the cabling assembly unit ( p = .002) were found to be significant predictors of ULMSDs. Conclusion/Application to Practice: By using the SALTSA protocol in occupational health practices, ULMSDs can be screened unequivocally, enabling comparisons between different occupational sectors and countries. Occupational health nurses can play an important role in detecting and screening MSDs among workers.
