Benefits of technology

The present invention relates to an improved type of photosensor that uses Titanum oxides (TiO2) instead of traditional photoconductors for better safety and environmental protection during use over longer periods than previous designs. This new design has several technical benefits such as ease of manufacturing, lower costs compared to existing technology, high stability at extreme temperatures or humidity levels, and increased durability when used under harsh conditions like sunlight without losing its effectiveness due to damage caused by external factors like UV light exposure.

Problems solved by technology

This patents discuss how different types of plastic films made up of various metals like Cadmium Sulfur Tellurum Tellurosynum Layer Thermosetting Polymer (CNT), Polyvinyl Chloro Acetal Resinate(PVC)) Platinum Lead Colloidal Crystal Phosphorus Oxysulfon Pigment Disclosed in Japanese Patent No. 70249065. These technical problem addressed in this patented text include finding ways to produce durable, safe, and highly efficient photovoltaics without harmful substances called cobalt chroma tungsten bronze (CoCrNb2), while also addressing concerns over their disposal processes and increasing prices associated with them.
