La présente invention concerne un dispositif à un axe permettant de pister la course du soleil dans sa circonvolution afin d’apporter aux panneaux photovoltaïques (PV) le maximum d’ensoleillement quel que soit le moment de la journée pour améliorer leur rendement de manière significative. L’invention peut être couplée avec la demande de brevet n° FR2310044, qui permet d’adjoindre au PV une BOX en vue de valoriser la chaleur fatale produite en sous-face du PV sous forme d’électricité ou d’autres produits (hydrogène verte) et d’augmenter d’autant plus la productivité du parc solaire. Le procédé est entièrement automatisé, peu mécanisé (pas de moteur mais uniquement une pompe à faible consommation électrique), simple à installer et à maintenir pour les panneaux uniques, en série ou en champ et quelle que soit la conformation du terrain où ils sont implantés. Les traqueurs peuvent mutualiser certains moyens. Un logiciel de pilotage et de contrôle spécifique assure l’optimisation de la capture des rayonnements, l’automatisation et la surveillance à distance du système. L’invention peut permettre la récupération des eaux satellitaires au moyen de gouttières, leur stockage et leur valorisation limitant les effets néfastes pour l’environnement de leur écoulement sur le sol, elle peut également, dans sa version mettant en œuvre la BOX, autoriser le renversement total du bloc photovoltaïque qui expose alors aux intempéries

This disclosure pertains to snow removal systems, specifically systems designed to maintain the functional efficiency of solar panels by preventing the accumulation of snow on solar panels. Solar panels are devices that convert light into electricity and are commonly used in a variety of settings, from residential rooftops to large-scale solar farms. These panels consist of multiple solar cells made from semiconductor materials that exhibit the photovoltaic effect. The efficiency of solar panels is contingent upon their exposure to sunlight, which can be impeded by environmental factors such as the accumulation of snow. The technical background involves mechanisms and methods for preserving the optimal operational state of solar panels in environments subject to snowfall.

Stowing flexible tracker systems with the panel surfaces at a negative tilt angle during high wind is enhanced through optimizing around total system damping in order to address aerodynamic instabilities. Current flexible tracker designs function by avoiding the regions in which negative aerodynamic damping primarily occurs. Doing so requires them to stow at maximum absolute tilts to remain stable. However, methods disclosed here select system flexibility, system mechanical damping, and tracker stow angles to achieve a positive aerodynamic damping function and thus enable stable wind stow at lower than maximum tilt angles. The design approach addresses multiple current failure modes within the PV tracker industry while reducing installation cost relative to current designs.

Contacts for solar cells and other optoelectronic devices are provided. Embodiments described herein take advantage of the surface Fermi level pinning effect to build an electrical field inside of a semiconductor to extract or inject carriers for solar cells, photodetectors, and light-emitting device applications. For example, n-type or p-type two-dimensional (2D) materials can be used in contact with an n-type semiconductor to form a “p-region” so that a p-n junction, or an i-n or n-n+ junction can be constructed. Similarly, n-type or p-type 2D materials can be used in contact with a p-type semiconductor to form an “n-region” so that an n-p junction, or an i-p or p-p+ junction can be constructed. These structures can provide sufficiently high electrical field inside the semiconductor to extract photogenerated carriers in solar cells and photodetectors or inject minority carriers for light-emitting devices.
