In a project aimed at enhancing solar cell efficiency, a team of materials scientists is developing a new photovoltaic material 'Material PV'. This material is designed to have improved light absorption and charge transport properties. The development process of 'Material PV' involves a series of steps focusing on its semiconductor properties. The sequence of the material development is as follows: 'Material PV' is synthesized using a blend of organic semiconductors with complementary absorption spectra. The material then undergoes a doping process to modify its electrical conductivity and enhance charge carrier mobility. Nanostructuring techniques are applied to 'Material PV' to increase its surface area and optimize light-harvesting efficiency. Finally, the material's performance is tested in a prototype solar cell under varying light conditions to evaluate its photovoltaic efficiency. Based on this sequence, what is the primary challenge or objective in the development of 'Material PV' for use in solar cells? Options: A. Increasing the thermal stability of the material B. Maximizing the photovoltaic efficiency and power conversion efficiency C. Enhancing the mechanical flexibility of the solar cell D. Reducing the production cost of the photovoltaic material Hints: Consider the role of each step in the development process and how it contributes to the performance of a photovoltaic material. Reflect on the key properties that are crucial for a material to be effective in converting light into electricity. Think about the overarching goals in the field of solar energy, particularly in terms of efficiency and practical applicability. Don't use chatgpt please provide valuable answer
