“…The analysis of the response of the solar cell whatever the regime poses the problem of the contribution of each of its constituent parts (emitter, space charge region, base), and as well as the recombination phenomena which occur there (bulk and surfaces). Thus certain techniques for determining the recombination parameters [31] impose conditions in:…”

The monochromatic absorption coefficient of silicon, inducing the light penetration depth into the base of the solar cell, is used to determine the optimum thickness necessary for the production of a large photocurrent. The absorption-generation-diffusion and recombination (bulk and surface) phenomena are taken into account in the excess minority carrier continuity equation. The solution of this equation gives the photocurrent according to absorption and electronic parameters. Then from the obtained short circuit photocurrent expression, excess minority carrier back surface recombination velocity is determined, function of the monochromatic absorption coefficient at a given wavelength. This latter plotted versus base thickness yields the optimum thickness of an n + -p-p + solar cell, for each wavelength, which is in the range close to the energy band gap of the silicon material. This study provides a tool for improvement solar cell manufacture processes, through the mathematical relationship obtained from the thickness limit according to the absorption coefficient that allows base width optimization.

“…Solar Decathlon competitions worldwide also make the students compete to design and fabricate net-zero buildings. The students of Team SHUNYA, who participated in Solar Decathlon Europe 2014 [45], felt that they learned more from participating in this 18-month-long competition than their curriculum, highlighting the importance of experiential education, learning by doing, and connecting the curriculum to real-world problem solving. SHUNYA, which means zero in Hindi, is an acronym for "Sustainable Habitats for an Urbanizing Nation by its Young Aspirants".…”

This study addresses the urgent need for comprehensive climate education amid a climate emergency. Human (energy) behaviors are developed from childhood and early adulthood. This study hypothesizes that transcending a nation’s net-zero energy ambition can be accomplished through experiential education. An Urban Governance Lab plus nEt-Zero Energy league model is introduced. Various behavioral interventions are designed based on the principles of serious games. Discussions provide rich narratives on how a nation with so many diverse communities can forge a rapid net-zero transition. The blended multi-disciplinary STEM education can drive energy citizenship in campus-like communities. A scenarios-based analysis demonstrating the potential of the proposed model in shaping energy behavior in young citizens leading to net zero is presented. The results from the scenario analysis present optimistic evidence underlining how campus-like communities driven by bottom-up initiatives can realize net-zero ambition beyond hope.

“…As a result, the photogenerated carriers travel a distance (L) to reach the space charge region (SCR), in order to participate in the photocurrent. This distance is the diffusion length, and related by the Einstein relation, to the lifetime (τ) and the diffusion coefficient (D) which is influenced by physical parameters [9][10][11][12] due to manufacturing and the operating [13] conditions of the solar cell.…”

The temperature resonance of the scattering coefficient of the minority charge carriers is applied to the determination of the optimum thickness of an (p) base (n + /p /p + ) bifacial silicon solar cell, placed under magnetic field, and illuminated by the back side (p + ) by a monochromatic light with constant flux, of short wavelength. The optimum thickness is obtained by the graphical method of the representation as a function of the thickness, expressions of minority carriers' recombination velocity on the rear side of the base, depending on both the diffusion coefficient and the absorption coefficient. The results show a reduction in the thickness of the base, making it possible to obtain an optimal photocurrent, and a saving of material for the industrial elaboration of solar cells.
