Abstract	For global energy supply and demand to be reached, non-traditional energy sources like photovoltaic (PV) technology are crucial. With a market share of 95% and an efficiency range of 20 to 25%, crystalline solar cells (c-Si) based on aluminium back surface (Al-B.S.F.) and passivated emitter and rear contact (P.E.R.C.) exhibit efficiency levels of 20% and 25%, respectively. The SHJ solar cells have passivation of i:a-si:H and doped a-Si:H, enabling 26.7% efficiency; however, the fabrication process is complicated for doped a-Si:H contacts and emits hazardous gases, and energy losses from parasitic absorption and Auger recombination are still present. Transition metal oxides (TMOs) contacts as an alternate can be fabricated at low temperatures and have more economical, opto electrical, and other properties that can reduce energy losses. TMOs act as carrier-selective contacts, allowing one kind of charge carrier to pass while obstructing the other. TMOs with double-asymmetric heterocontact with an efficiency of 24.83% have been attained by c-Si solar cells and a potential of above 28.4%. By adjusting TMOs deposition thickness, assessing passivation quality, and measuring Voc, Isc, and FF using a solar simulator with Keithley, the I-V measurement, and different spectroscopy, it is possible to experimentally choose the TMOs material and tune it with c-Si for good passivation. By reducing manufacturing costs and establishing a levelized cost of energy (LCOE), solar power becomes more competitive and economically viable.
