What are some challenges for the future of solar pv cells?

Research conducted by NREL suggests that every dollar saved on your energy bill due to the installation of a solar energy source increases approximately $20 to the current value of your property. In the United States, these cost decreases are expected to increase solar energy produced by at least 700% by 2050. However, there must be a concerted effort in development, innovation, installation and policies based on photovoltaic technology to achieve this unprecedented feat. A research team from the University of Michigan recently published a study of this type in which they identified the need for organic photovoltaic cells (OPV) with a longer operating life.

The main problem with solar energy is that solar cells contain silicon, even silicon is recyclable, but its production produces greenhouse gases that seriously affect the environment. This study focused on the current situation and management of the end-of-life solar photovoltaic (PV) module in Bangladesh. Currently, the cost of silicon-based solar cells continues to decline and, despite predictions to the contrary, the cost of silicon itself continues to decline. By switching from fullerene acceptors to physically modified non-fullerene (NFA) acceptors, the team maintained a high efficiency of 80% in OPVs and, at the same time, extended their intrinsic lifespan to more than 5.6 x 104 h, which is equivalent to 30 years.

If the solar cell always points toward the Sun, it will be hit by many more photons than if it were only aimed at the Sun around noon. Like multi-layer cells, thin-film solar cells are a bit complicated to manufacture, limiting their application, but research is continuing. Solar cells with more than one layer of material that captures light can capture more photons than solar cells with a single layer. Theoretically, about 32% of light energy could be converted into electrical energy with a silicon solar cell.

Another way to improve the performance of solar cells is to focus their efficiency so that they can better convert the energy of sunlight into electricity. Alternatives to silicon solar cells have been developed, but they are not advanced enough to be commercially viable. In addition to several advantages of the solar photovoltaic system, there are challenges associated with this technology.
