Abstract
Indonesia is an archipelagic nation that has many small islands where the average load is low and currently supplied by diesel power generators. The drawbacks from these generators are cost constraints from its operation. Solar cells are the solution of this problem with the support of daily average radiation in Indonesia of 4.8 kWh/m2/day. There has been a lot of technology for the construction of solar cells such as silicon based, copper indium gallium selenide (CIGS), which was already successfully commercialized. However, these technologies have been obsolete and started to reach its maximum potential. Perovskite solar cells have a very high future potential, due to the increase on the efficiency of this technology in a relatively short amount of time. The current challenge for the fabrication of perovskite solar cell is the material cost and fabrication cost. This paper discussed the low-cost fabrication of perovskite solar cell using only spin coating deposition method and relatively also low-cost materials for the structure of the perovskite solar cell itself. As a result, we achieve perovskite solar cell with VOC of 0.6 V, ISC of 13 mA, FF of 0.28, and 1.2% efficiency.

Summary
One of the best alternative renewable energy is solar energy utilization. The solar cells can solve the problem experienced by diesel power plant in Indonesia. Perovskite solar cells are a third generation of solar cells utilizing organic-metal halide perovskite materials, such as MAPbX3 (MA = CH3NH3+; X = Cl-, Br-, I-) as the light absorber. They have recently enticing due to its efficiency rating in the last four years [2]. Perovskite solar cell features a large band gap, large absorption coefficient, high carrier mobility, long carrier diffusion length and small binding energy [3]-[7]. Perovskite solar cell should be able to compete with conventional silicon-based solar cells and have become a new direction for developing high efficiency solar cells [8]
